IEEE 802.20 or Mobile Broadband Wireless Access (MBWA) Working Group, the establishment of which was approved by IEEE Standards Board on December 11, 2002, aims to prepare a formal specification for a packed-based air interface designed for IP-based services.
It is hoped that such an interface will allow the creation of low-cost always-on broadband wireless networkss.
The group will specify physical and medium access control layers of the air interface, operating in bands below 3.5 GHz and allowing the users to transmit data with a peak data rate of over 1Mbps.
