Abstract

Methods and devices related to wireless networking. A wireless device has multiple directional antennas and multiple backhaul radio modules which provide point to point wireless links with other wireless devices. Each radio module can use any one of the available directional antennas to link to one other routing device. Antennas are automatically selected for each wireless device by merely setting one device in a “hunt” mode and setting another device in a “listen” mode. Devices in a hunt mode cycle through the available antennas by sequentially transmitting transmit messages to devices in the listen mode using each of the available antennas in turn. Devices in the listen mode also cycle through their available antennas by sequentially “listening” for transmit messages. A listen mode device, receives transmit messages on each of its available antennas, and, after gathering the relevant data, determines which of its antennas is best suited for communicating with the hunt mode device. The listen mode device antenna which is best suited is then used to transmit a response message to the hunt mode device. This listen mode device antenna is thus configured for communicating with the hun…
