RTS/CTS medium reservation may provide a solution for networks where:

Density of stations and Access Point RLMs is very low.

You witness poor network performance due to excessive frame
collisions at the Radio Link Modules.

However in most networking environments it is very unlikely that you will
need to enable RTS/CTS medium reservation on the Access Point RLM to
prevent collisions. You are advised to read the information about

Optimizing

Wired Connections (page 121)

prior to changing this setting for the Access

Point RLM.

To enable RTS/CTS medium reservation click the

The Interference Robustness can be activated in exceptional cases when
troubleshooting slow performance of your network that could be related to
in-band interference from e.g. microwave ovens. Interference will usually
show a poor Signal to Noise Ratio (SNR) that is based upon a good signal
level and a high noise level. This behavior is often perceived when:

the “trouble” station or Radio Link Module is close to a interference
source, or

an interference source is located in the signal path between the
“trouble” stations and the Access Point RLM.
