Enhanced wireless data rates using multiple beams
Enhanced wireless speeds are obtained using multiple transmission beams. In one example a transmitter sends data packets through an antenna array using multiple spatial beams and a plurality of analog converters. A receiver receives feedback from a remote station, the feedback including a quality measure of data packets received from the transmitter. A processor to controls transmission parameters of the transmitter using the feedback, the processor having a plurality of states, in a first channel analysis state, the processor determining a beam-forming vector for the antenna array, in a second beam search and training state, the processor determining pre-coding coefficients for the data packets, and in a third high rate transmission state, the processor providing pre-coded data packets to the transmitter for transmission, wherein the processor transitions from the third state to the first state upon receiving a reduced quality measure from the remote station.
