Wimax VS LTE

4G Wimax Start Action in Indonesia

noreply@blogger.com (Mr_Oct) — Sat, 26 Jun 2010 23:59:00 +0000

End of June 2010, First Media will introduce the first Wimax 4G Internet service in Indonesia. It will do if the test certificate successfully pocketed operation-worthy (ULO) from the Directorate of Standardization Ministry Kominfo DGPT.

The first launching in the form of soft launch will be held at First Media on Monday, June 28, 2010, in Lippo Karawaci, Tangerang, Banten.
"After a long-awaited, 4G Wimax Broadband Internet technology has been present in Indonesia. Be the first to prove his greatness," wrote the prologue in Sitra WiMAX soft launch invitation.

Sitra Wimax is a trademark of First Media for broadband wireless access (BWA) nomadic 802.16d who won the tender for frequency licenses in the 2.3 GHz band. Lippo Group subsidiary that won the first zone (North Sumatera), with a tender value of USD 7.201 billion and zone 4 (Greater Jakarta and Banten) worth USD 121.201 billion.

Wimax is short for Worldwide Interoperability for Microwave told Access, a broadband wireless access technology (broadband wireless access / BWA), which have high speed access with a wide range. With data speeds theoretically up to 70 MBps, Wimax can be applied for last mile broadband connection, backhaul, and high speed enterprise.

Indonesia maintain Wimax Formerly, after that LTE

noreply@blogger.com (Mr_Oct) — Tue, 22 Jun 2010 04:51:00 +0000

The presence of technology Long Term Evolution (LTE) 4G cellular networks, had feared would make the service through a network Wimax Broadband Wireless Access (BWA), withered in the bud. However Menkominfo Tifatul Sembiring promise I will not ignore Wimax for LTE.

"LTE is still a long, preparation of tender had only eight months. For us the important synergistic, Wimax and LTE first new road," he said after the inauguration Tifatul Telkomsel LTE trials at the Hotel Grand Melia, Jakarta, Monday (06/21/2010).

Since the eight companies to win tenders BWA frequency licenses in 2.3 GHz band in mid 2009 and, until now there is no one who has held Wimax. Rather than operate it commercially, three of the eight companies that actually have to lose its license.

According to Heru Sutadi, a member of the Badan Regulasi Telekomunikasi Indonesia (BRTI), has urged his side together Kominfo five companies winning licenses in the 2.3 GHz BWA others to immediately commercialize WiMAX this year.

BWA licenses that winning companies are Telkom, Indosat Mega Media, First Media, Berca Hardayaperkasa, and Jasnita Telekomindo. Of the five companies, four of whom reportedly ready to launch WiMAX in the near future.

WIMAX Must Running in 2010

noreply@blogger.com (Mr_Oct) — Tue, 11 May 2010 04:52:00 +0000

Worldwide Interoperability for Microwave Access (Wimax) should be implemented this year. In addition because the technology is ready, the service also has issued a lot of money for licensing fees.

Similarly spoken by the Director of IT and Supply of PT Telkom, Indra Utoyo when found on the campus of Bandung Institute of Technology.

"Must. This year should be ready. We're already paying a license, and it's not cheap," he said.

For Telkom, Indra continues, Wimax will be used to complement the speedy service and 3G that he had.

"So long as these areas we can not serve, can be served with Wimax. So to complement our services," says this bespectacled man.

Asked how far the readiness of Telkom to roll out broadband services broadband this, Indra admitted today for Wimax services has entered into an investment committee.

"This investment Committee who will decide. Usually no longer if already signed. Just wait. No longer," he said.

Indra was optimistic that this service would be accepted by society. While the problem is still an expensive device that could basically be solved by common usage.

"This technology allows a wider range. So stay put knotted-node that has the potential. We will gradually with degree of order," he said.

WiMax takes But Poor Support

noreply@blogger.com (Mr_Oct) — Thu, 06 May 2010 11:56:00 +0000

WiMax is the most appropriate platform to bring broadband services in urban or rural. Target 50 million broadband users could be realized in 2015. But, unfortunately, less supported by the government.

WiMax Forum Indonesian Chairperson Sylvia Sumarlin called WiMax will not have to worry about displacing existing operators. Internet mobile technology will not be eroded mobile voice, because it's different segmentation services. "Although the WiMax technology such as VoIP, but there will still be more clear if we called up by using a mobile phone," he told yesterday.

But he cautioned forward a full mobile Internet technology with wireless broadband access (WBA) would indeed be very expensive and sophisticated, so it is possible the mobile industry will lose if it does not innovate.

"If the market is another talk later about this mobile technology, then it could be another story. But so far I think still are complementary, "adds Sylvia.

Vice President of WiMAX Forum, Dr. Mo Shakouri said Indonesia needs broadband access within the immediate and affordable to meet the needs of the market. However, from more than 150 million mobile subscribers in Indonesia, only less than half a million who have access to broadband connections.

"Though WiMax is the most appropriate platform to achieve the deployment of broadband services in central cities and rural areas in order to achieve its target of 50 million users in Indonesia in 2015," he explained.

Sylvia reveals, the target 50 million WiMax users in 2015 can be realized, because of technological developments can not be prevented. Moreover, to become an economically strong state, it must develop its local content. Local content that includes the application, and not just hardware or software alone.

He regretted the government had yet to provide support to the wireless telecommunications industry entirely, as evidenced from the 802.16d standard is still applied.

Whereas a number of local companies signed the Domestic Industry Preparedness Charter which marks the readiness of equipment manufacturers to support the implementation of Homeland WiMax.

"We still recommend that the government's telecommunications industry using 802.16d, 802.16e but by no means rule out the already used many developed countries. Even apart 802.16e, even if the device 16m Indonesian market is ready, it is not impossible to launch 2-3 more years, "adds Sylvia.

Meanwhile, Chairman of the Indonesian Telecommunications Society (Masterl) Setyanto P Santoso said the telecommunications industry in the country is actually already requires 802.16e for various video applications and data services, animation, and sound more sophisticated.

"If the government really serious then do not have to wait for the perfect research for technology transfer. Operators are also challenged by the government, "he said.

Head of Public Relations Gatot S Dewa Broto Depkominfo when contacted denied terpisah.COM less government support BWA in Indonesia. He states 802.16d encouraged to domestic products, while still an international 802.16e and 802.16m.

"We have not been able to provide current license to provide service for existing devices industry is still using the 16d, not just a service provider," he explained.

Billy called 802.16e has not been able to be used instead. Since two years ago, is ready, but the government saw the overall industry is still using 802.16d chipset.

He cited the deployment of WiMax has been on schedule. Companies that win the tender BWA is currently doing technical preparations after making payment obligations. "Maybe just six months may be granted license to provide," he explained.

Wimax Slow Growth Predicted in Indonesia

noreply@blogger.com (Mr_Oct) — Wed, 05 May 2010 23:39:00 +0000

Technology for Worldwide Interoperability Microwave Access (Wimax)) which is a broadband wireless access technology (broadband wireless access or BWA) with high-speed access and wide-reaching is predicted to grow more slowly in Indonesia.

"WiMAX does not have the mobility to provide a broadband connection to the remote villages in Indonesia," said Senior Director, Services, GSM Association (GSMA), Jaikishan Rajaraman in his press statement here on Monday.

He added that, if compared with competitors such as 3G/HSPA technology, WiMAX is not yet able to offer Mobile Broadband connection that provides solutions range up to the outposts of the island, because they still keep playing in coverage more specific and more positive role as a complement.

According to him, until now, only HSPA technology that can reach into any area and has real mobility capabilities through a variety of devices available today.

"Furthermore, WiMAX is better known simply as a substitute for fixed line broadband so can not offer true mobility," he said.

According to Ovum, a leading industry analysts, WiMAX will only control less than 5 percent of 1.5bn joint fixed and mobile broadband access in markets of developing countries in 2014.

"Penetration of WiMAX has been very slow according to analyst firm Maravedis, there are about 200 WiMAX networks, and about 200 networks that are still in the trial period, in 135 countries and globally only serve 4.73 million subscribers," he said.

If compared with the competitors that HSPA has more than 200 million HSPA connections with the growth rate of more than 9 million per month, all over the world, then Wimax already very far behind, he said.

Currently there are only about 120 WiMAX devices have now been certified or far behind compared with more than 1800 for the HSPA.

"HSPA Ecosystem enables the creation of large economies of scale and also because of tight competition, so there are many choices for consumers and businesses," he said.

WiMAX itself is an evolution from previous BWA technology with the features of the more interesting that deliver high data speeds and is the technology with open standards.

Wimax technology is not proprietary to achieve 70 Mbps data speeds that is claimed to be applied for broadband connection "last mile", or backhaul.

BWA Jabotabek re-Tender

noreply@blogger.com (Mr_Oct) — Wed, 05 May 2010 14:22:00 +0000

Some telecommunications operators would be doing some intensive preparation.

One of the winning bidder BWA or Selection Based Local Fixed Network Using Packet Switched Radio Frequency Band 2.3 GHz for Wireless Broadband Service Needs (wireless broadband) technology WiMax 'fallen' alias operate principle licenses revoked.

It is a PT Internux. This company won the bidding Banten and Greater zone (zone 4) with PT First Media Tbk. Internux won a tender with a bid price of less than Rp 110 billion. Meanwhile, the price offered in the first rank of First Media is Rp 121.2 billion.

However, Internux then do not pay the total liabilities plus Radio Frequency BHP and penalties until the end of the specified time limit, ie, February 22, 2010.

"Under the rules, which fail to pay will we pull the permit implementation. We plan to hold a re-tendering. What is clear, broad band which must be left untapped, "said Gatot S Dewa Broto, Head of Information and Public Relations of the Ministry of Communications and Informatics at VIVAnews in Jakarta, Monday, May 3, 2010.

However, Gatot said the government will not open a new tender soon. "The process (license revocation) was not finished. After all we have to avoid any allegations of fraud. This decision was not new. If the tender is opened, later thought to have been deliberately want to re-tender, "he said.

There will be regulations governing the implementation of re-tendering. Billy explained, will be more tender committee was also formed. "What is certain this year. While there is no discussion in that direction from the Minister, "said Billy. "We are sad. Because, like words, our WiMax merchandise was not selling, "he said.

According to the latest news from Kemenkominfo, until now received information that several international telecommunications has been, is, and will do some intensive preparation. Some had already completed the implementation of the tender for the procurement of equipment.

"Then there are still internally trial after several Central Office Monitoring and also the office of Radio Frequency Monitoring Loka DGPT perform clearance or clearance to use radio frequency radio frequency band 2360 - 2390 MHz illegally, according to the warrant Director of Radio Frequency Spectrum Management Tulus Rahardjo on March 23, 2010 via letter No. 539/T/DJT.4/KOMINFO/3/2010, "said Billy.

Billy recognized, although based on reports collected there is some violation, but it also became one of the principal problems is the tendency of the relevant telecommunications vertigo to start, because it bumped the price of equipment to customer problems.

"While in the relevant telecommunications operators that are used as base stations is that its capacity is still low, only able to serve 20 customers," said Billy.

2 Winners WiMax Tender Immediately Withdrawn

noreply@blogger.com (Mr_Oct) — Tue, 04 May 2010 03:39:00 +0000

The government plans to re-tender
Showed its seriousness to develop Broadband Wireless Access (BWA) in Indonesia, the government finally decided to hold a tender early last year which was marked by the signing of two ministerial regulations (Candy) and two Ministerial Decree (KM) by the Communication and Information Minister Muhammad Nuh.

But, unfortunately, up to the limit payments last chance on 26 April 2010, two consortia, namely the consortium of PT Rahajasa Media Internet on behalf of the Consortium for Wimax Indonesia (KWI) and the consortium of PT Comtronics Systems and PT Adiwarta Perdania, unable to meet their payment obligations.

"It was decided that his rights as a winner and will soon operate principle licenses revoked," said Gatot S Dewa Broto, Head of Information and Public Relations of the Ministry of Communications and Informatics at VIVAnews in Jakarta, May 3, 2010.

"Today, we are conducting a verification. Its function is to make sure if they really do not meet the requirements. Because, who knew they had had to pay, but the smell hit technical obstacles, "said Billy.

If during the verification process, the government did not find any obstacles to be revoked, it will then be issued Decree (SK) Minister.

For information, the two consortia that include KWI and the consortium of PT Comtronics Systems and PT Adiwarta Perdania is the winner of the tender BWA or Selection Based Local Fixed Network Using Packet Switched Radio Frequency Band 2.3 GHz for Wireless Broadband Service Needs (wireless broadband) technology WiMax.

The zone, which was won by a consortium bidding PT Comtronics Systems and PT Adiwarta Perdania is minus Botabek zone of West Java, Central Java and East Java. While supply zone, which was won by the BCI, including in Papua, Maluku and North Maluku, and Riau Islands (Batam and Bintan).

"To replace the winners who fail to meet the payments, the government plans to re-tender, but do not know when," said Billy.

"For sure, we are not in a hurry. Because, it's failed to pay the new consortium. If it suddenly re-direct the new tender was announced, I'll think we did intentionally make a tender back. Government to avoid that, "he said.

802.16 / m Next Generation Mobile Wimax Part 1

noreply@blogger.com (Mr_Oct) — Mon, 26 Apr 2010 12:01:00 +0000

Mobile WiMAX 802.16 / m is the 'air interface' which offers a new spectrum efficiency and throughput in accordance with the requirements of ITU for 4G technology development kedepannnya. IEEE 802.16 / m is to standardize data transmission speed is higher on mobile devices. Data speeds up to 1Gbps and possible distribution via wireless broadband access is an alternative to cable, DSL, and 3G. Broadband spectrum that is used in the frequency range from 2.3 GHz-3.5 GHz and the use of OFDM / OFDMA (Orthogonal Frequency Division Multiplexing Access). With the use of OFDM / OFDMA is considered to bring efficiency gains in terms of frequency bandwidth, coverage areas, installation and cost. Development by the IEEE 802.16 standardization began in March 2007 and scheduled for completion around the year 2009.

Institute of Electrical and Electronics (IEEE) is developing the standardization of 802.16 / m, which is the latest version of the standardization of IEEE 802.16 (Wimax). This standardization development began in March 2007 and planned for completion by the end of 2009. Created with the aim to increase data transfer speed reaches 1 Gbps in quiet conditions and 100 Mbps on the condition of moving (mobile). Standardization 802.16 / m harmony with the requirements of the International Telecommunication Union (ITU) for the development of 4G technology. IEEE to develop a competitive radio access technology and has a significant advantage ("Gigabit Wimax") and be able to compete with ITU R / IMT Advanched. MIMO technology (Multiple In / Multiple Out) and a meruapakan SOFDMA modulasimulticarrier technique that uses subchanelisasi also be the basis for development of this standard.

Development of Wireless Broadband
Success in Wireline Broadband (Cable / DSL) and Wi-Fi Mobile Broadband impacted by the emergence of the Internet, and coupled with increasing demand. Consumers need a mobile internet, which has the ability to access the Internet anywhere and anytime. Therefore we need a standardization for mobile internet technologies, and also needed an IP-based wireless broadband network that has a quality similar to wireline broadband mobility with additional capabilities. In other words, it takes a mobile broadband technology in accordance with the requirements of mobile Internet. IEEE 802.16 answered those needs by developing 802.16 / m. The features found on 802.16 / m mobile wimax as contained in the following table:

802.16 / m is one of the candidates for IMT-Advanced Evaluation Process and also a New Advanced Water Interface that operates in licensed bands.

Wimax vs LTE

noreply@blogger.com (Mr_Oct) — Mon, 26 Apr 2010 11:40:00 +0000

Two new wireless technologies are emerging seem to compete. WiMAX (Worldwide Interoperability for Microwave Access) was born earlier than LTE (Long Term Evolution). In the device and handset vendors support more readily than LTE, WiMAX in 2009. While LTE will be developed after the year 2010. Each of these technologies by the International Telecommunications Union (ITU) will be candidates for 4G network standards (at least 100 Mbps for data transfer) at least in the year 2009.

In LTE superior speed over the current generation of WiMAX (IEEE.802.16e). LTE can deliver downlink speeds up to 100 Mbps and 50 Mbps uplink and can be expanded up to 250 Mbps for downstream. However, this speed will compete with WiMAX generation II (IEEE.802.16m) which will be updated in the year 2009. WiMAX II will run on the mode with a speed of 100 Mbps Mobile and Fixed up to 1 Gbps (unusual for exchanging data wirelessly). In addition to LTE and WiMAX, there is another technology that is almost similar to the LTE UMB (Ultra Mobile Broadband), but its development is a CDMA base. Even its downstream UMB is greater than the LTE, which reached 288 Mbps (with band 20 Hz).

LTE and WiMAX Market Opportunities

LTE, which is a development of GSM and CDMA predicted it would be easy to penetrate into the market. GSM technology has been used predominantly (80%) in all parts of the world. GSM and CDMA networks have been very widespread, especially in the cities of the world. It is therefore not surprised to LTE will have a larger market with WiMAX in the appeal. However, WiMAX technology is more economical for the development of new networks in rural areas. WiMAX has an investment cost which much cheaper than GSM base stations. If one GSM base stations will cost up to Rp1 billion invetasi the same number of units for WiMAX base stations need only cost approximately USD 60 million only. Market segmentation using WiMAX and LTE are clear. WiMAX will prevail in the rural areas that are difficult and rarely have BTS. While LTE will thrive in urban areas, utilize networks of base stations are already available.

Mobile WiMAX Technology

noreply@blogger.com (Mr_Oct) — Fri, 23 Apr 2010 01:57:00 +0000

Mobile WiMAX is a wireless broadband solution that enables mobile and fixed network konfergensi broadband via an extensive radio access technology and flexible network architecture. Water interface on Mobile WiMAX applying Orthogonal Frequency Division Multiple Access (OFDMA) to obtain multi-path performance is better in the environment of Non Line Of Sight (NLOS). To support the growing bandwidth channel (scalable) from 1.25 MHz to 20 MHz, IEEE 802.16e introduces the Scalable-OFDMA (SOFDMA), Mobile Technical Group (MTG) on the WiMAX Forum is developing the Mobile WiMAX system profiles that enable mobile system configured

Mobile WiMAX Architecture
According to the WiMAX Forum, Mobile WiMAX architecture consists of three main parts, namely:

• User terminals are used by end-users to access the network.

• Access Service Network (ASN), which consists of one or more BS and one or more ASN gateways that form the radio access network.

• Connectivity Service Network (CSN), which provides IP connectivity and all the core functions of the Internet Protocol Network.

Network Working Group (NWG) WiMAX Forum is an organization that has authority to design the network architecture and protocols with the Mobile WiMAX air interface that has been standardized by the IEEE 802.16e standard. NGW WiMAX defines several entities in the Mobile WiMAX network:

• Base Station (BS)
Base Station has a main function is to build a relationship with the mobile station. BS also has another function that is set micromobility management as the process of handover, radio resource management.

• Access Service Network - Gateway (ASN-GW)
ASN-GW functions to regulate the location management and paging intra-ASN, set AAA customers, and perform the function of mobile IP.

• Connectivity Service Network (CSN)
Function provides connectivity to the Internet, ASP and other common network functions.

Frequency Allocation and Duplexing Systems
In the WiMAX technology have provided some of the frequency spectrum between 2.3 GHz others, 2.5 GHz, 3.3 GHz, 3.5 GHz, 5.8 GHz and 10.5 GHz. Use of these frequency allocation is different for each country in accordance with the conditions and policies of each country. The frequency used is 2.3 GHz frequency spectrum. This frequency was chosen because the Indonesian government plans to allocate the 2.3 GHz frequency spectrum for Mobile WiMAX network (IEEE 802.16e) with a channel bandwidth used by each of 10 MHz although there is currently no definite policy. On the frequency of policy direction in Indonesia, 2.3 GHz frequency has a frequency range of 2300-2390 MHz, where 10 MHz is used for the buffer (buffer) against out-of band emission from the WLAN / WiFi 2.4 GHz

While for the system used is the TDD duplexing (time division duplex). TDD uses a single frequency channel is used as ransmitter and receivers but in a different time. Consequently TDD frame is divided into the data stream and each frame is divided into time slots for sending and receiving. This allows the transmission of data in a single frequency only.

Propagation Models for Mobile WiMAX
Propagation channel model used in Mobile WiMAX is the propagation model COST 231-Hata. COST-231 model as an extension Hatta model is limited to use with the following characteristics:

Frequency (f): 1500-2000 MHz.

Height of base station antennas (hb): 30-200 m

High antenna mobile station (hm): 10-10 m

Distance Tx - Rx (R): 10-20 km

This channel model is also called the PCS model Extension to Hata Model, which is a formula developed from Hatta Okumura model for PCS frequencies (2 GHz). Okumura-Hata propagation model defined by the following equation:

Where L = attenuation path

fc = Frequency (MHz)

hb = base station antenna height (m)

hm = mobile station antenna height (m)

a (hm) = correction factor mobile station antenna height

R = cell radius (km)

CM = 0 dB, for medium-size cities and suburban area

CM = 3 dB, for the metropolitan area.

The value of correction factor mobile station antenna height (a (hm)) is

By knowing the value of link margin from the calculation of link budget, and by using the above equation can be calculated pathloss coverage range of the cell and also the number of cells required to cover certain areas.

Cell radius

Calculation of Cell Count
Calculation of cell numbers based on radius coverage area approach to the area covered by the reviews. The selection of architecture in the plan to use cellular architecture approach. Coverage area for a cell with a hexagonal configuration is

Where:

L = Coverage area

R = maximum cell range

K = constant accounting for the secto

Local vendors held a WiMax to affordable Internet services

noreply@blogger.com (Mr_Oct) — Tue, 20 Apr 2010 23:38:00 +0000

Government and local industry optimistic WiMax operators will be held for the Wimax internet service that is affordable, because the market economies of scale will be quickly achieved.

Suhono Harso Supangkat, special staff Minister for Communications and Information Technology (Communication and Information Minister), said the local industry does not need to worry too much for responding to the high costs that are borne by the operator of the tender results.

"According to our calculation, if the existing customer base above 100,000, the terminal price of the CPE [customer premise equipment] will be getting cheaper," he said.
According Suhono, for any payment frequency, the operator will pay up front fee (the cost in advance) with a specified percentage of capital expenditure. With that, the operator has to calculate his courage in allocating expenditures device.
"They've dared to take on the WiMAX business model, how many potential users in the region and how it can provide cheaper services. The hope with the scale of the use of a lot in 15 zone, CPE and base transceiver station [BTS] can be cheap, "he explained.
On the other hand, continued Suhono, the presence of new local operators Berca Hardaya Perkasa deserves a chance.
"Since the prequalification committee has been assessing their competence and in this case given the space to compete healthily," he said.
A number of local manufacturing has followed the procurement process 2.3 GHz WiMax devices in a number of operators, including PT Telkom and PT Indosat Tbk. Industry estimates that new orders will be massive WiMax device in October 2009.
Gatot Tetuko, Director of Global Technology Research, is optimistic all the WiMax device industry would gain market share from the first tender for the BWA.

"Most of them joined in Aptiki [Indonesian Telecommunications Equipment Manufacturers Association] and competed with a specialization in their respective area," he said.
This temporary Aptiki consisting of PT Inti, PT LEN, PT Quasar, PT Harrif, Xirka, Trg, and CMI. Industrial production volume was hoping the base will still be large in order to decrease costs and prices are relatively affordable in the end user.

Budi Permana, President Director of PT Daya Tunggal Engineering Hariff-local WiMax component manufacturing, previously said the technical improvements including the revision of the device is held in anticipation of bulk orders.
"We estimate a mass order on October 2009 or 2 months after the bidding process," he said.

National telecommunication equipment producers claim their respective strengths to be involved in the implementation of WiMax tender that was held last year.

Irfan Setiaputra, president director of PT Inti, revealed his side had extensive experience in the carpet of telecommunications equipment in the country, both in remote areas especially in Java.
Besides the sole right ever to hold the installation of a central digital communication across Indonesia from PT Telkom Tbk, a strategic SOEs was later to install and maintain devices that belong to three major cellular operators.

"In any area, even remote areas, we've been involved [installation]. Want in Aceh, to Papua, Indonesia's fixed. Vary thin, "he told Business in Bandung last week
Thus, further Irfan, is optimistic his side can get contract work from the winning bidder who incidentally has no experience in installing the device core and outlying areas.
PT Inti claim is not fully prepared to deal with tendering for projects in the near future. That's because the state is still preparing the human resources, devices, and related systems.
However, if the tender continuation of any such licensee conducted by the end of this, PT Inti fully prepared to be third party operator designated installer winner.

"Obviously, we're ready to go alone. Working on a contract alone, if victorious even before the existing consortium of Red and White that would capture the opportunities of development of this network. "
The consortium was formed earlier this year of former Managing Director of Nucleus Abdul Aziz, with other members. PT Len Industries, PT Pos Indonesia, and PT Quasar. However, with time, the consortium did not move anymore.

Dahyar, Corporate Communications PT Indonesian Tower, adding a subsidiary specializing in WiMax equipment, namely PT Teknologi Riset Global (TRG), already has all the components and are just waiting for production.

WIMAX Elements

noreply@blogger.com (Mr_Oct) — Tue, 20 Apr 2010 22:24:00 +0000

Base Station (BS)
Element / WiMAX devices generally consist of BS in the center and the CPE at the customer side. However there is still an additional devices like antennas, cables and other accessories. Is a device transceiver (transmitter and receiver) that is usually installed one location (colocated) with a network of Internet Protocol (IP). From this base station will be connected to multiple CPE interfaces with media of radio waves (RF) WiMAX standard. BS components consist of:

• NPU - networking card processing unit)
• AU - access unit card (up to 6 +1)
• PIU - power interface unit (1 +1)
• AVU - Ventilation water unit
• PSU - power supply unit - (3 +1)
In general (Customer Premises Equipment) or a customer site CPE equipment consists of the Outdoor Unit (ODU) and Indoor Units (IDUs), there is a separate radio device and there is integrated with the antenna.
Base Station has a main function is to build a relationship with the mobile station. BS also has another function that is set micromobility management as the process of handover, radio resource management.
Base Transceiver Station. serves to bridge the communication device user and the network to another network.
Where the base station (radio and antenna) is assumed for the radio station and then make the delivery of information / data (Internet access) and subscription tools such as WiMAX CPE that is used to receive services.

WiMAX Radio
A radio consists of a transmitter (sender) and a receiver (receiver).
Aristektur WiMAX is a simple architecture, was built with two major components, radios and antennas. Many products that offer WiMAX radio base station device separately with antenna. Conversely, many CPE devices on offer are 2 types of CPE solutions with an external antenna to the building and the CPE as an indoor subscriber devices, such as the following picture:
1. Outdoor CPE

2. Indoor CPE

CPE is a liaison function between the antenna via radio waves to the customer / Drivers

WiMAX Antenna
Type of antenna that is designed for the needs of different applications of WiMAX antenna, like the antenna that is used on car radios, mobile phones, FM radio, or TV is designed to optimize the performance of the receiver signal. Picture above shows the 3 main types commonly used for the development of WiMAX.
From Top to take are:

1. Omnidirectional Antenna
2. Sector Antenna
3. Panel antenna, has a special function.

Omni Directional Antenna

Omni directional antenna is used to configure point-to-multipoint A major drawback to the use of omni directional antenna is the use and wastage of energy in the process of broadcasting to 360 degrees. This is a restriction on the distance and the strength of the signal end. Omni directional is ideally used in situations where the subscriber / customer who many are very close to the Base Station. As an example of omni directional applications where there is a WiFi hotspot coverage area 100 yards and connected customers concentrated in areas that are not too large

Sectoral Antenna

Sector Antenna / Sectoral focus on areas that focused sectoral antenna device, with a focus on the spread signal on a focused area, providing a wider coverage area and energy / power is used less. Many operators prefer to use sector antennas to cover 360 degrees of service area instead of using omni directional antennas, this is related to better performance for sectoral antenna.

Panel Antenna

Panel antennas are often used for the application of point-to-point. Panel antennas are usually shaped flat panel with a size of approximately 30 cm square. Panel antenna can be configured properly to use the casing / box or rectangular. Power configuration is done by providing electricity through an ethernet cable is connected to the radio / antenna. This kind of power source known as Power over Ethernet (PoE).

Installation Tools Subscriber Station (SS)
1. Determining Position with BTS Antenna
To perform Antenna Installation on the SS side there are several things that must be considered and which should be prepared among others with BTS Antenna Position Determining, with the assumption that as a subscriber should adjust our poisi with the BTS and the distance that must be exceeded by BTS
2. Installing the Antenna to the pole
Before the antenna is directed to the first BTS antennas BWA (Broadband Wireless Access) is prepared, among others, pemasanga antenna to the mast, so easily directed antennas.
3. Antenna & Cable Installation Cable Ground
To connect the antenna keperangkat BWA necessary cables, which are used for the antenna used penhubung Coaxial Cables
4. d. Interconnection BWA
The next step is to connect through a backbone through the terminal station.

Differences Wireless and Wimax

noreply@blogger.com (Mr_Oct) — Tue, 20 Apr 2010 22:09:00 +0000

Wireless anything what advantages and disadvantages?

Advantages:
When compared with dial-up
· Fast as broadband access
· IP numbers can change, such as Dial-Up Access
· Can access anywhere, provided in hotspot areas
· Cheap, fast and flexible
· Umbrella for many users in a hotspot.
Disadvantages:
· To use the WiFi we must exist in an area accessible by WiFi or the term 'hotspot'.
· WiFi coverage area is still small, the signal can not penetrate walls.
· Access Point is more easily infiltrated by a virus
· Bugged easy data exchange

Wimax anything what advantages and disadvantages?

Advantages:
· Fast as broadband access
· Infrastructure development much faster and cheaper than broadband access
· Wider coverage area than WiFi and broadband access
· WiMAX will be complementary as well as the new challenger is now mainly on wireless technology
· Target new markets for companies that carry out the wireless
Mikrolektronik · The producers will get a new land to be done
· End users will get much choice in the internet. WiMAX is one technology that can facilitate us to connect to the internet easily and quality
· It has many features that so far there has not been on WiFi technology with IEEE 802.11 standards
° from its coverage only in terms of achieving the maximum 50 kilometers, WiMAX has a very large contribution
Disadvantages:
· As happened with other countries in the world, the Indonesian government had not determined the frequency of WiMAX that will be used. Most likely the first vendor to make WiMAX devices in the 3.5 GHz frequency. While in Indonesia, the frequency is also used for satellite communications. Therefore necessary to determine the appropriate frequency range to good advantage for operators, regulators and users.
· Price infrastructure equipment that is still very expensive
· Technology is still evolving and hold, so that investments can go wrong.
· Too many types of devices that are not mutually compatible.
· It takes experience to install devices
Having trouble will face another Indonesian people that legislation is not yet ready to adapt this technology for WiMax devices if manufacturers had to make a PCMCIA card or USB-based nomadic using WiMax standards, the device will be easy to get anywhere.

Benefits And System Components of WIMAX

noreply@blogger.com (Mr_Oct) — Tue, 20 Apr 2010 21:50:00 +0000

WiMAX Benefits
Bandwidth and reach of WiMAX enabled technology is used in the following applications:
Linking one-Wi-Fi hotspot with other Wi-Fi hotspots and the Internet;
-Providing the latest broadband access alternatives other than cable and DSL;
-Provide telecommunications services and high speed data;
-Provide a different source for internet connectivity
as part of the company's sustainability plans. Where, if
a company has an Internet connection and cable-based
wireless, especially from different providers, such connectivity
will not be affected by the unavailability of the same services.

WiMAX System Components
A WiMAX system consists of two parts:
WiMAX transmitter mast, similar to the concept of mobile phone transmitter mast, where a pole WiMAX transmitter can cover a relatively wide area (~ 8000 sq km) Recipients of WiMAX, which may be a small box or PCMCIA card, or can be implemented into the laptop, as well as WiFi access now.

WiMAX transmitting station can be connected pole directly to the Internet using cable-based connections with high bandwidth (eg, T3 lines). Can also connect with other WiMAX transmitter with microwave connections. Connections to other transmitters (often referred to by the name of backhaul) and the ability of a transmitter that can cover approximately 8000 square kilometers are two things that allows WiMAX to provide Internet coverage to suburban areas / hinterland.

Worldwide Interoperability for Microwave Access

noreply@blogger.com (Mr_Oct) — Tue, 20 Apr 2010 21:42:00 +0000

The need for connections, especially the Internet, which today has become even more secondary purposes in large cities, of course requires a good connection system, quickly and economically in order to utilize this facility will comfortably.
Two advances in today's Internet is a broadband (fast access) and wireless. WiMax standard combines these two things, provides high-speed Internet access via wireless connections. Because WiMAX can be accessed from a relatively far distance, this standard is
solution "recent" is effective for providing quick access to home users, and to create a hotspot-ho spots in places such as airports, campuses, and other small communities.
Based on the IEEE 802.16 standard, WiMAX uses architectural point-to-multipoint, which makes it an ideal way to provide quick access to the locations where cable-based connections will be very difficult and costly. WiMAX can also be a solution to provide fast access to suburban areas,
where high speed lines are not yet available. Compatibility is that WiMAX connections can be combined or transferred to LAN network or other wireless-based cable.

Analysis of Existing Problems and Solutions
If we talk about internet access at the present time, there are basically three options available, including:
1. Broadband access (high speed) - At home, we can use a DSL or cable modem. Or if we're in office, the company where we work can
using a T1 or T3 lines.
2. WiFi Access-At home, we can build a WiFi router that allows us to surf the web using a laptop. And on the way, we can find WiFi hot spots at various
restaurants, hotels, coffee shops, libraries, and so forth.
3. Dial-Up Access - Internet Access on this one are rarely used. Even if used, the likelihood is that if broadband access is not available, or if you assume that broadband access is too expensive.

The main problems that exist in the broadband access is
that the connection is very expensive and can not reach all areas. While the WiFi technology, hot-spot coverage is relatively very small, so coverage is very minimal.
Worse yet, access dial-up connection speeds are relatively small (maximum of 56 kbps) and the access costs are relatively more expensive compared to the two technologies mentioned above. From the formulation of the problems mentioned above, new technologies should ideally have the following features:
Form a high-speed broadband services wirelessly, so it will be cheaper than cable or DSL based technology and is easier to extend coverage to areas periphery and / or interior of a broad range as well as cellular phone networks, unlike WiFi hot spots are very limited scope.
WiMAX was formed to complement the existing shortcomings in Bluetooth and WiFi technology. In this case, WiMAX solutions provide an easy and relatively cheap. Although it is a wireless technology, unlike other wireless technologies, WiMAX has advantages such as access to mobile phone users, where WiMAX does not require distance
Direct view (line of sight) between the transmitter and receiver, and reach up to 50 kilometers (compared to WiFi which is only 30m). The speed of the data provided could reach 70Mbps (higher than 54Mbps WiFi only), which is sufficient to serve thousands of homes with high-speed access. On the other hand, WiMAX will also be very easy to configure and use - turn on the hardware you'll automatically from your mengoneksikan
WiMAX transmitters are available nearby.

WiMAX Standards

noreply@blogger.com (Mr_Oct) — Thu, 15 Apr 2010 17:14:00 +0000

WiMAX is an international standard of the BWA that refer to the IEEE 802.16 standard. This standard is then further developed by a joint forum between companies of the world who are members of the WiMAX Forum. IEEE 802.16 has several variants that are meant to develop performance and capabilities of WiMAX technology. Types of IEEE 802.16 standards can be seen in the following table:

Three variants of the most famous is the IEEE 802.16 (which first appeared), IEEE 802.16d or 802.16-2004 / IEEE 802.16-2005 and d / e. Difference and the third specification standards can be seen in Table 4.2. The fundamental difference between the IEEE 802.16 standard with the IEEE 802.16d standard is the type propagasinya, where IEEE 802.16 require LOS conditions, while in the IEEE 802.16d can operate at LOS and NLOS conditions. Development of the IEEE 802.16d standard for fixed and nomadic WiMAX is the IEEE 802.16e standard for mobile WiMAX focused.
WiMAX in the future development also made to support high mobility with fidelity mobile technology with IEEE 802.20 mobile WiMAX IEEE 802.16e, where both technologies have a lower bandwidth of IEEE 802.16 but has a very high mobility up to the speed of 125-250 km / hours.

IEEE 802.16 only fit for backhaul applications because they do not support the type of NLOS propagation, in contrast to the IEEE 802.16d and IEEE 802.16e can be used for backhaul and broadband personal service. Two final specification IEEE 802.16d and IEEE 802.16e has advantages and disadvantages of each that would be suitable depending on user mobility, data rates and coverage desired BS.

Wimax

noreply@blogger.com (Mr_Oct) — Tue, 13 Apr 2010 22:09:00 +0000

WiMAX technology is the basis of the IEEE 802.16 standard that allows data transmission services for Broadband Wireless Access (BWA) as an alternative to cable access or DSL. This teknologi is an attempt to answer the need for greater data rate, wide coverage, and compatibility between components in the network. Large throughput of course be an initial target of developing an access technology. This is driven by the increasingly diverse communications applications made by customers. With high data rate allows the network to be able to handle various kinds of transmission, both the transmission of voice, data, and video. WiMAX Forum states that only one Base Station, in theory, reach the cell coverage radius of 50 km with the ability of the system can transmit data at speeds up to 75 Mbps per carrier for the type of fixed and portable access

Wimax controversy in Indonesia

noreply@blogger.com (Mr_Oct) — Wed, 17 Mar 2010 02:00:00 +0000

Tender broadband wireless access (BWA) successfully held this year. WiMAX implementation was already in sight. However, one problem still prop. The government insists on using a version of WiMAX 802.16d, and 802.16e WiMAX industry request.

Each side filed reasons. The government says implementation of 'd' is nothing to win 'cake' economics of telecommunications operation. Meanwhile, industry players see the specification of 'e' is more friendly with keterkinian technology used in other countries. As is known, eight operators have been pocketing the BWA tender, namely Comtronics Systems Consortium and Adiwarta Perdania, Berca Hardayaperkasa, First Media, Telkom, Internux, Indosat Mega Media, Jasnita Telekomindo, and Wimax Consortium Indonesia.

As for its hardware device manufacturers supported Xirka, trg, and Hariff. To obtain certification, manufacturers must adopt a 40 percent local materials as stipulated in the provisions of Domestic Content Level (TKDN). The reason the government is very reasonable. According to the Director of Standardization Directorate of Post and Telecommunications (Postel), Ministry of Communication and Information (Depkominfo) Azhar Hashim, the telecommunications sector capital expenditure in 2006 reached Rp44 trillion.

Unfortunately, from this meganilai telecommunications, domestic industries have only a portion of 3 percent or Rp1, 2 trillion. Ironic indeed, the nation absorbed the foreign exchange abroad. Fatal, he added, in an area of local content, just the industry's capital expenditures, or 0.7 percent of Rp65 billion.

"The value is low. Keep right of the government policy to encourage local industry contribution even higher," he said some time ago.

However, if this reason is used to take advantage of DGPT 802.16d WiMAX, WiMAX Forum Chapter Chairman Sylvia W Sumarlin Indonesia argues if their aim is to protect domestic industries, the government must be consistent in terms TKDN. That way, foreign players have to hold a local company to meet the provisions of 40 percent local content.

"In addition to turn on the local industry, as well as technology transfer would happen," he said

"My company is selling the chipset to supportWiMAX 16d. Unfortunately it does not sell," added Chief Executive Officer of this Xirka.

Together trg and Hariff, before application Xirka support 16d. Why not sell, he explained, because many countries use WiMAX 16e. This is one of the factors that make 16d WiMAX chipset can not compete with the 16e. Not widely used because its market is limited, automatically from the price to be expensive. In contrast to the broad market 16e so that the high demand.

"Law of the economy, high demand so the production cost can be reduced. Receive the effects, even prices can be depressed," he said.

From the technology side, he continued, version of 'e' to adopt IPV6 Internet access. This is important, the article would be the world broadbandnya apply to IPV6. Where IPV6 used for large data transfers quickly. Meanwhile, versions of 'd' does not support this technology.

"Furthermore, WiMAX 802.16e is ready for international roaming. Do not forget, the Indonesian government through the Ministry of Communication and Information Tifatul Sembiring has signed agreements for international roaming with countries of Asia-Pacific recently in Bali," he said.

That be a problem, said Sylvia, APEC countries to adopt WiMAX 802.16e technology. So it is impossible for Indonesia international roaming can be realized.

"DG Postel still want 802.16d, but that does not mean they ignore 802.16e which is widely used in other countries, including developed countries. We are ready to produce," Sylvia added.

Sylvia also asked telecom operators not too worried about the presence of Wi-MAX. The reason internet mobile technology will not erode mobile voice. This was caused by different service segments. However, mobile internet technology could threaten the BWA berakses cellular industry because the price is very cheap and sophisticated. Thus, he stated, mobile actors to innovate.

Chairman of the Indonesian Telecommunications Society (Mastel) Setyanto P Santoso added, the telecommunications industry needs to adopt 802.16e in Indonesia is very urgent. The problem, many video applications data services, animation, and sound more sophisticated than the version 'd'.

"If the government seriously, we do not have to wait for the perfect research for technology transfer. The service I have seen also received resistance from the government," he said.

Wimax Forum-related complaints, the Head of Public Relations Depkominfo Gatot S Dewa Broto, asserted that the government strongly supports the BWA applications in the country. While persoalanpemilihan 802.16d, because the government wants to stimulate use of domestic products, while 802.16e is still 802.16m even internationally.

According to him, versions of 'e' instead of can not be used. Only, the government saw as the dominant industry is still using the 802.16d chipset. Tried to mediate, telecommunications practitioners argue Djiwatampu Arnold WiMAX 802.16e applications still require more time.

For now proposed, in Indonesia using technology 16d. If the technology is approved 16e, Arnold lamented wasted investment pocket for 2-3 years, primarily for research and development budget. 16d, which means the standard aliases remain nomadic, Arnold acknowledged the world has abandoned. Currently, practitioners are developing 16e and headed to the mobile Wimax. Wimax assessed as appropriate technology in order to realize broadband service in the city and countryside. As is known, the government is targeting in 2015 there were 50 million broadband users.

Through the internet literacy in remote areas, the government hopes the economy can be more motivated again. Therefore, people can increase sales through online system. In addition, can also access the latest technology to enhance their production.

Wimax in Indonesia

noreply@blogger.com (Mr_Oct) — Wed, 17 Mar 2010 01:49:00 +0000

In Indonesia, Wimax is not as popular as Wi-Fi (Wireless Fidelity). But as one state licensed Wimax (Worldwide Interoperability Mobile Access), Indonesia has the authority to apply this technology to the telecommunications operators who have a mobile readiness readiness both in infrastructure and operational readiness-maintanance. Wimax wireless broadband access are expected to provide fresh air in the midst of the telecommunications industry competition and market needs.

Little Review about Wimax

In the session the International Telecommunications Union (ITU) in June 2007, Wimax included in the IMT-2000 standard. The standards also known as the standard third-generation mobile telecommunications (3G) spectrum covering 2.5 to 2.69 Gigahertz.

Wimax is currently undergoing studies to ensure the coexistence of its status as one of the 3G technology. In fact, through his IMTAdvanced standard ITU, Wimax is ready to 4G technology.

Wimax in The Manufacturer or Provider

Head of General Affairs and Public Relations Directorate General of Post and Telecommunication, Gatot S. Dewa Broto confirmed, his party has prepared a draft set of rules Kominfo Regulation of the Minister for the tender BWA (broadband wireless access) which will begin in 2008. The tender is intended to support the equipment industry to license a frequency block in the 2.3 GHz band.

Wan Yi, Director of Wireless and Mobile Communications Department of China Standards Association (CCSA), said 3G Wimax satus will disturb the balance of the mobile industry.

"3G technology based on triangulated structure of W-CDMA, CDMA, and TD-SCDMA. Wimax will this affect the massive ririskiky. All the big vendors W-CDMA and CDMA against this, "said Wan. Wimax is a technology that uses SOFDMA techniques, multicarrier modulation technique that uses subchannelisasi. Providers using the standard frequency for fixed subscribers (fixed) and mobile (normadic). Wimax different modulation techniques with CDMA CDMA which uses different codes to each customer.

Wimax on the Consumer Side

Wimax technology can cover an area of about 50km, where hundreds of users will be shared signals and channels for data transmission up to 155 Mbps.

In mobile applications, user Wimax Wifi like using a terminal such as: notebooks, PDAs, and smartphones. Wimax utilization with the use of Wifi. A terminal can detect Wimax and Wifi network so that users will increasingly be facilitated for selecting Wimax broadband (Wimax network) or wireless hotspot (wifi network / Wireless LAN).

Synergy Wimax-Wifi-Cell

Wifi (Wireless LAN) is a wireless communication network through the LAN computer. Its scope is limited to certain areas, so-called hotspot. Services provided can vary, like LAN applications such as email, internet, intranet, messaging, music / video streaming and other IP service base.

When Wifi Wimax combined with the implementation will clearly accelerate and expand its use, more secure because it can be a QoS (Quality of Service), more reliable, and rich in new services.

Synergies between the mobile Wimax network combining wired and wireless, and terminal services. In general, the concept of convergence in telecommunications includes 3 aspects, namely: devices, services, and network.

Wimax generally introduced as offering access to multi-access solutions, for example: Wimax to complement the already existing networks (2G/3G and WiFi). The emergence of Wimax will automatically lead to competition with 3G bearers

3G service is mobile communication service that promises peningkakan bandwidth up to 384 Kbps when accessed on the move (normadic) while for the vehicle moving speed 128 Kbps and 2 Mbps sampao rest. GSM-based 3G technology (WCDMA) and CDMA (CDMA 2000). Thus the advantages of WiMAX is speed and services more attractive than 3G. However, the ability mobilitynya 3G is still superior because it uses the node B which of course could include a wider.

Condition:
You have installed Vista and now you want XP to be on the second boot, and when you do, your Vista is not detected anymore, so you have to choose between re-format your drive and then install it again, or you repair Vista and it does not matter.

But you can run both in a dual boot without having to reformat.
Seetlah your Vista install, you install XP as the drive x:> (x is the drive of your choice, it could be d:, e:, etc..)

After you restart the computer, boot to Vista it does not appear, do not worry.
Next please you boot from the CD / DVD Vista, select repair the installation, now booting from the Vista works, but XP does not boot up, do not worry once again.

Place the CD / DVD drive your Vista in Vista (after entering the desktop) and go to the Start Menu, All Programs, Accessories and right click on the Command Prompt and click on Run As Administrator

Now follow some of the following commands:

Use Bootsect.exe to restore (restore) the MBR and boot from the Vista code that transfers control to the Windows Boot Manager program. To do so, enter the following command at the command prompt:

Drive: \ boot \ Bootsect.exe-NT60 All

In this command, Drive is the drive where the installation media is Windows Vista.

Use Bcdedit.exe to manually create entries in the BCD Boot.ini file for the earlier versions of OS Windows. To do so, enter the following command at the command prompt.

Note that you need to look at it again in the following command is that the Drive is the drive where Windows Vista installed.

Drive: \ Windows \ system32 \ bcdedit-create (NTLDR)-d "Description for earlier Windows version"

Note that the words "Description for earlier Windows version" you can change the text or any text. For example, you write it with "Windows XP" or "Windows Server 2003"

Drive: \ Windows \ system32 \ bcdedit-set (NTLDR) device partition = x:

Note that x: is the drive letter for the active partition.

Drive: \ Windows \ system32 \ bcdedit-set (NTLDR) path \ ntldrDrive: \ Windows \ system32 \ bcdedit-displayorder (NTLDR)

Restart your computer.

Good luck!
