The settings 0HGLXP or 6PDOO distance between Access Point
RLMs require a excellent quality of radio communications
throughout the entire wireless coverage area. In environments
where the actual placement of Radio Link Modules was designed to
obtain maximum wireless coverage with a minimum number of
Access Point RLMs, changing the distance between RLMs from
/DUJH to 0HGLXP or 6PDOO will not yield better results. Adversely,
doing so might seriously affect the roaming performance of your
wireless stations, risking network communication errors caused by
“out-of-range” situations.
If you consider using the option 0HGLXP or 6PDOO distance between Radio
Link Modules to create a high performance network, you are advised to read
the section
Frequency Channel Management (page 138) as well.
For more information about Access Point RLM density, please consult
Optimizing Performance (page 116) .

The Multicast Rate identifies the preferred transmission speed for your
Access Point RLM broadcast traffic as forwarded by the Radio Link Module.
Where transmissions at lower data rates are usually more reliable, you may
prefer higher throughput performance over greater coverage for your
wireless radio signal.
For more information about multicast rate refer to the help-file of the
RLM Manager program.
