Hi everyone,
I'm new to long range digital wireless communication, and would like to set up a wireless serial link (i.e. wireless UART) between 2 Raspberry Pis. The throughput should be at least 9.6 kbps, and range with line of sight ca. 2 - 3 km. Power consumption and cost are of no importance in this application.
To make interfacing with the RPis easy, I'd prefer a module with USB interface (i.e. a CH340 style integrated USB to UART adapter on both ends). Which modules would be recommendable?
Thanks in advance for sharing your thoughts!
