Systems and methods comprise determining a received signal strength (RSSI) of a signal. A sensitivity level of a receiver is determined, where the signal is to be received at the receiver. When a determination is made that the RSSI is greater than the sensitivity level, a transmitter power level is calculated as a difference between the RSSI and the sensitivity level. A transmitter of the signal is controlled in accordance with the transmitter power level.
