Abstract
A system is disclosed with a first transceiver configured to communicate with a second transceiver. The first transceiver includes a message encoded by a spreading code and a transmitter configured to use beam forming to send the message as a beamformed transmit message to the second transceiver in one of multiple regions repeatedly targeted by the beam forming. The transceivers include a receiver configured to operating without beam forming in receiving to decode the message using the spreading code with a spreading length to compensate for the lack of beam forming. Other embodiments may include an integrated circuit with a processor operating a transmitter and a receiver of the first or the second transceiver. The integrated circuit may act as a central point, a base station and/or an access point communicating with a client, or operate the transceiver as the client, a station or as a cellular phone.
