Radio frequency power adaptation for handheld wireless devices

Abstract:

In various examples, radio frequency conducted power of a device--such as a human interface device (HID)--may be adjusted to account for various operating conditions. For example, when a user holds the device in their hand, the radiated power level of the device may be reduced to a level that reduces transmission performance of the device. To account for this, one or more detection mechanisms may be used to determine whether the device is held in hand and, when determined to be held in hand, the radio frequency conducted power of the device may be increased--while complying with regulatory requirements governing wireless transmissions--to increase the performance of the device. When not held in hand, the radio frequency conducted power may be less, thereby resulting in consistent performance of the device under varying operating conditions.
