1. A communication device, comprising:
- a transmitter configured to transmit signals, wherein the transmitter transmits the signals at a first power level;
an input comprising one or more touch sensors; and
a control unit in communication with the one or more touch sensors and the transmitter, the control unit configured to;
detect presence of an object contacting the input; and
increase a power level at which the transmitter transmits the signals in response to detecting the presence of the object.

Abstract
Attenuation of a wireless signal, particularly a short range wireless pairing signal, is accommodated immediately and automatically by a device in response to detection of presence of an object. When a user provides input to the device, such as by touching the device with a finger, presence of the finger may interfere with a signal emitted from the device. To accommodate for such interference, the device may immediately increase its transmission power upon detection of the finger, without waiting for link quality measurements.

11. A method of improving quality of wireless communications for a wireless device, comprising:
-
transmitting, using a transmitter, signals at a first power level; receiving input via one or more touch sensors; and detecting, by a control unit, a presence of an object contacting the one or more touch sensors; and automatically increasing, by the control unit, a power level at which the transmitter transmits the signals in response to detecting the presence of the object. - View Dependent Claims (12, 13, 14, 15, 16, 17)
