Abstract: A method and system for adaptively powering down cells within a cluster are disclosed. According to one aspect, a method includes detecting when a load on a first cell falls below a first predetermined threshold, the load being based at least in part on a number of wireless devices in communication with a first radio unit serving the first cell. Upon detecting when a load on the first cell falls below the first predetermined threshold, a transmitter of the first radio unit is powered down over a period of time to allow time for handoff of wireless devices in the first cell to a second radio unit serving an adjacent cell.
