Abstract
Enhanced wireless speeds are obtained using multiple transmission beams. In one example, a transmitter has a signal processor to receive a plurality of data streams, a plurality of analog converters each coupled to the signal processor to receive the plurality of data streams from the signal processor and to modulate the data streams onto carrier waves, and a plurality of phase shifters each coupled to an analog converter to each receive a modulated stream. A first antenna is coupled to more than one of the plurality of phase shifters to receive the modulated data stream from each phase shifter and transmit it on its respective carrier wave, and a second antenna is coupled to receive at least one modulated data stream and transmit it on its respective carrier wave.
