IIT Guwahati transfers free-space optical technology to telecom industry
Indian Institute of Technology Guwahati has recently completed the transfer of technology (ToT) of a Novel Free-Space Optical Communication System to Nav Wireless Technologies Pvt. Ltd.
The advanced communication system uses wavefront modulated light beams for wireless error-free data transmission through free space rather than through optical fibre.
Prof Bosanta Ranjan Boruah has developed the technology Department of Physics, IIT Guwahati, and Dr Santanu Konwar, Assistant Professor, Department of Physics, Abhayapuri College, Assam.
The technology has been granted with US patent 10,673,525 dated June 2, 2020, Japanese patent JP, 6998868 dated Dec 23, 2021, and Korean patent 10-2483858 dated Dec 28, 2022.
Regarding the technology transfer, Prof. Bosanta Ranjan Boruah said, “Free space optical communication is likely to play a crucial role in the coming days both in the case of indoor applications and outdoor especially in the defence sector. We will look forward to meeting the challenges as our technology is adapted to serve society.”
The research team has experimentally demonstrated the distortion-free transmission of text messages and images in a laboratory environment, even in turbulence and outside the laboratory.
The communication system can thus be used for high-speed and secured communication between two remote sites in the line of sight with virtually no possibility of any unauthorised interception.
Speaking on occasion, Hardik Soni, CTO and Co-Founder of Nav wireless Technologies Pvt. Ltd., said, “NavTech is the pioneer and leading technology company in India researching 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 to develop Optical Wireless technology further.” Guwahatiplus
