Abstract :
With regard to the requirement of high capacity and high quality speech and data transmission of future communication systems, we study the application of macroscopic diversity in cellular systems. Macrodiversity is applied during the entire call in order to improve coverage and link quality. The influence on system capacity is studied by the means of discrete event simulation. We propose an access network architecture and cellular layouts which can support macrodiversity. For resource management we apply dynamic channel assignment with an appropriate admission control to guarantee a minimum link quality for all users
