D eepak Solanki, the co-founder of start-up venture Velmenni Research and Development Private Limited , is one of the pioneering figures in the ever-evolving space of Light Fidelity (Li-Fi) technology in India today.
What is Li-FI?  In simple terms, Li-Fi is a technology for seamless wireless communication between devices using a light source like LED bulbs to transmit data. It is widely believed that Li-Fi technology can deliver internet speeds that are 100 times faster than conventional Wi-Fi. Solanki, however, argues that this isn’t necessarily accurate. “Li-Fi has the potential to achieve speeds in the range of 10s of Gbps (gigabits per second),” says Solanki. 
Before Li-Fi From dial-up to broadband and finally Wi-Fi, the internet has dramatically evolved in terms of the volume of information available online and the speed at which one can access it. “Traffic from wireless and mobile devices will account for more than 63% of total IP traffic by 2021,” says this Cisco study. 
Each of our devices will be connected to the internet, as we move into the Internet of Everything era. From vehicles sending out traffic-related information to sensors on a field delivering real-time information about soil quality, the internet is further extending its influence on humanity.
Is Wi-Fi up to the task of handling all that internet traffic? The short answer is no. What Wi-Fi essentially does is use radio frequencies to transmit wireless data. With the number of wireless devices (laptops, smartphones, or different kinds of sensors) increasing exponentially, the limited amount of spectrum is a real concern. There are security-related concerns as well, but the biggest challenge is limited bandwidth. Hence, the need for an alternative mode of communication.
Early days Twenty seven-year-old Solanki was born and brought up in the city of Jind, Haryana. As the son of a government school teacher and housewife, Solanki grew up with a real passion for science and technology, especially robotics. After finishing school in Jind, Solanki went onto pursue engineering at Lovely Professional University in Jalandhar, Punjab.
What cemented Solanki’s interest in technology was an internship in the Robotics Research Lab at IIIT-Hyderabad. He worked there as a research intern, and in his words, “motivated me to continue to work in the domain of scientific research.”
How did Solanki first encounter Li-Fi? After working in a robotics start-up at IIT-Bombay  in 2011, he moved to Delhi in March 2012. By September 2012, however, he had formally registered Velmenni Research Developmen  t as a sole-proprietorship business.
“I wanted to start my own venture because I figured out that it takes a lot of time to develop and make anything in product form. I wanted to make real products. I had a keen interest in wireless communications. I have worked on radio frequencies, and am a HAM Operator (he holds an amateur radio license). So, after starting the company, my first area of interest was wireless technology. It was then when I came across Li-Fi/Visible Light Communication and found it rather fascinating,” says Solanki.
