›› Abstract

Since Federal Communications Commission (FCC) approved the use of UWB(Ultrawide Band) on an unlicensed basis in 2002, UWB has been expected to replace high-speed cable and enable a number of brand new applications such as multiple High Definition (HD) or uncompressed video streaming and location-aware devices in the indoor and outdoor environment. It is envisioned that UWB will be prevalently used in many consumer electronics and computing devices because of its low power operation and support for high speed within personal area.

In this talk, the physical characteristics and the eco-system of wireless networks based upon UWB will be presented. The focus will be given to Multi-Band OFDM UWB, and the architecture of Wireless USB and WiMedia standards based upon MB-OFDM will be overviewed. WiMedia MAC (ECMA 368) designs for UWB systems will be presented. Finally, the merits of UWB as the enabling technology for location-aware applications will be discussed.
