Abstract :
In this article an adaptive radio coverage scheme for increasing capacity in mobile communications is described. The optimization problem of finding optimal coverage for a set of cells is examined and a dedicated algorithm for discovering solutions is described. Method on adjusting radiation patterns of antenna arrays is also given, and the system is called semi-smart antenna, in order to distinguish it from other usage of antenna arrays such as smart antenna. The optimization algorithm developed also allows discovering how differentiated classes of services can benefit from adaptive coverage and the research is done through WCDMA network simulations.
