This is a telemetry link for drones with full duplex in mind. This link has two separate channels of communication, one up-link and one down-link on separate frequencies in the WiFi spectrum.

The programming is done via terminal, but the firmware is open and based on Arduino code, so anyone can modify it.

The output power is at max 34dBi, but it can go below 22, so for every country, you can customize the max transmit power.

I made it because on the market I couldn't find any alternative with high speed (325,650,1300 kbps) and long range.

For my use, this is a very useful instrument because i can use a telemetry down-link to fly a drone without a camera with relative security. RTK is not a problem, with a high-speed uplink and a dedicated COM port transmitting correction data over 20Hz without affecting the telemetry.
Even the Rc link is transmitted from a PPM input on the ground, and injected as Mavlink or PPM out.

We tested ground-to-ground communication with a 5dBi antenna transmitting, a 12dBi antenna receiving at 650kbps with 30db out power, i achieved a 50km stable link with a surplus budget link of 10 db.
