Abstract
Technologies are described for reliably constraining a maximum transmission power of a mobile communication device such as a cellular phone so that RF radiation associated with that transmission and incident to a head of the device's user can be held at or below predetermined 'safe' levels. Upon determining an operational or communication mode of the mobile communication device where it is likely to be held against or very near the user's head, its maximum transmit power may be reduced until the near-head operation is completed. The reduction may be to a fixed maximum level or may be adjusted to allow for a maximum amount of radiated energy over a period of time. The reduction may also take into account adjustment factors such as frequency band, modulation, antenna gain, and similar factors.
