Controlling transmit power in a wireless device

A wireless device comprising:

• an interface for receiving a wireless signal and transmitting a wireless signal with a desired transmit power determined as a result of detection of a parameter of the received signal;
• a storage module storing at least one desired maximum transmit power;
• and
• a processor connected to the interface and the storage module and erased to execute a computer program which carried out the steps of:
• generating a sequence of attenuation factors by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power;
• using each attenuation factor in turn to a) reduce the measured value of the received signal power;
• and/or b) reduce a determined desired value of the transmit power, whereby the transmit power is continually reduced as the variable is increased.

A computer program product comprising computer instructions recorded on a non-transmissible media or in the form of non-transmissible signals which when loaded into a processor causes the processor to implement a method of controlling transmit power,

• generating a sequence of attenuation factors by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power;
• and
• using each attenuation factor in turn to a) reduce the measured value of the received signal power;
• and b) reduce a determined desired value of the transmit power, whereby the transmit power is continually reduced as the variable is increased.
