1. A method comprising:
- determining a back-off function defining a sequence of transmission power adjustments for a future time interval based on at least one detected channel condition that quantifies signal quality between an electronic device and a transmitting entity, the sequence of transmission power adjustments being effective to adjust a predicted average transmission energy of the electronic device over the future time interval to satisfy a power condition defining a permissible average energy for the future interval; and
adjusting transmission power of the electronic device according to the back-off function responsive to satisfaction of a proximity condition.

Abstract
An electronic device disclosed herein includes mechanisms for modeling and dynamically controlling transmission power of an electronic device. The electronic device determines a back-off function defining at least one transmission power adjustment that is effective to adjust a predicted average energy emanating from an electronic device over the future time interval to satisfy a power condition. Power of the electronic device is adjusted according to the back-off function responsive to satisfaction of a proximity condition.
