Microcell Overlay for IMT-2000 Cellular System

Cellular mobile service providers would like to service the users in a cost-effective way. The resource demand may depends on the concentration of users in the given area. The Changing of the number of users can also occur over a period of time. This paper proposes about microcells that overlay over a macrocell to increase user capacity of IMT-2000 cellular mobile system. The model uses 7 macrocells cluster and allocates cell size, number of microcell, installation pattern and position of microcell. The result shows that the increasing of the number of microcells is effected by number of user in the microcell. The design of microcell overlay is proposed to find the optimum solution on demand.
