New indoor high-speed radio communication system

We propose a new concept for indoor high-speed radio communication includes a no-wiring relay station (RS) on the ceiling. The concept offers very simple set up procedures, and flexibility in composing and adjusting radio zones. We introduce a prototype of the RS, which operates using the voltage supplied to standard fluorescent sockets. Planar multibeam and pencil-beam array antennas for the RS are designed by using an improved indoor propagation delay simulation algorithm.
