Abstract
Portable user devices are provided that communicate wirelessly with base stations. A user device may include a transceiver, a power amplifier, a voltage supply, and a global positioning system (GPS) unit. The device may transmit signals at a certain transmit power to a neighboring base station. The device may log the time spent transmitting at each power level. Each data point may be tagged with the current location of the device. The logs of each device may be aggregated by a power optimization server. The power optimization server may calculate optimum power settings for each region and for each type of device. A region may be any desirable size ranging from the size of a single cell to an entire continent. Device users may download updated optimum settings. A device may automatically detect and select the optimum transmit power setting during operation depending on its current location.
