PROBLEM TO BE SOLVED: To provide techniques for managing communications in a cellular network.SOLUTION: The cellular network can include one or more sectors in which hotspot carriers are deployed. The hotspot carriers can be available to mobile devices beyond sector boundaries defined by the signal strength of ubiquitous carriers. A mobile device can measure a signal strength of a candidate hotspot carrier and estimate a reverse link mobile device transmit power level for communicating on the hotspot carrier. The mobile device determines whether to add, remove, or maintain the hotspot carrier in its active set on the basis of the estimated transmit power so as to limit interference to the reverse link of non-hotspot sectors.
