Abstract:
1. An apparatus for enhancing operation of wireless network environment, comprising a plurality of directional antennas oriented about an axis, wherein the plurality of directional antennas have substantially non-overlapping patterns relative to each other, wherein the peak gains of the plurality of directional antennas are oriented radially and outwardly about the axis and offset relative to each other at an angle substantially equal to 360/N, where N is the number of directional antennas in the plurality of directional antennas; wherein the plurality of directional antennas are each operative to transduce a radio frequency signal and provide an output signal corresponding to the radio frequency signal; a switch operatively connected to the plurality of antennas and operative to switch between the antennas in response to control signals; a detector operative to detect at least one signal attribute of the output signals provided by the directional antennas; and an antenna selection module operative, during receipt of the preamble of a wireless frame, to
