Ultra-Wide Band (UWB) is a promising physical layer technology which potentially enables low power and high rate devices with applications for Wireless Personal Area Networks (WPANs) and for Wireless Body Area Networks (WBANs). The UWB technology considered in this paper, called MultiBand UWB, is based on Orthogonal Frequency Division Multiplexing (OFDM). Any physical layer technology requires a Medium Access Control (MAC) protocol to be coupled with. This paper focuses on a distributed Time Division Multiple Access (TDMA) MAC protocol to support high data rate applications, developed within the WiMedia Alliance [1].The aim of this paper is to study the dynamic beacon period extension and contraction when a newcomer device joins a existing beacon group (BG) and to evaluate the related energy consumption.

This paper presents an implementation example for placing Bluetooth (BT) host protocol over the WiMedia Ultra WideBand (UWB) Physical (PHY) and Medium Access Control (MAC) layers. The adaptation layer is operating below the Bluetooth Host Controller Interface (HCI), hence offering a host interface identical to Bluetooth towards the host. Some points have been identified for Bluetooth and WiMedia multimode operation, where further specification effort is needed.
