What is the difference between IEEE 802.11ac and 802.11ad?
Microwave & RF article, April 2013. The goal is for all IEEE 802.11 standards to be backward compatible and for 802.11ac and 802.11ad to be compatible at the medium-access-control (MAC) or data-link layer. They should differ only in physical-layer (PHY) characteristics. Read about how that goal is being attained.
