I teach Wireless, Security, and related technologies professionally, and all over the world. Any subject can take years, and even decades to master and Wireless is definitely one that can take some time if we are being honest.

Recently a couple of colleagues challenge me to see if Icould teach a few basic lessons about Wireless and WiFi in under 30 minutes. Get ready to have some fun with an extremely accelerated course covering

1. WLANArchitectures

2. 802.11 PHYProtocols

3. 2.4GHz ISM and 5GHz UNII/ISM

4. 802.11 Frame Format

5. CSMA/CA DCF

6. Stations talking in a cell

While Iknow this 30 minute lesson won't make you a CCIEWireless, CWNE, or ACMX, it won't make you a CCNPWireless, CWSP, CWDP, or CWAP, and honestly wont make you a CCNAWireless or CWNA, but it just might inspire enough of you to start learning more about wireless and if I can get just a few of you interested with a short crazy video, well I think it was worth the challenge.
