OVER THE AIR MODEM FIRMWARE UPGRADE BASED ON MESH NETWORK

Abstract:

Systems and methods for upgrading the firmware of a wireless communication device (202). A wireless communication device (202) may comprise a first processor (204) and a first memory (206) configured to receive monitored data from one or more sensors (210), and wirelessly communicate the received monitored data. The device may comprise a modem (220) comprising a second processor (224) and a second memory (226) configured to wirelessly send an identifier for the current firmware stored in the second memory (226); when a firmware upgrade is available, receive an upgrade for the firmware stored in the second memory (226); upgrade the firmware stored in the second memory (226), wherein upgrading the firmware comprises temporarily interrupting wireless communication to and from the wireless communication device (202); reestablish wireless communication to and from the wireless communication device (202); and forward any monitored data received by the first processor (204) and the first memory (206) during the temporary interruption.
