Thermal mitigation details (device response to different temperatures)
The GO9+ offers much more cellular data access as compared to the GO9 device. As such, it includes a much more powerful
CAT4 cellular modem that is capable of providing quick network speeds for Telematics and Wi-Fi data. Since the internal
temperature of the device can affect device performance, the mitigation logic below is used to protect against any overheating
scenarios.
