I am successfully using a 4G LTE network connection to send bidirectional telemetry AND HD (1280X1024 / 25fps) Video from my drones. The video is perfect, the telemetry is perfect - regardless of range (assumes 4G is available). I use my cell phone as a hotspot and connect using MISSION PLANNER on my laptop. The video is "snow free" and is viewed on CHROME or FireFox browsers.
The cost of all the equipment is under $100, but I do have to pay for a data plan ($15-$50/month) - and a small monthly amount for server time. The server setup is special to allow for the 4G<->4G connection. The telemetry data is encrypted, the video data is not (at this time, anyway). The system camera is non-standard but tiny.I can control the drone with a joystick connected through Mission Planner. The latency is 0.8 seconds - max. The total weight of the system is 100 grams. No equipment other than a computer running Mission Planner is needed on the "ground side" (except for a cell phone or other hot-spot).
I was thinking that others could use my setup as well. In that case I would have to set up multiple accounts on the server and manage them. Before I take this any further -
Would anyone else be interested in the setup I have?

interesting. What hardware (i assume a 4G dongle on a companion computer ?) and software is needed on the drone side ?
Charles,
This is very interesting. I was actually looking at some sort of system to have failover to 4G telemetry with video as an option and a gamepad as a backup. Also a RFD 900+ is part of my equipment.
There are a few now that allow you to put an android in you plane and do this. Here is one quite mature option from some clever guy in Egypt.

I would be interested in seeing your setup. You should do a posting. At some point I do want to get this working as I am planning some long range FPV flying over water.
Hi Charles, can I get an account for the server? Mind telling me the model-name of Logitech game controller? I'll try to buy one by local store. Cheers.

The stability of my server is 100%. I'm using Amazon web services.
Mission planner is designed to use a Logitech game controller connected to a USB port. Not the best, but it does work.
Hi Charles, it sounds very interesting. 0.8 second latency, pretty cool. I would like to try the stability of your server? BTW, how you connected the joystick to Mission Planner. Since I don't have joystick, I wonder if my RC transmitter (Turnigy, 8 channels) may replace it.
Good job!

I should add that telemetry only is a lot easier - and cheaper from a data usage standpoint.
I also have a RFD900 on-board. My setup can use either. Currently, the failover isn't totally seamless, but I'm working on that.
So if I'm running close-range, I use the RFD900's, but if the radio goes out of range, I can switch to 4G in about 20 seconds.
