Base-station network planning including environmental impact control

The authors present a method for planning a base stationʹs position in a mobile communication system taking into account both the requirement to minimise the environmental impact of the radiated electromagnetic fields and the requirement to assure a suitable quality of service, i.e. C/I ratio, coverage, efficiency, served traffic. The model is based on five functionals and the overall optimisation procedure is carried out by a genetic algorithm. As an example of its application, the proposed method is applied to an imaginary town, subdivided into areas with different constraints for the previously mentioned requirements. Results reported show the behaviour of each functional, as well as the global optimisation of the network.
