<p>A method and apparatus to facilitate directional proximity detection by a wireless device. In one embodiment of the invention, the wireless device has a phased array antenna system that facilitates the directional detection of other wireless device(s). For example, in one embodiment of the invention, the phased array antenna system of the wireless device uses a radiation pattern beam that circumrotates the wireless device to detect the proximity and location of other wireless devices. In another example, in one embodiment of the invention, the wireless device uses a search strategy to optimize the process to detect the proximity and location of other wireless devices. The search strategy may adjust the radiation pattern beam to any desired angle to detect the proximity and location of other wireless devices.</p> |
