Abstract: Aspects of a method and system for optimal beamforming in a wireless network are presented. Aspects of the system may include one or more processors for use in a requesting communication device wherein the one or more processors may be operable to request a transmission time slot allocation. A determination may be made by a coordinating communication device as whether to assign a sector transmission time slot and/or beamforming transmission time slot to the requesting communication device based on the transmission time slot allocation request. The one or more processors may be operable to receive the assigned sector transmission time slot and/or beamforming transmission time slot.

Abstract: A technique to identify that a station is capable of transmitting a PHY-BRP packet for use in training a directional antenna. The PHY-BRP packet is transmitted, when requested to do so, by appending the PHY-BRP packet to a BRP-Response in order to associate source and destination information to the PHY-BRP packet.

Abstract: Provided is dual mode operation by a communicating device in wireless network. The communicating device selects a radio frequency (RF) channel and a physical layer type. The communicating device processes signals received via the selected RF channel based on the selected physical layer type. The communicating device may determine whether a beacon frame has been detected base on the signals that were received via the selected RF channel and processed based on the selected physical layer type. When a frame is not detected, the communicating device may determine a signal energy level for the received signals. The communicating device may establish an association with an existing network based on detection of the beacon frame or the communicating device may transmit an originating beacon frame based on the determined signal energy level.
