Wireless communication terminals
First Claim
1. A radio communication terminal comprising a radio module for processing radio signals, a processor for processing digital signals associated with the radio signals, an audio generator adapted to generate an audio input signal to the processor in response to sound in the vicinity of the terminal, a power supply, and a power controller to control connection of the power supply to the radio module and having a standby mode in which the radio module and processor are energised periodically to detect a radio channel, characterised in that the power controller energises the audio generator to generate an audio input to the processor only during the radio channel, and the processor is adapted to respond to a predetermined sound by activating said terminal for communication.

Abstract
The audio input system (6) of a terminal, such as a mobile telephone, is powered up during the standby mode, either with the paging channel or any other short duration channel such as a monitoring channel, and is then used to recognise narrow bandwidth sounds such as a whistle, to activate the telephone. Once activated, the telephone may then be responsive to voice commands and may then support a speaker phone mode of application.
