Mobile communications users are demanding increased reliability, functionality, and accessibility; they want "always on" access to voice, e-mail, text, and multimedia services as they roam from home to auto to office to outdoor/indoor locations. In addition, there is an increasing deamnd to replace separate landline/mobile telephones with a single handset that can be used wherever its owner might be. Answering those customer needs, fixed/mobile convergence (FMC) marries the mobility provided by cellular networks with the extended connectivity provided by 802.11-based WiFi services and...

Following on from the successful first edition (March 2012), this book gives a clear explanation of what LTE does and how it works. The content is expressed at a systems level, offering readers the opportunity to grasp the key factors that make LTE the hot topic amongst vendors and operators across the globe. The book assumes no more than a basic knowledge of mobile telecommunication systems, and the reader is not expected to have any previous knowledge of the complex mathematical operations that underpin LTE.

This second edition introduces new material for the current state of the...
