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 I could 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. WLAN Architectures

  2. 802.11 PHY Protocols

  3. 2.4GHz ISM and 5GHz UNII/ISM

  4. 802.11 Frame Format


  6. Stations talking in a cell

While I know this 30 minute lesson won't make you a CCIE Wireless, CWNE, or ACMX, it won't make you a CCNP Wireless, CWSP, CWDP, or CWAP, and honestly wont make you a CCNA Wireless 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.

Who this course is for:

  • Anyone in IT
  • IT Technicians
  • Computer Technicians
  • Network Administrators
