Abstract: In order to improve communication with another electronic device, during an advertising mode an electronic device (such as a smartphone) may transmit a packet with advertising information using a default transmit power level. Then, based on feedback about a performance metric associated with the communication from the other electronic device, the electronic device may selectively increase the transmit power level for a subsequent packet. Because this selective increase in the transmit power level may increase the overall power consumption, the change in the transmit power level also may depend on one or more factors, such as a battery power level of the electronic device. However, the selective increase in the transmit power level may, in some instances, decrease the overall power consumption by reducing or eliminating retries.

Abstract: A device implementing a system for preventing duplicate wireless transactions includes a wireless communication controller that is configured to receive a signal for conducting a wireless transaction with a wireless transaction terminal. The wireless communication controller is further configured to determine whether a transaction type of the wireless transaction is associated with a signal strength threshold. The wireless communication controller is further configured to measure a signal strength associated with the wireless transaction upon determining that the transaction type of the wireless transaction is associated with the signal strength threshold. The wireless communication controller is further configured to prevent the wireless transaction from completing when the transaction type of the wireless transaction is associated with the signal strength threshold and the measured signal strength fails to satisfy the signal strength threshold, otherwise allow the wireless transaction to complete.
