Working on some labs to figure out the combination of driver version and AP config that causes the client to DoS a channel with some weird unmodulated screaming/jamming. Look at that sexy RTFM @ekahau Blog will follow in a few days when I figured it all out

The @ekahau Sidekick proves the old adage that by adding additional people to the task you can truly speed up the process. Did a test with 7 teams surveying at the same time, each using a Sidekick and watching the results aggregate through the cloud was an amazing thing

Amazing read about 802.11ax / WiFi6 providing excellent graphical representations of ax benefits over ac, backwards compatibility, physics behind OFDMA, BSS Colouring, better support for low powered devices, etc. Suprisingly marketing wank free :) cisco.com/c/dam/en/us/produc…

What a great webinar by @DevinAkin about 802.11ax Deployment Best Practices! Would have never thought of a vendor letting you tell so many facts and truths about all the "IFs" of this new PHY. This one got me thinking: "Data Rates may change multiple times per second per client".
