It’s been a while since we last talked about Spectrum Analysis (SpecAn). It was all the way back on Episode 39. In this episode, we’re going to define what Spectrum Analysis is. We’ll then discuss why we should perform SpecAn. Maybe it’s because you want to locate a source of interference. What are the different […] The post CTS 264: Spectrum Analysis appeared first on Clear To Send.

Mathy Vanhoef, a well respected Wi-Fi security researcher, has identified a dozen vulnerabilities in the 802.11 protocol called FragAttacks. FragAttacks is short for Fragmentation and Aggregation Attacks. It’s based upon how wireless frames are received and reassembled on a device or access point (AP). Unfortunately, this vulnerability has been present since Wi-Fi existed  and nearly […] The post CTS 263: Wi-Fi Vulnerability – FragAttacks appeared first on Clear To Send.

Are we relying too much on proprietary tech to optimize Wi-Fi for client devices? Recently, Rowell had to optimize a wireless network which became this episode. What do we think about features like client load balancing? Can it work efficiently and how do client devices react to it? Is there a better way to load […] The post CTS 259: Optimizing for Client Devices appeared first on Clear To Send.

New IEEE-802.11 Standard The IEEE published, on February 26th, a new version of the IEEE 802.11 standards. It is called IEEE-802.11-2020. Did you get your copy yet? But take note: 802.11ax didn’t make it to this version – womp womp. You can buy it here if you cannot wait: https://standards.ieee.org/standard/802_11-2020.html Here is the timeline of […] The post CTS 258: This Week In Wireless – 802.11-2020 appeared first on Clear To Send.

In this episode, Rowell and I talk about some of the reasons why we do some AP-on-a-Stick site surveys. Both of us share some of the APoS work we have been doing in different environments. We get into some of the equipment we used to make our measurements. And we also talk about what we […] The post CTS 257: When Should You Do APoS? appeared first on Clear To Send.

This week, we have Troy Martin on the show to talk about IoT. We talk about the IoT landscape and which wireless technologies are used both at home and in the enterprise space.
