Abstract

Aspects of a method and system for dynamic adjustment of power, antenna direction and frequencies in a femtocell network are provided. In this regard, a communication system may comprise a plurality of femtocells, one or more base stations, and a femtocell management entity that coordinates operation of the plurality of femtocells. One or more parameters may be communicated from one of the plurality of femtocells and/or one or more base stations to the femtocell management entity. The femtocell management entity may be enabled to utilize the one or more parameters to determine configuration information for one of the plurality of femtocells and/or for one or more remaining ones of the plurality of femtocells. One of the plurality of femtocells may be enabled to receive the determined configuration information from the femtocell management entity. One of the plurality of femtocells may be configured utilizing the received determined configuration information.
