With the pending release of WiMax 2.0 come s a dual-mode GSM-WiMax phone, as reported by Peter Sayer of PC World
Russian WiMax operator Yota will soon begin offering its customers a WiMax terminal that can make VOIP calls — and hand them over to a GSM network when the caller wanders out of the WiMax coverage area.
During the international ITU World Telecoms Fair 2009 in Geneva, Yota and their partner Samsung, debuted their prototype and announced that they have commenced testing of the next version of mobile WiMAX technology: Release 2.0 (IEEE 802.16m standard). Both Yota and Samsung expect it to operate up to four times faster than the current generation of WiMax products, which are based on the IEEE 802.16e standard.The WiMax Forum offers a little more detail:
The IEEE’s IMT-Advanced proposal documents that … using 4X2 MIMO in the urban microcell scenario with only a single 20 MHz TDD channel available system wide, the 802.16m system can support both 120 Mbit/s downlink and 60 Mbit/s uplink per site simultaneously. Higher data rates can be obtained with additional spectrum resources or more complex antenna schemes. The WiMAX Release 2 profile will also incorporate these capabilities for improved VoIP capacity, spectral efficiency, latency, handover speed, cell range, and coverage, with support for wider operating bandwidth in both TDD and FDD duplexing.
The firm plans to start installing WiMAX Release 2.0 solutions from Samsung across its network by the end of 2010. Yegor Ivanov, Yota’s director of business development said that they hope to offer service in 180 Russian cities with a population of over 100,000 by the end of 2012. Yota will install around 20 base stations in each city, depending on the terrain, and aims to sign up around 5 percent of the population within its coverage area.
