The Centre for Development of Advanced Computing (C-DAC), Chennai, under the Ministry of Electronics and Information Technology (MeitY), signed a Transfer of Technology (ToT) agreement with Nav Wireless Technologies Pvt—Ltd on 28.11.2024 for its cutting-edge technologies, NLOS VICINITY and ILLUMINATE.  

Scope of work 

The agreement facilitates the transfer of cutting-edge technologies, NLOS VICINITY and ILLUMINATE, to Nav Wireless Technologies Pvt. Ltd. for deployment and commercialization. This partnership highlights the immense potential of public-private collaboration in fostering technological innovation and contributing to economic growth. 

Sh. S. Krishnan, IAS, Secretary, MeitY

He lauded the efforts of C-DAC and Nav Wireless Technologies to drive innovation through public-private collaboration. He highlighted the transformative potential of the NLOS VICINITY and ILLUMINATE technologies, emphasizing their low cost, fast gestation, and wide applicability.  

The Technologies

The C-DAC, Chennai has developed two Visible Light Communication solutions, namely, (i) A Non-Line Of Sight Approach for Visible Light Communication Indoor PosITioning SYstem (NLOS-VICINITY) and (ii) VIsibLe Light CommUnication enabled Smart Indoor LightiNg And Control System (ILLUMINATE).  

NLOS-VICINITY represents a leap forward in indoor positioning technology ideal for smart proximity advertising, indoor location-based services, and indoor navigation. ILLUMINATE takes indoor lighting control to a new level of intelligence and sustainability for use in RF-free zones. 

The USP

Visible Light Communication (VLC)/Light Fidelity (Li-Fi) uses light waves instead of traditional radio waves to transmit data, offering unprecedented advantages such as faster speeds, enhanced security, and greater energy efficiency. Recognized as a transformative alternative to Wi-Fi, Li-Fi is ideal for applications ranging from smart cities to secure military communication. Its ability to provide high-speed data transfer with minimal electromagnetic interference is poised to redefine the landscape of wireless communication.
