If you’ve been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire 802.11 specification, then look no further. This comprehensive overview describes the underlying principles, implementation details, and key enhancing features of 802.11n and 802.11ac. For many of these features, the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of the key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40\80\160 MHz channels, transmit beamforming, and packet aggregation) is given, in addition to clear summaries of the issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughout, including revised chapters on MAC and interoperability, as well as new chapters on 802.11ac PHY, and multi-user MIMO, making it an ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communication.
