Market Opportunities for WiMAx, 802.20 & UMTS TDD technologies
The SkyWeb team, who has been offering GPRS wireless data service since 2003, will deploy a UMTS TDD system to offer mobile wireless broadband to businesses and consumers.
The Finland decision follows recent news in Japan, another advanced wireless market, that IPMobile, a Japanese broadband wireless services company, has submitted its application to deploy a UMTS TDD system in the same 2010 MHz spectrum which was recently allocated by the Japanese regulator exclusively for UMTS TDD use.
The solution leverages a number of new options such as transmit diversity to maximize non-line-of-sight coverage and lower initial capital expense for operators, offering a similar coverage to UMTS TDD products in the lower frequency bands.
The modem is powered by the IPWireless UMTS TDD ASIC, which enables the modem's exceptional performance and low power requirements at a low cost.
Dual mode terminals are still quite expensive, and UMTS TDD handsets will not be available until 2006.
The company is aiming to maximize the value of its UMTS licence by using UMTS TDD technology operating in its "unpaired" 1.9 GHz UMTS spectrum, meaning that it would be capable of delivering peak sector speeds of up to 4.5 MB/s.
New Zealand-based mobile broadband service provider Woosh Wireless has announced that it has placed an order for 180 additional UMTS TDD base stations from network equipment provider IPWireless, in order to expand its network.
Woosh became the first company in New Zealand to deploy a major commercial UMTS TDD network in 2003, and has recently announced that it has now gained over 10,000 subscribers in its initial markets.
The mobile handset will allow UMTS TDD network operators to offer carrier-grade mobile voice over IP (VoIP) services, in addition to existing broadband and other packet based services, on their converged networks, claim the companies.
The UMTS TDD VoIP handset will reportedly use Atmel's AT76C902 VoIP system-on-a-chip as the main processor, with the IPWireless TDD Module performing the UMTS TDD modem functions.
Broadband wireless technology solutions provider IPWireless has announced the immediate availability of a number of dual-band devices that enable global roaming across UMTS TDD networks.
