The network performance of multi-rate FDD-mode UMTS

The performance of a multi-rate mobile cellular network using the Frequency Division Duplex (FDD) mode of the Code Division Multiple Access (CDMA) based Universal Mobile Telecommunication System (UMTS) is investigated. The new call blocking and call dropping probabilities and the tolerable network load are studied in the context of a multi-rate FDD-mode UMTS network incorporating dynamic threshold assisted soft handovers and shadow fading.
