Abstract

The invention provides optimization of communication links by using a control loop with a relatively long time constant and adjusting particular communication links based upon feedback from a virtual communication unit associated with a communication link. A preferred embodiment of the invention optimizes wireless links in a point to multipoint system, such as a cellular communication system, by dividing a service area into segments and adjusting an antenna beam associated with a segment when a mobile unit is operable therein. This preferred embodiment results in convergence upon an optimized communication link over time and is suitable for use even with highly mobile systems. Preferred embodiments of the invention provide control loops for location or segment optimization as well as for individual optimization.
