Method for switching between predefined transmit power classes on a mobile telecommunications device
First Claim
1. A method of controlling power level of the transmit signals from a wireless device that is communicating with more than one other wireless communication apparatus as part of an ad-hoc network, comprising the steps of:
- a. detecting a first value of a usage parameter of a communication between the wireless device and a first one of the more than one other wireless communication apparatus;
b. setting in the wireless device a power level of a transmit signal for transmitting a message from the wireless device to the first one of the more than one other wireless communication apparatus to a first power level corresponding to the first value;
c. detecting a second value of a usage parameter of a communication between the wireless device and a second one of the more than one other wireless communication apparatus;
d. setting in the wireless device a power level of a transmit signal for transmitting a message from the wireless device to the second one of the more than one other wireless communication apparatus to a second power level corresponding to the second value, different from the first power level, while maintaining an active communication connection with the first one of the more than one other wireless communication apparatus at the first power level.

Abstract
In a method of controlling power level of transmit signals from a wireless communication device that is communicating with a plurality of wireless ad-hoc network nodes as part of an ad-hoc network, a value of a usage parameter of a communication between the wireless device and a first wireless ad-hoc network node of the plurality of nodes is detected. A power level of a transmit signal from the wireless device to the first wireless ad-hoc network node is set to a level corresponding to the value of the usage parameter. A device for adjusting a power level in a wireless device includes a parameter detection circuit, that detects a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node, and a power selection circuit that sets a transmit signal power level from the wireless device to a level corresponding to the parameter detected by the parameter detection circuit.

8. A power adjustment module for adjusting a communication power level in a wireless device, comprising:
-
a. a signal detection circuit that detects a signal and identifies a value of a parameter indicative of a relationship between the wireless device and a wireless ad-hoc network node; b. a power selection circuit that causes the wireless device to generate a transmit signal so as to have a first power level when the signal detection circuit indicates that the parameter has a first value and that causes the wireless device to generate the transmit signal so as to have a second power level, higher than the first power level, when the signal detection circuit indicates that the parameter has a second value, different from the first value; c. a first RF path and a second RF paths, each path being associated with a different one of the first power level and the second power level; and d. a set of RF switches coupled to the power selection circuit and the first RF path and the second RF path for selecting the particular one of the first RF path and the second RF path is used for a corresponding timeslot, in order to support different respective power levels associated with the transmit signal for transmitting a message of an active concurrent communication connection with a respective one of more than one different wireless ad-hoc network nodes, wherein the transmit signal to different wireless ad-hoc network nodes is set to different power levels, while maintaining multiple active communication connections with different ones of the wireless ad-hoc network nodes. - View Dependent Claims (9, 10)
