Power management scheme for a communication interface of a wireless device
First Claim
1. A system for managing power consumption of a first communication interface of a device, comprising:
- a power activator external to the device to send a power-up trigger signal to the device when an external wireless network needs to communicate with the device via the first communication interface;
a second communication interface inside the device to receive the power-up trigger signal from the power activator;
a power management module coupled to the first and second communication interfaces to cause the first communication interface (1) to power off when the first communication interface is determined to be no longer needed and (2) to power up when the power management module receives the power-up trigger signal from the second communication interface.

Abstract
A system for managing power consumption of a first communication interface of a device that communicates with an external wireless network is described. The system includes a power activator external to the device to send a power-up trigger signal to the device when the external wireless network needs to communicate with the device via the first communication interface. A second communication interface is located inside the device to receive the power-up trigger signal from the power activator. A power management module is located inside the device and is coupled to the first and second communication interfaces to cause the first communication interface (1) to power off when the power management module determines that the first communication interface is no longer needed and (2) to power up when the power management module receives the power-up trigger signal from the second communication interface. A method for managing power consumption of a first communication interface of a device that communicates with an external wireless network is also described.
