Beyond 4G

Source: Telecoms December 2, 2009 Written by James Middleton WiMAX chipset vendor Beceem Communications has unveiled a number of uplink performance improvements to its portfolio of 4G chips. The 4G Turbo improvements may appear in any WiMAX network as they work with every Wave 2-compliant WiMAX base station, the company said, enhancing network coverage and user experience, especially at the cell edge and in areas of low signal strength. The improvements provide Dual Antenna Transmit diversity for maximum uplink performance under all signal conditions and deliver a gain of approximately 2dB compared to other WiMAX products, Beceem claims.

The joint initiative will look at the deployment of the Android operating system on smartphones delivering VoIP over WiMAX and other IP-based communications capabilities. D2 provided its mCUE converged communications client paired with Beceem’s high performance BCSM250 WiMAX modem and deployed on WiMAX-enabled smartphones and MIDs such as the ECS T371. In early November, D2 and Beceem completed what they claim to be the world’s first mobile VoIP calls over WiMAX on Android using the Zoom OMAP34x-II mobile development platform (MDP) and a Beceem BSCM250 WiMAX modem with D2’s kernel-level embedded voice engine.

Cambridge Consultants has launched DUEL (Dual-domain Uplink Equaliser for LTE), a platform that the company says will significantly improve LTE uplink performance when compared to MMSE, the "text-book" receiver design. DUEL, designed as an algorithmic and DSP extension to LTE base station receiver designs, requires no changes to handsets. Cambridge Consultants' patent pending DUEL receiver take advantage of properties of the LTE uplink signal to reconstruct what was transmitted with higher fidelity than a conventional text-book receiver. As a result, it works well even when the signals received by each BS antenna are highly correlated. Read full article...

Source: Cellular News Over the last several years, mobile WiMAX has moved through standardization, productization, and interoperability testing and certification. Larger-scale network deployments are finally becoming a reality. Clearwire in the United States has already declared 173,000 subscribers, Yota in Russia has been growing at a decent rate reaching 100,000 subscribers in August and 200,000 in October, and PacketOne in Malaysia has reached 130,000 subscribers. UQ Communications once expected to reach 300,000 subscribers by the end of 2009, but is behind schedule in its rollout and will fall short of that initial target. South Korea has seen KT's and SKT's subscriber numbers remain fairly stagnant, while these service providers prepare for another big push as a third WiMAX service provider comes to South Korea. This handful of WiMAX service providers alone will account for a significant minority of the nearly two million mobile WiMAX subscribers expected by the end ...

Source: ZDNET China's TD-LTE standard is unlikely to face the same obstacles that plagued the country's earlier mobile wireless standard, TD-SCDMA, industry analysts say. China in October submitted TD-LTE specifications to the International Telecommunication Union (ITU) for approval as a 4G standard. If ratified, it will be officially recognized by the ITU as a 4G technology in October 2010, according to reports. While the country's 3G predecessor, TD-SCDMA, got off to a bumpy start, dogged by technical issues and a lack of device variety, industry watchers are expecting TD-LTE to fare better. Julian Bright, Informa telecoms and media analyst told ZDNet Asia that TD-LTE, as a variant of FDD-LTE (Frequency Division Duplex LTE), is technically similar to the global LTE standard meant for markets where TDD spectrum is more readily available. As such, "strictly speaking, TD-LTE is not a new 4G standard", he said. In comparison, TD-SCDMA was developed largely for...

Source: Heavy Reading Long Term Evolution (LTE) core network activity is heating up as many vendors look to seize a share of the next-generation packet core market, according to a new Heavy Reading report. The pursuit of the Evolved Packet Core (EPC) is picking up pace now because of the strategic significance of these packet core products for many vendors, and not necessarily because of the potential market size. The packet core will be among the fastest growing segments in wireless infrastructure, growing at a rate of 10 percent per year for the next five years, and will be worth $2 billion in 2012, according to the report, "Evolved Packet Core for LTE: Market Forecast & Competitive Analysis." Ericsson AB (Nasdaq: ERIC) and Nokia Siemens Networks are the undisputed market leaders in the packet core market. In 2008, the 3GPP packet core market was worth $1.2 billion, and these two vendors had nearly 70 percent of the market, according to Heavy Reading. Hot on th...

Amid concerns that India’ auction of 3G spectrum may be delayed yet again, the WiMAX Forum has said that every six months of delay in the process results in $1bn in lost revenues for the country. The latest official date given for the auction is January 2010, but after numerous delays this may be postponed yet again. But industry body the WiMAX Forum is also calling for the government to separately release spectrum for WiMAX deployments in the 2.3/2.5 GHz frequency bands in a bid to stimulate broadband growth and economic development immediately. ”WiMAX auctions should be done well ahead by de-linking the auction from the 3G auction process as the country needs broadband growth and wireless high speed Internet access now for the economic development of the Indian society,” said Ron Resnick, president and chairman of the WiMAX Forum. “India needs immediate and affordable broadband access to meet the aspirations and expectations of the younger generation who constitute 56 per cent ...

Mexico's MVS Comunicaciones is reported to have secured an agreement with US based Clearwire to deploy a WiMAX network covering 23 Mexican cities. The roll out is expected to start in the second half of next year, with a launch some time in the fourth-quarter. The deployment is however dependent on the Communications and Transportation Ministry renewing the company's existing spectrum holdings in eight of the planned 23 cities. Clearwire is a minority shareholder in MVS, and the project is separate from the US network deployment. The Mexican firm is now seeking to raise around US$700 million to fund its infrastructure rollout. In related news, MVS's founder, Joaquín Vargas Gómez died over the weekend after a long illness. In a statement, the Mexican President said "Mexico loses a businessman who contributed to the development of radio, a means of communication that is now a clear expression of Mexico's democratic vitality."
