Digital mobile communications and the TETRA system
TETRA is a system for mobile wireless communications and this is a highly topical and comprehensive introduction to the design and applications of TETRA systems including practical examples. TETRA is comparable in structure to the world-wide successful GSM system, however, individual features of TET...
