The traditionally separate Fixed, Mobile, and Internet sectors are now converging into a single sector with implications for both technology and business. With so much happening, and so many options available, it is increasingly essential for telecommunication professionals to have a clear view of where the industry is heading. This book provides a solid foundation on which to develop a modern view of telecommunications. It explores the core requirements of telecommunications, from markets to technology, primarily from the mobile standpoint. It examines how mobile communications is evolving to meet the changing needs of the customer, and how technology is changing to meet those needs.
