François and I were fortunate to be able to host Cisco Champion Radio this week. We tackled the topic of Cisco Radio Resource Management (RRM) with subject matter expert, Jim Florwick.
Jim is a Technical Marketing Engineer with deep knowledge of how Cisco RRM works.
I started off the conversation by asking Jim what the most common misconceptions are of RRM. He provides a great response because many people seem to leave RRM at its defaults or believe RRM would fix all their RF problems.
Jim provides insight into how the algorithms work and how you should consider them into your design or existing WLAN infrastructure. The important tip he provided was to initiate a DCA restart when major changes have been applied to the WLAN. These changes can be new APs, channel changes, a new controller, you name it.
François asked an important question, how do you perform your validation surveys with RRM in mind? Jim responded with freezing RRM to prevent any changes from occurring while you’re conducting your validation survey. You don’t want to see the same AP shown with two different channels or have transmit power changing while you’re doing your survey.
We then go into the addition of FRA and the complexity it adds to RRM and other topics as well. Give the episode a listen on SoundCloud!
