TETRA is comparable in structure to the world-wide successful GSM system, however, individual features of TETRA are different, often more efficient and better designed than in GSM. TETRA is therefore providing an important source for the further development of standards for mobile telecommunications.This volume is timely and one of the first to cover TETRA and related subject areas.Features 606 $aTETRA (Standard) 606 $aMobile communication systems$xStandards 606 $aDigital communications$xStandards 615 0$aTETRA (Standard) 615 0$aMobile communication systems$xStandards. 615 0$aDigital communications$xStandards. 676 $a621.3845/0218 700 $aDunlop$b John$cProf.$01836990 701 $aGirma$b Demessie$01840961 701 $aIrvine$b James$01342012 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911019195103321 996 $aDigital mobile communications and the TETRA system$94420533 997 $aUNINA
