In normal mode, the wireless bridge provides a channel bandwidth of 20
Note:
MHz, and supports the maximum number of channels permitted by local
regulations (e.g., 11 channels for the United States). In Turbo Mode, the
channel bandwidth is increased to 40 MHz to support the increased data
rate. However, this reduces the number of channels supported (e.g., 5
channels for the United States).
Radio Channel – The radio channel that the wireless bridge
uses to communicate with wireless clients. When multiple
wireless bridges are deployed in the same area, set the
channel on neighboring wireless bridges at least four channels
apart to avoid interference with each other. For example, in the
United States you can deploy up to four wireless bridges in the
same area (e.g., channels 36, 56, 149, 165). Also note that the
channel for wireless clients is automatically set to the same as
that used by the wireless bridge to which it is linked. (Default:
Channel 60 for normal mode, and channel 42 for Turbo mode)
Auto Channel Select – Enables the wireless bridge to
automatically select an unoccupied radio channel. (Default:
Enabled)
Transmit Power – Adjusts the power of the radio signals
transmitted from the wireless bridge. The higher the
transmission power, the farther the transmission range. Power
selection is not just a trade off between coverage area and
maximum supported clients. You also have to ensure that
high-power signals do not interfere with the operation of other
radio devices in the service area. (Options: 100%, 50%, 25%, 12%, minimum;
Default: 100%)
Maximum Supported Rate – The maximum data rate at which the access point
transmits unicast packets on the wireless interface. The maximum transmission
distance is affected by the data rate. The lower the data rate, the longer the
transmission distance.
(Options: 54, 48, 36, 24, 18, 12, 9, 6 Mbps; Default: 54 Mbps)
Beacon Interval – The rate at which beacon signals are transmitted from the
wireless bridge. The beacon signals allow wireless clients to maintain contact with
the wireless bridge. They may also carry power-management information.
(Range: 20-1000 TUs; Default: 100 TUs)
Data Beacon Rate – The rate at which stations in sleep mode must wake up to
receive broadcast/multicast transmissions.
Known also as the Delivery Traffic Indication Map (DTIM) interval, it indicates how
often the MAC layer forwards broadcast/multicast traffic, which is necessary to wake
up stations that are using Power Save mode. The default value of 2 indicates that
the wireless bridge will save all broadcast/multicast frames for the Basic Service Set
