A.}, abstract = {The IMT-2000 standard UMTS of (Universal Mobile Telecommunications System) is based on Wideband CDMA (Code Division Multiple Access). To access a shared transmission channel for multiple users, UMTS exploit Code Division Multiple Access (CDMA). Multi-user interference is a critical issue in CDMA, limited user, cell Capacity and limiting spectral efficiency dramatically. The manner of used multiple carriers can provide capacity increases over and above a simple doubling of capacity. Models involving power, signaling and cell size design will be developed to determine the best configuration for improved capacity within the UMTS/3G network. This paper will explain the analytical calculation of Multi-Frequency scenario within UMTS/3G for user capacity enhancement with number of services in cells of clusters. {\^A}{\copyright} 2011 Global IT Research Inst.}, keywords = {3G Networks; Analytical calculation; Capacity increase; Cell capacity; Cell size; Cellular communication; Critical issues; IMT-2000; In-cell; Mobile Communication; Multi frequency; Multi-user interference; Multiple carriers; Multiple user; Number of services; Spectral efficiencies; System capacity enhancement and Wideband communication network; Transmission channels; Universal mobile telecommunications systems; User capacity; Wide-band CDMA, Communication; Innovation; Mobile telecommunication systems; Spectrum analyzers; Telecommunication networks; Wireless networks, Code division multiple access}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-79955684743&partnerID=40&md5=f52a33cb8e607199f23428fabb34e264} }
