Quectel EG95 is a series of LTE category 4 module optimised specially for M2M and IoT applications.
More information: https://www.quectel.com/product/eg95.htm
Quectel EG95 has 4 variants: EG95-E, EG95-NA, EG95-EX, and EG95-NAX.
RAK7244C LoRaWAN gateway supports EG95-E or EG95-NA.

When an end device transmits sensor data, the LoRaWAN gateway does not only transmit this data to the cellular network it also adds meta data to the sensor data.
Besides the sensor data the LoRaWAN gateway also:
- transmits at regular time interval (stat_interval) the gateway status to the LoRaWAN network server (See tutorial 29).
- transmits at regular time interval (keepalive_interval) a keep alive message to the LoRaWAN network server (See tutorial 29).
Both intervals are set in the global_conf.json or local_conf.json file.
In both cases acknowledge messages are send back from the LoRaWAN network server to the LoRaWAN gateway.

The LoRaWAN network server can also send downlink (DL) responses back to LoRaWAN gateway.
The cellular data usage not only depends on the actual sensor data size and response data size but it also depends on the stat_interval, keepalive_interval settings and of course how often sensor data and responses are transmitted.

The RAK7243C and RAK7244C LoRaWAN gateway can not whitelist end nodes.
This means when using the cellular backhaul, you will also pay for cellular data packages from other end nodes not owned by you.
