4G (LTE) Telemetry and Control of Pixhawk using Pi3

I have been developing the solution for 4G / LTE telemetry and control link for Pixhawk using raspberry pi3.

Problems:
- most solutions have high CPU usage / high latency / or use 3G network at most (sakis3g and Wvdial do NOT support 4G)!
- There are almost no solutions for restricted Cell provider (when ports are closed) on both ends (on Raspberry modem and Computer LTE Modem)

Results:
- I have archived latency of 70ms on average and 100ms at most on 3G (4G drops it down to 33ms average)
- VNC / ssh /Mavlink connection over 4g
- Automatic 4G modem recognition and connection (Hot Plug-able!)
- Internet is routed over modem once connected, and routed back to wifi when disconnected Automatically.
- simultaneous operation on local network (wifi) and 4G - thus no reconfiguration is needed if you want to switch over to wifi (simply change the target address and port)
- You can use ANY mobile operator (The only setting that may need to be changed is APN, but it is done by plugging modem into computer-super easy)

This has been developed on special order, no specific details can be disclosed publicly.
