Ultra-wideband as a Short-Range, Ultra-High-Speed Wireless Communications Technology
Aug 1, 2004
By Ibrahim Haroun, T. Kenny and R. Hafez Ultra-wideband technologies have been proposed to provide ultra-high speed data rates for short-range communications. In the United States, the systems have been approved for use in the frequency band 3.1 GHz to 10.6 GHz. It supports bit rate greater than 100 Mbps within a 10-meter radius. UWB
communications coexist with other wireless networking standards such as 802.11 LAN, 802.16 MAN and WAN....
Using picocells to build high-throughput 802.11 networks
Jul 1, 2004
By Gregory Davi In a typical indoor 802.11 wireless network, a single access point can cover
2500 to 10,000 square feet. Picocells are substantially smaller RF coverage
areas and are used to provide high data throughput for dense wireless
terminals/appliances by minimizing the amount of bandwidth that is shared
among wireless users....
