    Abstract: Techniques for operating cellular internet of things (IoT) devices under a public cellular carrier are disclosed. During an active connection, the cellular IoT device's radio-controlling application can collect radio metrics by tapping into the diagnostics interface of IoT device's cellular modem to collect data regarding accumulative signal strength, block/bit error rate, and/or round-trip latency for the session, etc. During the active connection, battery and environmental information as well as application-based information can be collected and sent to a remote computing device. In an example, the cellular IoT device can be given revised or refined values for use in timers, which may be used by the device to more efficiently use idle and/or power-save modes to reduce battery power consumption. Moreover, the use of the timers may be extended to devices distinct from the cellular modem, thereby increasing the utility of the timers and the functionality of the IoT device.

    Abstract: One embodiment of the present invention sets forth a technique for operating an electronic device. The technique includes an electronic device determining one or more signal characteristics of a link between the electronic device and a base station, estimating a coupling loss for the link based on the one or more signal characteristics, determining whether the coupling loss exceeds a maximum coupling loss (MCL) for the link; and in response to determining that the coupling loss exceeds the MCL, delaying transmission of one or more messages from the electronic device over the link to the base station.

    Abstract: One embodiment of the present invention sets forth a technique for operating an electronic device within a cellular environment. The technique includes determining one or more radio frequency (RF) link parameters associated with a link between the electronic device and a cellular base station at a first point in time. The technique also includes computing a first estimate for a pseudo-coupling loss (PCL) for the link based on the one or more RF link parameters. The technique further includes determining that the PCL exceeds a maximum coupling loss (MCL) for the link based on the first estimate and delaying transmission of one or more messages from the electronic device over the link until a second point in time that is later than the first point in time.

    Abstract: A cellular modem is configured for low power applications. In some instances, the cellular modem includes a transceiver, a processor to control the transceiver, a memory device in communication with the processor, and a general-purpose input/output (GPIO) pin, controlled by the processor. In an example, the cellular modem receives an appointed time for an upcoming communication and determines a time to activate a power supply. The determination may be based at least in part on the appointed time for the communication, so that the power supply is ready to supply power at a level consistent with use of the transceiver at the appointed time of the communication. At the determined time, a signal from the GPIO pin is used to activate the power supply, resulting in an increase in power supplied to the cellular modem in a just-in-time manner.
