GPRS is based on GSM communications and complements existing services such as circuit switched cellular phone connections and the Short Message Service (SMS).GPRS represents the bridge between 2G and 3G mobile telecommunications and is commonly referred to as 2.5G. Implementation of GPRS requires modification of the existing GSM networks in that GSM is a circuit switched technology while GPRS is packet orien 606 $aGeneral Packet Radio Service 615 0$aGeneral Packet Radio Service. 676 $a621.3845/6 701 $aSanders$b Geoff$f1966-$01759660 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910877343403321 996 $aGPRS networks$94198259 997 $aUNINA
