Wireless area network enabled mobile device accessory
First Claim
1. A first device capable of mobile operation, said first device being operable to communicate information, wirelessly, directly to a wide area network (WAN) or indirectly, via a wireless connection to a second device capable of mobile operation and connected wirelessly to said WAN,said first device being further operable to determine whether a low-power short range wireless link can be established to the second device and selectively power-down duplicate functionality including WAN communication functionality and at least one additional functionality on said first device likewise found on said second device in response to the low-power short range wireless link being established between said first and second devices,wherein the first device uses one or more resources of the second device to provide the powered-down duplicate functionality on the first device via the established low-power short range wireless link between the first and second devices, andwherein the first device activates the WAN communication functionality to communicate with the WAN in response to determining that the low-power short range wireless link between the first and second devices cannot be established.

Abstract
A wearable wireless portable device (“WWPD”) includes cellular/WAN communications circuitry for establishing a direct connection to a telecommunication network and a low-power short range radio for establishing an indirect connection to the telecommunication network via the communications circuitry of the more feature-rich mobile device. The WWPD may be configured to deactivate its cellular/WAN communications circuitry (and other resource such as GPS) to communicate with a more feature-rich mobile device (e.g., a smartphone) via low-power short range communication technologies when it is in close proximity to the mobile device, and activate its cellular/WAN circuitry to provide cellular and/or network connectivity when it is not in close proximity to the mobile device. The WWPD does not require the bulky battery systems, which enables the WWPD to be packaged into a small and lightweight device, such as a wrist watch or pendant and enables longer battery life for the battery of the WWPD.
