Use case #2: Correction data through cellular modem

In this scenario:
1. The LARA-R6 cellular modem receives the correction data and the decryption keys over the
cellular network, using an MQTT connection to the cloud-based Thingstream delivery platform
for IoT services.
2. The NINA-W106 multiradio module then reads the correction data through the 4-pin UART
interface and then forwards the data and the decryption keys to the ZED-F9R GNSS module over
the I2C bus.
The active components in this use case are shown in
