It serves as a hands-on, working guide to the way different parts of an integrated 3G mobile network affect quality. The book helps you gain a better understanding of the trade-off between quality of service and the usable capacity of the network, the best applications to use for multimedia applications, and how to handle quality problems.$cPublisher abstract. 410 0$aArtech House mobile communications series. 606 $aGlobal system for mobile communications 606 $aWireless communication systems$xQuality control 608 $aElectronic books. 615 0$aGlobal system for mobile communications. 615 0$aWireless communication systems$xQuality control. 676 $a384.5 700 $aLloyd-Evans$b Robert$0971438 801 0$bCaBNVSL 801 1$bCaBNVSL 801 2$bCaBNVSL 906 $aBOOK 912 $a9910456047903321 996 $aQoS in integrated 3G networks$92208386 997 $aUNINA
