3. Performance Parameters and Bandwidth Controller This chapter gives instructions for editing the wireless radio protocol parameters to optimize radio
performance and for changing the Bandwidth Controller. These procedures are the same for all the
operational modes.
3.1 Link Performance Parameters and Features
The wireless radio performance parameters can be edited 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. Distance
6. Frame Bursting
7. Concatenation
8. Piggy Back
9. Radio Operating Mode
10. Throughput Optimizer

Fragment Length
a) Shows current value
b) Changes to a value within its range
This setting determines the size at which packets are fragmented. If
the frame that the access point is transmitting is larger than the
threshold, it will trigger the fragmentation function.
The use of fragmentation can increase the reliability of frame
transmissions. Because smaller frames are being sent, collisions are
much less likely to occur.
