Apparatus and method for manipulating transmission power in a wireless communication device
First Claim
Patent Images
1. A method implemented on a wireless device comprising:
- determining strength of a received signal;
determining a type of a message to be embodied in said signal transmission attempt;
selecting a first power level for a signal transmission attempt based on said strength of said received signal and based on said type of message;
determining if the signal transmission attempt is successful; and
increasing said first power level to a second power level if a predetermined number of signal transmission attempts at said first power level are unsuccessful.

Abstract
An apparatus and method are disclosed for improving signal transmission on a wireless device such as a personal digital assistant, wireless messaging device, or cellular phone. An initial transmission power level is selected based on received signal strength. If subsequent transmissions at the initial power level are unreliable, then the power is increased by a predetermined amount. Power level increases continue until signal transmission is reliable or the highest power level is reached. One embodiment of the system maintains its heightened power level across multiple communication dialogs.
