System and method for wireless updates for industrial cellular communication devices in hazardous locations

A system for updating an industrial cellular communications device, said system comprising:

• a rechargeable battery and a cellular modem that is connected electronically to said rechargeable battery;
• an external serial Flash component that receives input from said rechargeable battery via a super capacitor;
• a host that communicates bidirectionally and wirelessly with said cellular modem over a packet based wireless communications;
• and
• a microcontroller that communicates bidirectionally with said cellular modem and said external serial Flash component, and wherein said microcontroller is connected electronically with said cellular modem, wherein said microcontroller facilitates monitoring with said cellular modem of a voltage associated with said rechargeable battery and a temperature associated with said cellular modem, wherein said host establishes a data call with said cellular modem, said data call composed of a data transfer between said host and said cellular modem, and wherein when said voltage associated with said rechargeable battery attains a lower voltage limit, said cellular modem stops receiving data and sends a status code to said host and disconnects said data call and data transfer and enters into a sleep mode during which time said rechargeable battery is recharged and wherein said cellular modem reestablishes said data call with said host after said rechargeable battery has been recharged.
