Bridge Link Topologies
The IEEE 802.11 standard defines a WIreless Distribution System (WDS) for bridge
connections between BSS areas (access points). The outdoor wireless bridge uses
WDS to forward traffic on links between units. Up to 16 WDS links can be specified
for a OAP6626A unit configured as a “Master” in the wireless bridge network.
OAP6626A slave units support only one WDS link, which must be to the network’s
master unit.
The OAP6626A support WDS bridge links on either the 5 GHz (802.11a) or 2.4 GHz
(802.11b/g) bands and can be used with various external antennas to offer flexible
deployment options.
Note:
The external antennas offer longer range options using the 5 GHz radio, which
makes this interface more suitable for bridge links. The 2.4 GHz radio has only the
8 dBi omnidirectional antenna option, which is better suited for local access point
services.
When using WDS on a radio band, only wireless bridge units can associate to each
other. Wireless clients can only associate with the wireless bridge using a radio band
set to access point mode.
Point-to-Point Configuration
Two OAP6626A 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 OAP6626A configured as a “Master” wireless bridge can use an omnidirectional or
sector antenna to connect to as many as 16 bridges in a point-to-multipoint
configuration. There can only be one OAP6626A “Master” unit in the wireless bridge
network, all other bridges must be OAP6626A “Slave” units.
Using the 5 GHz 8 dBi omnidirectional external antenna, the Master unit can
connect to Slave units up to 3.3 km (2 miles) away. Using the 13.5 dBi 120-degree
sector antenna, the Master can connect to Slave units up to 10.3 km (6.4 miles)
away.
