UMTS (Universal Mobile Telecommunication System) ist die dritte Generation von Telekommunikationssystemen und beruht auf der Funkschnittstelle WCDMA (Wideband Code Division Multiple Access). WCDMA bietet im Vergleich zu CDMA Vorteile durch die Nutzung eines breiteren Übertragungsbandes, eine hohe Übertragungsrate (maximal 2 Mbit/s) sowie eine gesteigerte Systemkapazität und Kommunikationsqualität durch statistisches Multiplexing. UMTS macht Dienste für die Benutzer von mobilen Computern und Mobiltelefonen unabhängig von ihrem Standort zugänglich und ermöglicht innovative Dienste (zum Beispiel pay-per-bit, pay-per-session, flat rate, asymmetric bandwidth, Video Conferencing, Virtual Home Environment und andere). Dieser Band führt Sie in zellulare Netze und die digitale Kommunikation ein. Behandelt werden die Funkschnittstelle, der Funkzugang und das Basisnetzwerk. Gut verständlich werden die 99er Spezifikation erklärt sowie UMTS-Dienste und zukünftige Dienste, die über 3G hinausgehen, vorgestellt. Viele Übungsaufgaben, teils mit Lösungen, erleichtern das Vertiefen des Stoffes.
