Next Generation Wireless Broadband

802.16m (WiMax 2), 802.22 (Wireless Regional Area Networks), LTE (Long-Term Evolution), and LTE-Advanced are emerging broadband wireless standards that offer many powerful wireless features. 802.16m and LTE-Advanced promise data rates of 100 Mbit/sec in the mobile environment and 1 Gbit/sec in the fixed environment, supporting mobility speeds of up to 500 km/hr. 802.22 is the first two-way wireless standard that employs the TV bands, facilitating deployments in remote and sparsely populated areas, thus helping bridge the digital divide. This tutorial aims to provide the participant with a strong foundation on these standards, as well as new digital TV standards and public 802.11 networks. Topics covered include the physical (PHY) layer, adaptive modulation and coding, OFDMA, SC-FDMA, multiple antenna systems, medium access control (MAC), TDD and FDD transmission, and the frame formats. It also provides two case studies on wireless relay and co-operative networks (with emphasis on 802.11s and 802.16j) and on improving cell edge performance for OFDMA networks.
