Abstract :
The paper deals with the evaluation of performances of packet reservation multiple access (PRMA) and code division multiple access (CDMA) in a mixed cellular environment, composed by a regular grid of macrocells plus microcells deployed in the most congested areas. The investigation aims at evaluating the impact of the different interference mechanisms on traffic performance and bases on the comparison between two technical solutions proposed in literature. The approach is quite innovative since the analysis is carried out considering realistic spatial traffic statistics, which are characterized, even with a nominally uniform user distribution, by fluctuations resulting in uneven traffic loads on different cells. Different propagation models for macrocells and microcells have been adopted
