A New Class of Adaptive Wireless Push Systems Using Multiple Smart Antennas

Data broadcasting has emerged as an efficient way of delivering information over asymmetric wireless environments. Push systems are able to provide high scalability and client hardware simplicity in such environments. This paper proposes the use of multiple smart antennas to increase the performance of an adaptive wireless push system in environments characterized by locality of demand. Simulation results reveal that the use of smart antennas suffices a significant performance increase over the use of static directional antennas. This is achieved because of the ability of smart antennas to alter their beamwidth and thus, to succeed an efficient coverage of the area where they broadcast.
