Connecting pixhawk to 4G lte module for telemetry- not using sik radio

Can it be done?
To connect Pixhawk to a companion computer which provides 4G LTE connectivity and a similar arrangement on the GCS side: for telemetry data transmission and give real-time commands. How to ensure MAVLINK communication in such a setup?

There is a product that is out there with great support and also allows video streaming. the developer is working diligently on improving the product every week. I have really enjoyed the seamless setup!!!
