TETRAis comparable in structure to the world-wide successful GSM system,however, individual features of TETRA are different, often moreefficient and better designed than in GSM. TETRA is thereforeproviding an important source for the further development ofstandards for mobile telecommunications. This volume is timely and one of the first to cover TETRA andrelated subject areas. Features include: * Detailed discussion of public and private mobile communicationsdomain * Architecture, components and services of TETRA and * Design and operational aspects of the system Based on courses for industry, presented by the authors, DigitalMobile Communications and the TETRA System will prove indispensablereading for service providers, design engineers and systemsmanagers in the private mobile communications market.

DOWNLOAD EBOOKTerrestrial Trunked Radio (TETRA) has become the tool to design any type of public security systems, in particular due to the strongly increased security demands for mobile systems. In this book, the authors show how TETRA can be strongly improved and these improvements will most probably be part of future TETRA standards. The areas examined include channel assignment and multiple access techniques, video transmission, wireless LAN integration, and the establishment of multiple wireless mesh networks. Since the requirements for these networks is security, the authors show that innovative techniques such as those based on chaotic signals can be used in order to maximize security. The book is a vital reference point for researchers with ambition to find the general solution for modern problems of public safety.
