Abstract:
1. A method for regulating power in a wireless communication terminal, the method comprising: repetitively switching power-on and power-off to a RF transmitter circuit and/or a RF receiver circuit; sensing movement by the wireless communication terminal from a previous location; and regulating the power-on to power-off duty cycle of the RF transmitter circuit and/or the RF receiver circuit in response to the sensed movement, wherein: the RF transmitter circuit is configured to encode and transmit a signal according to at least one cellular communication protocol; the RF receiver circuit is configured to receive and decode a signal according to the at least one cellular communication protocol; sensing movement comprises searching for signals from WLAN devices; and regulation of the power-on to power-off duty cycle of the RF transmitter circuit and/or the RF receiver circuit comprises: increasing the power-on to power-off duty cycle in response to newly discovered signals from a WLAN device that is separate from the communication terminal; and decreasing the power-on to power-off duty cycle in response to detecting absence of signals from the previously discovered WLAN device.
