diversity antenna and receiver

AP (Access Point)s have two antennas. Receive diversity refers to the ability of the AP to provide better service to a device by receiving from the user on whichever of the two antennaes is receiving the cleanest signal. Transmit diversity refers to the ability of the AP to use its two antennas to transmit on a specific antenna only, or on a alternate antennas. The antennas are called diversity antennas because of this capability of the pair.
