Enhancement: Enhancements In WiMAX

WiMAX & IMT-Advanced

IMT-Advanced, also known as “systems beyond IMT-2000” is expected to offer constant higher data rates with high mobility to assure likely growing need for mobile WiMAX services that goes beyond what IMT-2000 can afford to provide. IMT- Advanced is awaiting technology that will require 3 to 5 years in the future with target maximum data rates, for research and examination, of up to 100 Mbits/sec in high mobility applications and up to 1 Gbit/sec in low mobility or nomadic applications. The capacity expected by IMT-Advanced is often referred to as 4G. It is commonly acknowledged that Orthogonal Frequency Division Multiple Access (OFDMA) technology will be integrated in IMT-Advanced in near future to get more the maximum benefits from the WiMAX.

“IMT-Advanced is a continuing effort. The full criteria, being extended within ITU-R Working Party 8F, are not expected until 2008. The specification of IMT-Advanced technologies will probably not be completed until at least 2010. In preparation for IMT-Advanced, the IEEE 802.16 Working Group has moved to initiate a new project designated as “802.16m” with the intent of developing enhancements to IEEE STD 802.16 to ensure suitability as an IMT-Advanced proposal”.  (WiMAX Forum)
