Apparatus and methods for reconfiguration of a communication environment based on loading requirements. Network operations are monitored and analyzed to determine loading balance across the network or a portion thereof. Where warranted, the network is reconfigured to balance the load across multiple network entities. For example, in a cellular-type of network, traffic loads and throughput requirements are analyzed for the access points and their user equipment. Where loading imbalances occur, the cell coverage areas of one or more access points can be reconfigured to alleviate bottlenecks or improve balancing.
