Mobile communication has become an everyday commodity. In the last decades, it has
evolved from being an expensive technology for a few selected individuals to today’s
ubiquitous systems used by a majority of the world’s population.
The world has witnessed four generations of mobile-communication systems, each
associated with a specific set of technologies and a specific set of supported use cases.
The generations and the steps taken between them are used here as background to
introduce the content of this book. The rest of the book focuses on the latest generations that
are deployed and under consideration, which are fourth generation (4G) and fifth generation
(5G).
