Abstract
Systems and methods are provided for controlling output energy levels in wireless communications devices, such as wireless USB modems, while optimizing performance of the wireless communications devices. Controlling output energy levels includes controlling specific absorption rate (SAR) levels and heat levels generated by one or more radiating elements in a wireless communications device. Controlling output energy levels is achieved by integrating one or more radiating elements in a movable device, such a fan and/or by incorporating a moving reflector element, such as a fan, proximate to one or more radiating elements. Integrating the one or more radiating elements in, e.g., a fan, or by using a fan near the one or more radiating elements, the radiation pattern resulting from the output energy may be spatially averaged and/or dithered, reducing SAR levels and allowing for excessive output heat energy to be vented and/or one or more radiating elements to be cooled.
