1. A method comprising:
receiving an indication to transmit a first set of signals within a first frequency range using a first standard via a first plurality of antennas of a radio frequency device and a second set of signals within a second frequency range using a second standard via a second plurality of antennas, the first frequency range not overlapping with the second frequency range;
determining a first power by applying a first weight to a first initial power associated with the first plurality of antennas to maintain a total ratio summation of radiation from the first set of signals and the second set of signals;
transmitting the first set of signals within the first frequency range via the first plurality of antennas using the first power with the first weight applied based on exposure conditions of the first set of signals and the second set of signals;
determining a second power by applying a second weight to a second initial power associated with the second plurality of antennas to maintain the total ratio summation of radiation from the first set of signals and the second set of signals; and
transmitting the second set of signals within the second frequency range via the second plurality of antennas using the second power with the second weight applied based on the exposure conditions of the first set of signals and the second set of signals.
