An innovative free-space optical communication system has been transferred to the telecom industry by the Indian Institute of Technology Guwahati.

Instead of using optical fiber for wireless error-free data transmission, the advanced communication system employs wavefront modulated light beams.

The technology was created by Dr. Santanu Konwar, an assistant professor in the department of physics at Abhayapuri College in Assam, and Prof. Bosanta Ranjan Boruah from the physics department at IIT Guwahati.

It is important to note that the technique is protected by patents issued in the US on June 2, 2020, Japan on December 23, 2021, and Korea on December 28, 2022.

The research team has experimentally proven that text messages and images can be transferred without distortion both within and outside of a lab, even when there is turbulence.

With virtually little chance of unauthorized interception, the communication system can be used for fast, secure communication between two distant stations in line of sight.

Prior to this technology, IIT Guwahati developed a novel free-space optical communication system for information transfer.

Free-space communication, which is the newest advancement in communications technology, uses light instead of optical fibers to wirelessly transport data in the form of voice, text, or images.

Speaking on the current occasion, Prof Boruah says that, “Free space optical communication is likely to play a crucial role in the coming days both in case of indoor applications and outdoor especially in the defence sector. We will be looking forward to meet the challenges as our technology is adapted to serve the society.”

Hardik Soni, co-founder, Nav wireless Technologies Pvt Ltd, adds, “NavTech is the pioneer and leading technology company in India doing research on optical wireless technologies – LiFi|FSO, developing applications, and manufacturing LiFi & FSO products and solutions. We are glad to join hands with one of India’s premier technology institutions for further development of optical wireless technology.”
