We develop Asymmetric Free Space Optical (FSO) data communication solutions, primarily for interacting systems in industrial facilities. In comparison to the "competing", or "additional", technologies such as radio frequency (RF) based datacom, an Asymmetric FSO link provides a high-speed and interference-free communication method which is almost impossible to intercept. Furthermore, the technology is energy efficient and, if implemented correctly, quickly installed. Our patented system have been designed in a way that also constitutes a reliable positioning system. Thus, the method can be used not only for data transfer, but also for achieving full traceability and full control of industrial operations.
