Intelligent control of cellular network coverage using semi-smart antennas for load balancing

This paper examines the issues of traffic load balancing in Wideband Code Division Multiple Access (WCDMA) mobile communication networks through applying dynamic radio coverage. Dynamic radio coverage is achieved by adjusting radiation patterns of antenna arrays and the optimization of coverage is carried out cooperatively between cells using dedicatedly designed algorithm. In comparison with previous work, the discussion starts at how to apply the method to richer models, where propagation effect due to terrain is present. A mapping process is therefore introduced to build traffic pattern using path loss information instead of using geographic locations. The paper then goes on to examine the mechanisms involved in the shaping of radiation patterns for a linear array. Finally, simulation results are used to examine the system level performance of a network employing cooperative coverage¹.
