The IEEE 802.16m standard is the core technology for the proposed Mobile WiMAX Release 2, which enables more efficient, faster, and more converged data communications The 802.16m system can support both 120 Mbit/s downlink and 60 Mbit/s uplink per site simultaneously and has a mximum speed of 300 Mbit/second downlink. It will be about twice as fast as Wimax. The goal for the long-term evolution of WiMAX is to achieve 100 Mbit/s mobile and 1 Gbit/s fixed-nomadic bandwidth as set by ITU for 4G NGMN. WiMAX 2 technology, according to Alvarion, Beceem, GCT Semiconductor, Intel, Motorola, Samsung, Sequans, XRONet and ZTE, will provide 300-Mbits of throughput, with less latency and more bandwidth available for applications like VOIP calls.
The group will issue detailed milestones and delivery schedules within the next three to six months, with an eye toward certifying the first commercial products in mid-2011. WiMAX’s chief proponents have been Clearwire and Sprint, which have been busy covering major U.S. cities with the 802.16e wireless WiMAX technology. An important aspect is that Wimax companies do not cap usage. Head to head comparisons generally show faster downloads with WiMax versus 3G and LTE.
LTE Advanced promises faster speeds LTE Advanced is expected to be released in 2011.
