Abstract
The signals to interferences ratio (SIR) received by the mobiles and the base stations of a CDMA network have to satisfy some constraints for a mobile to be connected to a base station. We show that the uplink and downlink interference factors, which represent the "weight" of the network on a given cell, characterize the CDMA networks. We develop, and validate, an analytical fluid model of the network, and establish explicit formulas of the interference factors for each link. This analytical model, simpler than the existing ones, can easily be used for different kinds of CDMA networks analysis, without any computation. As an application, we propose an analytical call admission control (CAC) study for the two links, which takes into account the whole network around a given cell, and show that it is sufficient to do the analysis only for one link. We end our analysis with the development and the validation of the fluid model for a more realistic non homogeneous network.
