I am designing a fixed-wing drone. I am planning on transmitting HD video and some telemetry over a distance of maximum 3 kilometers. I will need a longer-ranged module in the future but it is the future me's problem.
I have checked out some lo-ra modules such as E32 SX1278 but they have extremely low bandwidth. I think that HD video streaming requires around 5mbps and telemetry takes basically nothing so 5mbps should be enough for me.
There are FPV transmitters that are doing basically what I need. However, since they are designed to be used by a standard hobbyist with a rc hardware setup, I really can't use it to transmit telemetry and other types of data, or can I. I honestly don't know.
Of course, the ideal module that I would put on board the drone would be small and cheap but I accept that everything good comes with a price. I have some budget but not very much so I would really like some cost-effective alternatives in addition to some expensive performance modules.
I actually think that we can manage to find a light module since I will be transmitting to and receiving from a ground station. So I can use a transceiver with a huge antenna in my ground station.
To sum up, can you guys recommend some long-range high-speed radio transceiver solutions that fits my requirements. Thank you!
