Cellular network capacity planning using the combination algorithm for total optimisation

The combination algorithm for total optimisation (CAT) is proposed to support smooth upgrading of third generation systems and to fulfil the requirements of current cellular networks. The CAT algorithm solves the problem of base-station location in different environments. Until now experiments were based on simple statistical propagation models such as Okumura-Hata. In this paper new results based on the use of a more complex ray-tracing approach combined with inhomogeneous capacity requirements are presented and discussed. Example results are given for various capacity and coverage targets.
