Rates This indicates the current rate at which the radio is operating, which can
be set as desired by the user.
Auto Rate Fallback Allows radio to fall back to lower data rate.
Dial a Power Dial a Power is used to set the output power of the radio at the N
Connector.
The valid radio power range is from -5 dBm to 23 dBm
Antenna Gain This is the gain of an antenna attached with the airPoint™ unit.
User can select anywhere between 2.2dBi to 30 dBi.
RF cable Loss This refers to the loss of a cable connecting antenna and airPoint™ unit
View Association Table List all associated clients and its link status.
Note: The default value for Dial a Power is 18 dBm for FCC domain.
At high TX power levels, due to Amplifier saturation, radio tends to distort EVM. So we
suggest that you try to use lower than the maximum power level.
2.4.3. Radio Protocol
The user can edit the wireless radio protocol parameters to optimize the radio performance. The radio
protocol parameters are:
1) Fragment Length (between 256 and 2346)
2) RTS/CTS (between 256 and 2346)
3) RSSI Threshold (between -90 and -20)
4) Preamble settings: Long, Short or Dynamic
5) Throughput Optimizer

Fragment Length a) Show current value
b) Change to a value within its range
This setting determines the size at which packets are fragmented (sent as
several pieces instead of as one block).
Default value is 2346 bytes. The range of value is from 256 to 2346 bytes.
RTS/CTS Length a) Show current value
b) Change value
RTS: request to send
CTS: clear to send
The RTS/CTS length determines the packet size at and bigger than which
the radio issues a request to send (RTS) before sending the packet.
Default value is 2346 bytes. The range of value is from 256 to 2346 bytes.
RSSI Threshold The User can set the minimum value of RSSI Threshold. The range is from
-90 to -20.
