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.FeaturesTETRA (Standard)Mobile communication systemsStandardsDigital communicationsStandardsElectronic books.TETRA (Standard)Mobile communication systemsStandards.Digital communicationsStandards.621.3845621.38450218Dunlop JohnProf.944244Girma Demessie944245Irvine James944246MiAaPQMiAaPQMiAaPQBOOK9910139033103321Digital mobile communications and the TETRA system2131617UNINA01841nas 2200577-a 450 991014088930332120241221111014.0(CKB)963018285171(CONSER)---94646367-(MiFhGG)0BSZ(EXLCZ)9996301828517119940520a19949999 --- aengtxtrdacontentcrdamediacrrdacarrierAviation historyLeesburg, VA Cowles History Group©1994-1 online resourceTitle from cover.Published 2006- : Leesburg, Va. : Weider History Group.Print version: Aviation history.
