Abstract

We investigate a smart antenna based load balancing scheme, which dynamically changes cell size and shapes according to the geographic call traffic distribution over time. The performance of the whole cellular network can be improved by contracting the antenna pattern around the source of peak traffic and expanding adjacent cells coverage to fill in the coverage loss. Our previous work based on scenarios with nonuniformly distributed traffic scenarios has shown the improvement of system capacity of such a dynamical cellular coverage planning scheme exceeds 20%. A negotiation approach for the real-time control of cellular network coverage is described.
