MAC principles for an ultra wide band wireless access

Ultra wide band (UWB) radio is becoming a promising field for the design of new digital communication systems. This technique, mainly based on the impulse radio paradigm, offers great flexibility and enormous potentiality in view of a broadband wireless access. This paper presents the main principles for the development of a multi-access scheme based on UWB. The principles for the definition of a distributed medium access control for mobile computing applications are described as well as the detailed functional model involved in the capacity-sharing procedures.
