MUMBAI, India, Jan. 7 -- Intellectual Property India has published a patent application (202511103706 A) filed by Manipal University, Jaipur, Rajasthan, on Oct. 28, 2025, for 'automatic free space optical (fso) link alignment system for local area high-speed communication.'
Inventor(s) include Shreya Sinha; Aadarsh Kumar; Prof. Manish Tiwari; and Dr. Ankur Saharia.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to an economical short-range Free-space Optical link auto-alignment system for local area high-speed communication. The system comprises Arduino Uno R3 and a stepper motor regulated by an accurate controller; an economical wireless transceiver equipped with a 2.4 GHz antenna, facilitating communication across a distance of 100 meters in unobstructed space; and a 500mW 520 nm green laser and a 1.5V solar photovoltaic module for data transmission and reception. The system is evaluated at a range of 78 meters with an unobstructed line-of-sight, and beam dispersion is quantified up to 48 meters. The present system utilized for establishing optical links over shorter distances where the installation and upkeep of optical fibers may prove difficult and expensive. The proposed technology can be scaled for greater distances by utilizing more advanced components."
