Publication number: 20170374615Abstract: A system and method for updating industrial cellular communications devices. A supercapacitor and a cellular modem are connected electronically to one another. A host can communicate bidirectionally and wirelessly with the cellular modem. A microcontroller is connected electronically with the cellular modem, such that the microcontroller facilitates monitoring with the cellular modem of a voltage and temperature associated with the super capacitor. When the voltage of the super capacitor attains a lower voltage limit, the cellular modem stops receiving data from the host and sends a status code to the host and disconnects a data call and data transfer and enters into a sleep mode during which time the super capacitor is recharged. The cellular modem can reestablish the data call with the host after the super capacitor has been recharged.Type: ApplicationFiled: June 23, 2016Publication date: December 28, 2017Inventors: Murali Ravipati, Murali Krishna Bezawada, John Boettger, Jayakar Chippada, Krishna Kishore Mendi
