The wireless bridge modes connect two or more wired networks, for example
networks in different buildings with no wired connections. You will need a 3Com
Outdoor 11a Building to Building Bridge and 11bg Access Point unit on both
sides of the connection. The wireless bridge can connect up to six remote
networks.
When using bridge mode on a radio band, only wireless bridge units can
associate to each other. Wireless clients can only associate with the unit using a
radio band set to access point mode.

ONFIGURATION
Two bridges can form a wireless point-to-point link using their 5 GHz (802.11a)
integrated antennas. A point-to-point configuration can provide a limited data
rate (6 Mbps) link over a long range (up to 15.4 km), or a high data rate (108
Mbps) over a short range (1.3 km).

A wireless bridge set to “Master” mode can use an omnidirectional antenna to
connect to as many as six bridges in a point-to-multipoint configuration. There
can only be one “Master” unit in the wireless bridge network, all other bridges
must be set as “Slave” units.
The following figure shows a point-to-multipoint “star” configuration with one
bridge set to “Master” and using an omnidirectional antenna.
