  • Patent number: 11310664
    Abstract: In one illustrative example, a mobile network extender has a network interface configured to connect with a host router and a cellular modem configured to provide a wireless link for communications via a cellular mobile network. In a pairing process, the extender may establish a secure encrypted channel with the router via the network interface. In a locking process, the extender may receive information from the router and verify the information. Upon verification, the extender may be set in a locked state in which the extender is logically locked to the router. The extender may also receive and store a secret session key from the router, and permit the router to acquire the extender for communications. In the locked state, the extender may permit or deny subsequent router acquisition upon router reconnection based on verifying, using the secret session key, authentication data received via the network interface.

  • Publication number: 20180288662
    Abstract: In one embodiment, a device, having a first and a second network interface, detects a switchover by the first network interface from using a preferred wireless access standard to access a carrier network to using a second wireless access standard to access the carrier network. The device identifies when the preferred wireless access standard is again available from the carrier network using the second network interface and causes the first network interface to switch to using the preferred wireless access standard, based on identification by the second network interface that the preferred wireless access standard is again available from the carrier network.

  • Patent number: 9986509
    Abstract: In one embodiment, circuitry on a device is configured to detect a power failure of the device, inform a cellular modem of the device of the power failure, and supply capacitive reserve power to the cellular modem in response to the power failure. The cellular modem of the device may then send, using the capacitive reserve power, a cellular detach message into a cellular network, where the detach message has an indication that causes a receiving device to send a notification of the power failure to a configured endpoint device.
