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