It describes the basics of how they operate, the different types of wireless voice, data and information services, key commercial systems, and typical revenues/costs of these services. While new competition has provided lower cost services for consumers, it means a rapidly changing marketplace for the wireless industry.

The types of services that mobile telephone systems can offer vary depending on the technologies, devices, and the services selected by customers. This book discusses the different types of systems including 1st, 2nd, 2.5, and third generation wireless (3G).
