I was recently asked by another (wired) engineer for a quick read to get up to speed with RF / 802.11. My answer, "Im going to let my Chauffeur answer that...."
As he gave me the look ... I said,"Ill send you the link"
If you haven't read this classic by Joseph Bardwell what are you waiting for ! This is a great PDF read and its easy on the eyes, well kinda. If you are new to RF / 802.11 this could close some of your learning gaps!
