Abstract:
In a wireless communication system having a plurality of directional antennas associated with a first communication device at a first site, a router for targeting a destination via an indeterminate path including said first site, at least one second wireless communication device at a second site, a method for selecting a best antenna from said plurality of directional antennas for said first wireless communication device for communicating with each said second wireless communication device, the method comprising:causing said first communication device to broadcast packets, via each said directional antenna, to query for existence of said second wireless communication devices; receiving a plurality of information packets about existence of said second wireless communication devices in response to said broadcast packets or in response to a query about third parties; thereafter as between each said directional antenna and each second wireless communication device, determining a packet success metric for each said directional antenna; comparing packet success metrics with each other to determine a best match of directional antenna with each second wireless communication device; and storing at said first site said best match such that said router is able to request communication through said first device with said destination via said second wireless communication device without knowledge of said match.
