Welcome to Ruby
Ruby is a complete solution (hardware and software) for robust end to end digital radio links, designed specifically for controlling and managing UAVs/drones/planes/cars and other remote vehicles. Highlights:
- Rendundant radio links: Multiple renduntant radio links in different bands (433Mhz, 868/915Mhz, 2.3, 2.4, 2.5 and 5.8Ghz) can be used simultaneously between vehicles, ground control stations and relays for better resilience, link quality and range;
- Relaying: Mobile (vehicles) and/or fixed relay nodes can be inserted in the system for longer range and penetration beyond line of sight;
- Encryption: The radio links can be encrypted end to end;
- Live video, telemetry, remote control, auxiliary & custom data transport;
- Rich user interface;
- SDKs for third party development of new features.

![]() Here you will find all the info you need and step by step guides on how to build a complete digital radio link to be used for remote controlling vehicles (planes, drones, cars, UAVs), for sending/receiving data, telemetry and for live HD video. The system is built using hardware components available on the market. All you need is the software from the downloads section and the minimal set of components listed in the hardware section. |
Basic system overview:
The system has two main components: ![]() The vehicle, which is responsible with communicating with the controller, getting the video stream from the camera and sending commands to the flight controller and getting the telemetry from it. |
Features highlights: Being a digital link, end to end, gives you advantages over regular analog RF links, like: noise free video feed, ability to send data too (like telemetry and other custom data), error correction, data reliability, have more configurable parameters as it relates to the end to end video link, not just frequency and band; but also parameters like resolution, framerate, resilience and so on; and also enables some exotic scenarios like 3D video, camera switching and so on pretty much out of the box. Ruby supports right out of the box:

What range to expect:
- On 2.4Ghz, using 200mW of power: about 2-3 km range (solid full HD video); Range is shorter if you are in a city area with a lot of WiFi traffic;
- On 5.8Ghz, using 400mw of power: about 3.5-4 km range (solid full HD video); People regularly fly to 7-8 Km out on omnidirectional antennas only with solid link (see resources section for examples);
People have done tens of kilometers distance flights using Ruby, maximum reported range so far is 40 km;
