We published our previous book, Essentials of Modern Spectrum Management, in 2007. Much in the world has changed since then, with the explosion in demand for mobile data, the emergence of dynamic spectrum access and other sharing approaches, and the deployment of new auction techniques. Some of the developments that were promising in 2007, such as ultra-wideband, have not yet delivered, while others, such as television white spaces, are now being pioneered.

When we decided it was time for a new edition, we concluded that the changes required to the 2007 version were so extensive as to merit a completely new approach. Hence this book, which aims to cover the major issues relating to the technologies, economics and practices of using and managing spectrum, to consider different approaches, to look ahead, and to make recommendations for future spectrum management.
