Explore a comprehensive review of the motivation for wireless coexistence and the standards and technology used to achieve it.

Wireless Coexistence: Standards, Challenges, and Intelligent Solutions delivers a thorough exploration of wireless ecosystems sharing the spectrum, including the multiple standards and key requirements driving the current state of wireless technology. The book surveys several standards, including IEEE 802.22, 802.15.2, and 802.19.1 and expands upon recent advances in machine learning and artificial intelligence to demonstrate how these technologies might be used to meet or exceed the challenges of wireless coexistence.

The text discusses cognitive radio in the context of spectrum coexistence and provides a comparison and assessment of using artificial intelligence in place of, or in addition to, current techniques. It also considers applications to communication theory, learning algorithms for passive wireless coexistence strategies, spectrum situational awareness, and active wireless coexistence strategies.

Fast forward to today, and the landscape is very different. The widespread availability of Software Defined Radio (SDR) hardware and software development environments have allowed students, early career engineers, practitioners in other disciplines, and maybe more importantly entrepreneurs to implement and deploy wireless capabilities much, much faster than was possible 20 years ago. Furthermore, advanced high‐level tool chains allow us to implement signal processing functionality on Field Programmable Gate Arrays (FPGAs) and Graphical Processing Units (GPUs), with limited experience on either platform; something unheard of even 10 years ago. More recently, GPUs have been targeted for Machine Learning (ML) and other highly parallelizable computing operations. ML is increasingly playing a larger role in wireless communications applications, which we investigate in this text.

This lower threshold to fielding wireless capability has been in direct response to the explosion in demand for wireless services and the perceived lack of spectrum available to support these services. History has shown that regulatory bodies cannot solve this problem with static spectrum allocations; hence our need to devise ways to coexist with one another in the spectrum. This certainly does not suggest or promote a wild-west scenario where spectrum allocations are routinely hijacked, but does suggest that where feasible, multiple users can coexist to maximize spectrum utilization without sacrificing quality of service. This is one of the tenets of Cognitive Radio, which is still a highly active research area today.

With the necessity of spectrum sharing and the scarcity of unused spectrum on the rise, the standardization of wireless coexistence becomes more important with each passing day. Readers will learn about the challenges posed by shrinking wireless real estate and from the inclusion of topics like:

A thorough introduction to the concept of, and motivation for, wireless coexistence, including congestion and interference, policies, and regulations
An exploration of different wireless coexistence standards, including the need for standardization and various protocols, including 802.22, 802.15.2, 802.19.1, P1900, and 3GPP Release 13/14 LAA
A discussion of the applications of communication theory, including primary user strategies, primary multi-user protocols, and successive interference cancellation
A treatment of concepts in learning algorithms

Perfect for scientists, researchers, engineers, developers, educators, and administrators working in the area of wireless networks, Wireless Coexistence: Standards, Challenges, and Intelligent Solutions will also earn a place in the libraries of graduate students studying wireless networks and seeking a one-stop reference for subjects related to wireless coexistence standards.
