This book was written using a tutorial approach and is intended to appeal to a broad audience. The book covers the fundamentals of short-range wireless networking using ZigBee™ and IEEE 802.15.4™ standards. The ZigBee and IEEE 802.15.4 standards are covered with the same level of detail. In addition to technical details, the book contains high-level overviews that would be informative for a reader who is only interested in understanding the general concept of ZigBee wireless networking. This book provides the big picture of ZigBee wireless networking, from the radio frequency (RF) and physical layer considerations up to the application layer details. Considering the multidisciplinary nature of this book, the required background materials are also provided.

A wireless communication network can be viewed as a collection of nodes, located in some domain, which can in turn be transmitters or receivers (depending on the network considered, nodes may be mobile users, base stations in a cellular network, access points of a WiFi mesh etc.). At a given time, several nodes transmit simultaneously, each toward its own receiver. Each transmitter–receiver pair requires its own wireless link. The signal received from the link transmitter may be jammed by the signals received from the other transmitters. Even in the simplest model where the signal power radiated from a point decays in an isotropic way with Euclidean distance, the geometry of the locations of the nodes plays a key role since it determines the signal to interference and noise ratio (SINR) at each receiver and hence the possibility of establishing simultaneously this collection of links at a given bit rate. The interference seen by a receiver is the sum of the signal powers received from all transmitters, except its own transmitter.

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.
