See Wireless Signals. Steer Beams. Scale Arrays.
QuadRF is officially live! We’ve built the first affordable, plug-and-play 4x4 MIMO software-defined radio (SDR) kit that functions right out of the box as a real-time RF camera.
Designed for developers, educators, hardware hackers, and amateur radio enthusiasts, QuadRF replaces tens of thousands of dollars of bulky lab equipment with a single $499 device. It completely lowers the barrier to entry for spatial RF, beamforming, and phased-array development.

Using four coherent antennas and an integrated Raspberry Pi 5, QuadRF measures signal arrival times to render a live, color-coded RF overlay on your smartphone or laptop at 30fps. You can physically pinpoint Wi-Fi devices, drones, or wireless cameras in your environment, tap to isolate their signals, and pass them directly to SDR programs to decode or transmit a beamformed signal right back.
What’s in the Kit:
- True 4x4 MIMO: Full-duplex Tx/Rx in the C-Band with 40 MHz instantaneous bandwidth per antenna.
- Ready Out of the Box: Includes the QuadRF tile, four dual-polarization antennas, an active-cooling enclosure, and a built-in Raspberry Pi 5. No host PC required.
- 100% Open-Source Software: Pre-loaded with GPLv2 drivers, a Web GUI, and fully compatible with GNU Radio, SoapySDR, and ZeroMQ.
- Endlessly Scalable: Start with four antennas, or pull the tile from its enclosure and chain them together to build massive arrays (up to 240 antennas!) for radio astronomy, moon-bounce or long-range mesh networks.
