For battery powered IoT devices when the battery is exhausted the remote systems are not able
to communicate with the device. Store and forward can be used by the server to store the
pending commands for an IoT device and once it is attached to the network and connected to the
server, then deliver the pending commands. However, for time sensitive or security related
commands the time between when the IoT device is powered, connected to the server, and
commands delivered creates additional risks for the IoT device. This caching solution allows for
commands to be cached coming into the IoT radio even when the system itself is no longer
powered. In addition, certain status coming out of the system can be cached at the modem
during times when the system itself may no longer have any battery power, but the radio is able
to now able to re-connect to the network and provide some updated host status.
