Various arrangements for managing wireless network communication are described. Two cells using different radio access technologies (RATs), such as a 3G cell and a 4G cell, may provide overlapping coverage. A first cell using a first RAT, under certain circumstances, may be permitted to enter a powered down state such that less power is consumed. User equipment may communicate with the cell using the second RAT as the preferred network and only communicate with the cell using the first RAT when a service available through the first RAT but not the second RAT has been requested. Upon a request from the second cell, the first cell may enter a powered up state.
