GUWAHATI: The 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 wave-front modulated light beams for wireless error-free data transmission through free space rather than through optical fiber. The technology has been developed by Professor Bosanta Ranjan Boruah, Department of Physics, IIT Guwahati, and Dr. Santanu Konwar, Assistant Professor, Department of Physics, Abhayapuri College, Assam. It is worth mentioning that the technology has been granted US patent 10,673,525 dated June 2, 2020; Japanese patent JP, 6998868 dated December 23, 2021; and Korean patent 10-2483858 dated December 28, 2022. Speaking about the technology transfer, Professor 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 indoor and outdoor applications, and especially in the defence sector." "We are looking forward to meeting the challenges that will arise 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 the presence of turbulence and also outside the laboratory. Thus, the communication system can be used for high-speed, secure communication between two remote sites in line of sight, with virtually no chance of unauthorised interception. Speaking on the occasion, Mr. Hardik Soni, CTO and Co-Founder, Nav Wireless Technologies Pvt. Ltd., said, "Nav Tech is the pioneer and leading technology company in India doing research on optical wireless technologies (LiFi and FSO), developing applications, and manufacturing LiFi and FSO products and solutions.", stated a press release.
