Hello all,
I am studying the possibility of developing a unmanned vehicle communication system based in COFDM and LimeSDR seems the best platform to build this development. That i am trying to get is this:
System description:
- One radio systems handling all UAV communications
– Two or three video streams.
– Telemetry (and mission control)
– Manual control - Long range - 25km
- Frequency 2.4Ghz
I made a small study of similar systems in the market. This long range COFDM technology has been military technology some years ago but now there are commercial products using it, for example DJI Phantom
This table shows some commercial and military products transmitting HD video in long range. My conclusion is that since commercial products that reach only 1km to military products reaching 240km all they have the same RF specifications (a sensibility about -99dBm), they simply change the frequencies and gains of the antennas.
My question is
How easy or difficult would be to develop a system like this?
I am starting to research about this project so any information about how to start or which way take to reach this goal is welcomed.
Best regards,
Jose.
