The document summarizes the IEEE 802.20 standard for mobile broadband wireless access. Key points include: - IEEE 802.20 defines the PHY and MAC layers for mobile broadband networks to provide data rates over 1 Mbps with support for vehicular mobility. - It aims to fill the gap between cellular and wireless local area networks by providing greater coverage and mobility than WiFi but with higher data rates than 2G and 3G cellular networks. - The standard supports applications requiring high-speed data access like video and VoIP through efficient packet-based transmission optimized for IP services. It also defines enhancements for conformance testing, system performance, management information, and bridging of 802.20 networks.
