Wireless Bridge:
The first use of the WDS, Wireless Bridge mode is to create the wireless bridge between two or
more wired networks, for example networks in different buildings with no wired connections between
them. All APs in a WDS have to be configured for the same radio channel and must be configured
with their WDS partner AP BSSIDs (MAC addresses). The data being transported is bridged
transparently; i.e., the data received by the LAN station is identical to data that would be received if
both LAN stations had been connected to the same LAN subnet.
Antenna Diversity
The P-520r Operator Access Point uses antenna diversity to select the best reception signal at the two
integrated antennas. Antenna diversity counters the adverse effects of multi-path fading and antenna
pattern nulls and reduces the packet error rate.
The main antenna (at internal connector J4) is used for transmission whereas both antennas, main
and aux, can receiving signals. Receive diversity examines only packets directed at the AP. A count
of frames received consecutively with FCS errors is compared to the configured threshold value.
When this value is reached, the receive antenna used is switched to the other antenna. If a directed
frame is received without errors the error count is reset back to zero.
