Amazon.com just posted my five star review of 802.11 Wireless Networks: The Definitive Guide, 2nd Ed by Matthew Gast. Gast: “I tend not to read and review books on as broad a subject as “wireless networking” Gast: One of the marks of a great book is authoritatively answering a question I’ve pondered for a while. This is absolutely false.” Gast: Only the protection frames are required to be transmitted at the 80211b-compatible data rates.”]
