Abstract: In one embodiment, a diagnostic device determines signal strengths of two antennas of a multi-antenna device. When the signal strength of each of the two antennas is unacceptable, the diagnostic device provides a recommendation to adjust each of the two antennas. Alternatively, when the signal strength of a first antenna of the two antennas is unacceptable while the signal strength of a second antenna of the two antennas is acceptable, the diagnostic device provides a recommendation to adjust the first antenna. However, when the signal strength of each of the two antennas is acceptable, but a difference between the signal strength of a first antenna and a second antenna of the two antennas is greater than a threshold, then the diagnostic device determines a weaker antenna with weaker signal strength between the first antenna and the second antenna, and provides a recommendation to adjust the weaker antenna.

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.

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.
