A throughput evaluation for UWB system considering performance of a PHY prototype

Abstract

UWB is a short range (up to 10m) wireless communication technology which provides high throughput with low transmission and high reliability. We developed a PHY prototype conformed to ECMA-368, one of UWB standards, and a network simulator for evaluating MAC throughput of ECMA-368. In this paper, we propose an evaluation method considering the characteristic of PHY, the channel model and the propagation loss derived from our PHY prototype. This enables throughput evaluation in various usage models. The evaluation result shows that an application that needed 200 Mbps throughput is available at range up to 2 m. The throughput is enough to transmit a HDTV stream about 50 Mbps up to about 6 m and to transmit two HDTV streams within 3 m.
