Transmit Power
Normally the wireless transmitter operates at 100% power. In some circumstances, however, there might be a
need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can prevent
transmissions from reaching beyond your corporate/home office or designated wireless area.
RTS Threshold
When an excessive number of wireless packet collisions are occurring, wireless performance can be
improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless
transmitter will begin to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the
RTS Threshold. This setting should remain at its default value of 2346 bytes.
Fragmentation Threshold
Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF
interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater
than the Fragmentation Threshold. Setting the Fragmentation value too low may result in poor performance.
WMM Enable
Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless
connection.
Short GI
Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some
installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for
your installation.
