Abstract

WiMedia Alliance has worked on the UWB-based system specification and has published the WiMedia specification for MAC, PHY, and MAC-PHY Interface. These specifications are further standardized in ECMA TC48 and are published as ECMA-368 --- High Rate Ultra Wideband PHY and MAC Standard, and ECMA-369 --- MAC-PHY Interface for ECMA-368. The standard specifies a personal area network air interface utilizing OFDM based PHY providing up to 480Mbps, and distributed controlled MAC mechanisms. This paper introduces the technology overview of WiMedia MAC and the MAC LSI design challenges. This MAC LSI is intended to offer a generic communication platform to meet various application needs, and was certified to be compliant to the specification by WiMedia. The MAC design includes not only standardized protocol set, but also some additional enhancement features to achieve better performance or to meet certain application requirements.
