UMTS is the third generation mobile networks that enables better network performance than its predecessor in the form of air interface between access network and the core network, quality of service, coverage, capacity, etc. With UMTS, many new multimedia services are introduced. The higher bandwidth of UMTS also enables other new services like video conferencing or IPTV. A packet-switched connection uses the internet protocol, meaning that a virtual connection is always available to any other end point in the network. In third generation networks admission control and congestion control are required to guarantee the quality of service and to maximise the system throughput. The aim of this study was to review analysis of capacity and coverage. Coverage analysis review number of users in UMTS cell with sectorisation and without sectorisation. Capacity analysis shows how many users can be safely supported in the UMTS cell in scenarios with certain traffic mix and mobility characteristics.
