Abstract
Systems and methods are provided for reducing multi-modulation radio transmit range. The method comprises determining a data modulation type at which a transmitter is operating, and adjusting a transmitter power according to the data modulation type to control transmit range. Each data modulation type may be determined to operate at a designated transmit power level by determining each data modulation type and arranging in order of a data connection rate corresponding to each data modulation type. For each data modulation type, the difference between a minimum signal-to-noise ratio (SNR) at the connection rate and a minimum SNR at the next higher connection rate is calculated. Starting with the lowest data connection rate and at the maximum transmit power, the transmitter power levels are calculated for each data connection rate such that the transmitter range is limited and operation at the highest data connection rate is permitted.
