Formed in December, 2002, the IEEE 802.20 working group has as its mission: To develop the specification for an efficient packet based air interface that is optimized for the transport of IP based services. The goal is to enable worldwide deployment of affordable, ubiquitous, always-on and interoperable multi-vendor mobile broadband wireless access networks that meet the needs of business and residential end user markets. Specification of physical and medium access control layers of an air interface for interoperable mobile broadband wireless access systems, operating in licensed bands below 3.5 GHz, optimized for IP-data transport, with peak data rates per user in excess of 1 Mbps. It supports various vehicular mobility classes up to 250 Km/h in a MAN environment and targets spectral efficiencies, sustained user data rates and numbers of active users that are all significantly higher than achieved by existing mobile systems. The 802.20 interface seeks to boost real-time data transmission rates in wireless metropolitan area networks to speeds that rival DSL and cable connections (1Mbps or more) based on cell ranges of up to 15 kilometers or more, and it plans to deliver those rates to mobile users even when they are traveling at speeds up to 250 kilometers per hour (155 miles per hour). This would, for example, make 802.20 an option for deployment in high-speed trains.

The 802.22 WRAN (Wireless Regional Area Network) Working Group standards relate to the reuse of otherwise unused UHF television broadcast channels for Wi-Fi-like communication. This allows close to a 40-mile radius of coverage, including inside buildings, from a single transmitter. Bandwidth in the 700 MHz spectrum was auctioned in January 2008 with Verizon, AT&T and Qualcomm being major winners.
