Guwahati: An innovative free-space optical communication system has been transferred to the telecom industry by the Indian Institute of Technology Guwahati.
An official announcement claims that the sophisticated communication technology uses wavefront modulated light beams rather than optical fibre for wireless error-free data transmission via free space.
The technique 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, 2021and Korea on December 28, 2022.
Speaking about the technology transfer, Prof. Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati, said, “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 meeting the challenges as our technology is adapted to serve society.”
The study team has experimentally proven that text messages and images can be transmitted without distortion both within and outside of a lab, even when there is turbulence.
With virtually little chance of unauthorised interception, the communication system can be used for fast, secure communication between two distant stations in line of sight.
In collaboration with the Ministry of External Affairs (MEA), Research and Information Systems (RIS) New Delhi and the North East Training and Research Advocacy (NETRA) foundation, the “G20 – University Connect” programme with the theme “Building Bridges to achieve SDGS” was launched from IIT Guwahati on January 28.
In order to raise awareness among university students regarding the G20 and its objectives, a pre-event quiz was held in which more than 200 students took part. For an internal panel discussion with dignitaries and experts, 50 students from various universities and fields were invited. In hybrid format, almost 100 students from several universities took part in the live event online.
