Abstract
Methods and apparatus for active and passive dynamic electromagnetic radiation emission control in wireless devices by limiting transmit power in individual devices is disclosed. In various embodiments, electromagnetic radiation emissions from wireless devices are dynamically controlled using variable transmit power limits acquired through the use of RF ID/NFC tags that indicate transmit power limits, where such power limiting tags are embedded in clothing, furniture, etc., communication of transmit power limits over Bluetooth or other short range technologies, location-based transmit power limits, user input transmit power limits. Controlling the transmit power of mobiles as well as femtocells/access points for the purpose of minimizing SAR using variable transmit power limits is detailed.
