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.

POINT-TO-POINT CONFIGURATION

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).

POINT-TO-MULTIPOINT CONFIGURATION

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.
