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 608 $aElectronic books. 615 0$aTETRA (Standard) 615 0$aMobile communication systems$xStandards. 615 0$aDigital communications$xStandards. 676 $a621.3845 676 $a621.38450218 700 $aDunlop$b John$cProf.$0944244 701 $aGirma$b Demessie$0944245 701 $aIrvine$b James$0944246 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910139033103321 996 $aDigital mobile communications and the TETRA system$92131617 997 $aUNINA LEADER 02207oam 2200601 450 001 9910709635203321 005 20180608081554.0 035 $a(CKB)5470000002471886 035 $a(OCoLC)896811068 035 $a(OCoLC)995470000002471886 035 $a(EXLCZ)995470000002471886 100 $a20141123d1984 ua 0 101 0 $aeng 135 $aurmn||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aNonmarine sedimentary rocks of Tertiary age in the Lake Mead region, southeastern Nevada and northwestern Arizona /$fby Robert G.
