Cisco RRM: Clear To Send Hosts Cisco Champion Radio

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!

Introducing Clear To Send

My name is Rowell and I am the author of Packet6, which is a blog about network & wireless engineering. Today, I am introducing a new self-published podcast called Clear To Send.

The podcast will start off as audio only with the blog to support the podcast by providing show notes from each episode. The topics that will be covered are:

  • Technical education
  • News
  • Opinion
  • Reviews
  • Interviews

Length is still up in the air but I am planning to keep it at 30-60 minutes per episode.

Clear To Send (or CTS for short) is for those who would like:

  • To get started in wireless
  • To get news on the wireless industry
  • Hear opinions on wireless
  • To get educated on wireless topics
  • Listen to interviews
  • Get career tips

Just the beginning

The Clear To Send podcast will be funded by me, Rowell, affiliate marketing links, and advertising on the podcast. As of this writing I have not reached out for any advertisers because I am still experimenting with the podcast.

I do not have any previous podcasting experience. My passion and experience will drive the early beginning stages of the podcast but I am open to feedback from the listeners.

If you have any questions or concerns, feel free to email me at

The journey to this stage took a lot of thought. I’ve always been interested in doing a podcast. Instead of just thinking about it I have decided to just do it. I hope to get the support from my industry peers to help share the podcast and to provide feedback on the published episodes.

So here’s the start of a new journey into podcasting. The blog, Packet6, will still be there. Clear To Send will just be an extension of the blog in audio format.

I hope you enjoy the episodes to come.
