This project is part of a co-ordinated project, ULTRA-MED, which goal is to develop a low rate wireless personal area network (LR-WPAN) based on Ultra Wide Band (UWB) technology and its application to the monitoring and tracking of home hospitalised patients.
The particular goal of the subproject focuses on the study of wireless communication techniques dealing with synchronisation, transceiver architecture design and media access control mechanisms.
The other main issue to be addressed in ULTRA-RED deals with the cooperative organisation of the WPAN, which makes necessary the definition of a media access control method that is robust, self-configurable, minimises power consumption and allows the coexistence of several networks that share the same features.
