Global WiMAX network deployments surpass 500
GENEVA – October 6, 2009 – The WiMAX Forum® and executives from premier suppliers and operators were on hand during ITU Telecom World 2009 to express their commitment to build and trial WiMAX Release 2 based on the IEEE 802.16m standard. Ecosystem participants represented Alvarion, Beceem, Cisco, Clearwire, Huawei, Intel, KT, Samsung, UQC, Yota and ZTE. Also revealed was a milestone of 500 network deployments in more than 145 countries – placing WiMAX as the leading mobile broadband technology.
The WiMAX Forum, along with 50 companies, announced the endorsement of IEEE’s submission to ITU-R that proposes an IEEE 802.16m-based candidate for IMT-Advanced. The WiMAX Forum also announced that it will finalize its WiMAX Release 2 specification in parallel with IEEE 802.16m and IMT-Advanced, ensuring that WiMAX Release 2 networks and devices will remain backward compatible with legacy WiMAX Release 1 based on IEEE 802.16e.
The developing 802.16m standard offers new capabilities and efficiencies to meet the challenging IMT-Advanced requirements. The IEEE's IMT-Advanced proposal documents that, according to the ITU-R's rigorous definition reflecting aggregate throughput delivered to multiple users in a practical deployment, 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. This is breakthrough performance. 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 WiMAX Forum expects to see WiMAX Release 2 available commercially in the 2011-2012 timeframe.
