What is 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 (OFDM) 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)
