The IEEE 802.11 Handbook describes the technical details of the 802.11 wireless LAN (Wi-Fi) standard. Aimed at an engineering audience, it primarily educates those that are involved in the development of Wi-Fi products. The Handbook also provides useful information to product managers, IT folks, and anyone else that wants to know some details of how Wi-Fi operates, without having to read thousands of pages of dense standards language.
I co-authored the Handbook with Al Petrick. He did the radio related chapters and I did the others. Tim Godfrey wrote the chapter on 802.11e in the second edition. The 802.11e amendment added support for quality of service to the standard.
