QuadRF Augmented Reality View

RF Augmented Reality

Using four coherent antennas, QuadRF measures differences in signal arrival time to render a live RF overlay directly on your phone or laptop at 30fps. Everyday objects—like Wi-Fi devices, wireless cameras, drones, beacons, and lab transmitters—become visible as radio sources with color-coded frequency.

Tap on an RF source, and you can instantly isolate it and pass the signal on to your SDR programs to decode, or transmit a beamformed signal right back. Route signals to video decoders, two-way communication modems, GNU Radio flowgraphs, or your own custom applications running directly on the included Raspberry Pi 5.

An RF Tool for the Real World

The QuadRF Mobile

QuadRF opens up new ways to interact with the wireless world all around you.

Visualize Radiation

Pinpoint the exact physical location of transmitters, hidden wireless cameras, or rogue access points through walls.

Communicate Long Range

Use beamforming to increase signal gain and reject interference for reliable two-way communication, even when moving. Perfect for drone video streams.

Empower Robotics

Give machines a brand-new sensing modality with real-time spatial awareness of beacons and local RF infrastructure around it.

Develop Mesh Networks

Build high-bandwidth wireless relays. With MIMO, transmit & receive from multiple nodes on the same frequency, at the same time.

Test Antennas

Instantly compare how polarization or physical placement changes the RF field to intuitively debug your devices.

Enhance Education

A practical, hands-on teaching tool for university students learning about MIMO, phased arrays, and spatial wireless measurements.

A Complete 4x4 MIMO SDR Kit

Getting started takes seconds. We provide a microSD card preloaded with all drivers, libraries, and example applications—accessible directly from the web browser and released 100% open-source under GPLv2.

Start With Four Antennas. Scale To the Moon.

A single QuadRF is a complete phased-array platform, but it is also designed to grow. We engineered QuadRF from the ground up to serve as the foundational building block for much larger phased arrays. Simply remove the RF board from your QuadRF case and mount it into our open-source interconnect structures.

Mini:   Starter Phased Array

Mini Array
52 cm

The Mini is composed of 18 QuadRF tiles (72 antenna) + interconnect structure


A compact, budget-friendly phased array that already delivers substantial directivity. It’s designed for experimentation and hands-on phased-array learning. Add extension boards later to grow the array further.


Applications

  • Cooperative hobby FPV/video-link experiments, robotics communications research, and educational link-alignment demonstrations, subject to applicable radio rules.
  • High-gain and directional links; repeater backhaul
  • Communications with low-Earth orbit amateur satellites

Performance & notes

  • Array size: 18 tiles (72 antennas) • Beam steering ≈ 60°
  • Expected array gain: ~28.6 dBi • EIRP: ~50.2 dBW (100 kW)
  • Low-latency beamforming; coherent clocking across QuadRF tiles

Power supply: 12 V DC (≈450 W peak)
License: 🪪 Amateur Radio (Technician+) to operate, country restrictions apply.

Moon: A High-Aperture Phased Array

Moon Array
100 cm

Composed of 60 QuadRF tiles (240 antennas) + interconnect structure


A high-aperture array built for Earth-Moon-Earth (EME) experiments and radio astronomy. Delivers the beam-forming gain and EIRP needed for moon-bounce.


Applications

  • EME (Moon-bounce)—transmit and hear your echo or talk with others
  • Milky Way C-band imaging; RF sky surveys
  • Atmospheric and ionospheric sensing experiments
  • Advanced phased array research

Performance & notes

  • Array size: 60 tiles (240 antennas) • Beam steering ≈ 60°
  • Expected array gain: ~33.8 dBi • EIRP: ~60.6 dBW (1.15 MW)
  • Coherent distribution network

Power Supply: 12 V DC (≈1.5 kW peak)
License: 🪪 Amateur Radio (Technician+) to operate. 1 per person. Country restrictions apply.


* Not intended for radar applications. Core functionality needed for radar not included due to export control restrictions.

The complete open-source interconnect structures for the Mini and Moon arrays will be released around the end of the QuadRF campaign. In the meantime, researchers and developers can get a head start with bulk RF tiles available for order via the QuadRF Six-Pack.

A New Frontier for Ham Radio

Bouncing signals off the Moon—known as Earth-Moon-Earth (EME) communication—has long been the ultimate challenge for radio amateurs. It required large antennas, expensive equipment, and accurate manual pointing and tracking. We bring this down to Earth, providing all the tools needed to experience the thrill of space communication, with a software-defined phased array.
