Abstract
A transmitting device comprises a plurality of distributed transceivers, a baseband processor and a network management engine. Data streams are generated at baseband by the baseband processor. Diversity coding such as space-time coding may be performed over the generated data streams in the baseband. The transmitting device concurrently transmits each of the coded streams in a same radio frequency (RF) band to a receiving device over the entire distributed transceivers through associated antennas. When needed, the network management engine may identify one or more auxiliary devices providing available transceivers and antenna beamformers to the transmitting device for sharing. Beam patterns and antenna orientations may be determined for associated antennas of the available transceivers for the transmitting device. Each of the coded data streams in the same radio frequency band may be transmitted to the receiving device over the entire available transceivers for the transmitting device through the associated antennas.
