802.11e Quality of Service – Video

This is a portion of some internal training that I delivered at the beginning of the year.  Certainly not my best stuff, but the video was readily available (thanks to my friend Gary) and I thought that it was useful content about 802.11e, which is Quality of Service.

The video is approximately 5 minutes in length and discusses the media contention mechanism under 802.11e РHybrid Coordination Function (HCF).  There are two main parts to HCF (which I discuss in the video):

  1. Enhanced Distributed Channel Access (EDCA)
  2. Hybrid Controlled Channel Acccess (HCCA)
