Abstract
A system for operating a wireless communications device in a manner that significantly reduces the power consumption of the device. In accordance with one aspect of the invention, a system is provided for operating a wireless communications device in a low power mode including the step of controlling the operation of circuit components to operate in either a low-power standby mode or an operating mode. The system includes detecting a first condition and, in response to the detection of the first condition, operating a first set of circuit components in a low-power standby mode while operating a second set of circuit components in the operating mode. The system further includes detecting a second condition and, in response to the detection of the second condition, operating substantially all the circuit components in the operating mode. In the preferred embodiment, the system further includes detecting a third condition and, in response to the detection of the third condition, operating a third set of circuit components in a low-power standby mode while operating a fourth set of circuit components in the operating mode.
