Abstract
Tracking devices having extended service life for use as finders, locators, sensors, and radio contact reporters. The devices combine a Bluetooth digital radioset and a cellular frequency modulation radioset and are operative with or without a smart device and with or without a cellular radio network. Finding, locating and sensing are provided as a Bluetooth network service, as a cellular network service, or as a service mediated on a network that combines Bluetooth and cellular radio nodes, with “Bluecell” devices acting as hubs. Bluecell devices can be authenticated on both Bluetooth and cellular networks. Systems and methods for using the dual radio devices are also disclosed. Power management schema made possible by dual radio control of on-board processing circuit function enable extended operation of Bluecell devices as part of an IoT. Remotely controllable devices having a service life of a year or more are described.
