Full Description
This practical resource gives professionals the information needed to analyze and evaluate the performance of satellite links and networks, and to understand the issues and limitations of IP/ATM over SATCOM technology, used for the transmission of multimedia information services. The book examines current and future land mobile satellite (LMS) communication systems, and the techniques necessary to support reliable and efficient communication.
