Abstract

The WiMedia Alliance is undertaking the development of an UWB-based system specification with participation from more than 170 companies. UWB technology will provide data rates up to 480 Mb/s within a range of up to 10 m. High-rate UWB will enable fast download of content from one consumer electronic (CE) device to the next in seconds instead of minutes or longer. In addition, the low-power characteristic of UWB will make possible the ubiquitous use of this technology in portable and mobile CE devices, such as cameras, MP3 players, and CD players. The WiMedia Alliance is specifying the physical layer, the MAC sublayer, and convergence layers. The WiMedia PHY layer is based on multiband orthogonal frequency-division multiplexing. The WiMedia MAC is completely distributed, making it an excellent candidate not only for the aforementioned UWB applications, but also for the next-generation MAC protocols in the domain of cognitive radios as well as in cooperative communications
