RF POWER CONTROL USING PROXIMITY SENSOR
First Claim
1. A communication device, comprising:
- at least one transceiver;
a sensor that detects proximity of the communication device with respect to a user; and
a controller that selectively changes at least one operating parameter of the transceiver when the sensor detects that the communication device is proximate to the user.

Abstract
A communication device (100) that includes a transceiver (210), a sensor (230) that detects proximity of the communication device with respect to a user (105), and a controller (205) that selectively changes at least one operating parameter of the transceiver when the sensor detects that the communication device is proximate to the user. The operating parameter that is changed can includes a transmit power of communication signals generated by the transceiver and/or a data transmission rate of signals generated by the transceiver. The communication device also can include a first antenna (215) and a second antenna (220), and the operating parameter that is changed can include a selection of the first antenna or the second antenna through which to transmit an RF signal. The sensor can sense a value of electric field intensity, a value of capacitance, or acoustically measure a distance between the communication device and the user.
