  • Leveraging location based services for power conservation in multi-mode wireless communication devices
    Patent number: 8103291
    Abstract: A power saving and security enabling method, system, computer program product, and program storage device are disclosed. Wireless communication technology transceivers in a multi-mode wireless communication device are activated and deactivated based on a location detected by a location-based service system. A set of wireless network connection profiles control activation and deactivation of the wireless communication technology transceivers. Reduction in power consumption and improvement in security is achieved by only activating wireless communication technology transceivers when need and deactivating any other transceivers which are not currently connected to a wireless communication network.
