Native ISAC: one optical signal that carries data and measures distance.
V131 Lab · Native ISAC, on the way to Native ISCC
Native ISAC means sensing and communication are not two systems glued together: one beam, one signal, and one returned stream deliver data and measure distance at the same time. Our indoor laboratory prototype has done exactly that. It is the only publicly verifiable native ISAC to date: the measurements, test conditions, and open questions are published in full.

Native, not glued
The beam that measures is the beam that communicates.
A laser beam is very narrow. A glued system pairs a separate laser rangefinder with a separate laser link, and has to keep two narrow beams, two timings, and two receivers pointed at the same place. In native ISAC, data and distance come from one beam, one received signal, and one timing reference.
The next stage is Native ISCC: Integrated Sensing, Communication, and Control, in which the same stream also feeds control decisions for drones, robots, and vehicles. The Control stage has not yet been validated in hardware.
Work with us
See it live
We demonstrate the laboratory prototype in operation, at our laboratory or live over video: data and distance recovered from the same optical stream as it happens.
Research laboratories
Groups working on optical communication, lidar, or integrated sensing and communication are welcome to a live demonstration and a technical discussion of the published results.
Industry partners
Teams working on drones, robotics, or autonomous vehicles can see sensing and communication from one optical signal in operation and discuss a commercial licence.
What is still being tested
- A separately transmitting and receiving pair of devices. The bench results used the prototype's own returned signal.
- Fresh, non-repeating data. The continuous tests replayed a fixed table of codewords.
- Outdoor distances, moving targets, sunlight, and temperature changes. Current distance evidence covers up to about 6 m.
- Absolute range calibration. An unresolved scale offset of about 2.8% remains at this operating point.
- The Control stage of ISCC.

How to read the results
Measured refers to a recorded test under stated conditions. Simulation describes a software experiment. Projection describes an expected performance or proposed application. These are different levels of evidence; read the conditions alongside each number.
