Abstract
A wireless radio communication scheme in which data packets scheduled for transmission to spatially diverse locations are directed by a switched router apparatus capable of switching data packets and transmitting them between network nodes, where the direction and timing of switching is controlled in real time by the information derived from the packet's route destination and the network's node spatial topology. The present invention uses a very high speed electronically controlled switched array feed for the microwave frequency range above 1 GHz, coupled to an RF focusing and collimating antenna that enables the wireless transceivers nodes to spatially switch data packets towards other wireless transceivers nodes based on the data packets routing, scheduling and link availability information.
