Summary:A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station is associated with a subset of registered user equipment. An activation server switches the underlay base station between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole.
