“Raised by books.”

I, Jagdeep born in a small city Khanna of Punjab, India. I did my schooling from my native place. During my school days, I was more inclined towards my academics, with my love for books far exceeding that for sports. I had a very clear picture that I want to pursue Science and Mathematics. Looking at cells under a microscope was more appealing to me than a cricket ball. With a knack for tinkering, enrolling in engineering was a no brainer. I did my graduation in Electronics & Communication Engineering from a Government State University, “Guru Nanak Dev University, Amritsar.” During graduation, I worked on a wide range of projects, ranging from Embedded Systems and Microprocessors to Networking, that helped me gain a better understanding of my area. Because I liked my area, I was always academically motivated and was among the top 5% of the class throughout my undergraduate. At the end of my graduation, I got a job in a private consulting company. However, my interest didn’t align well with doing a fixed time-bound job with tasks with fixed guidelines. I wanted to explore & research new things, new ideas, and wanted to do something that people will value.

After graduation, with a lot of hard work, I cracked the Graduate Aptitude Test in Engineering  (GATE) exam. I got admission to one of the top engineering institutes of India, “Indian Institute of Technology, Delhi," where I completed my Masters in the area of Joint Optoelectronics & Optical Communication. During my Masters, I focussed my work in the area of optical wireless communication, specifically on visible light communication (VLC). My thesis, titled “Modulation and Multiplexing Techniques in Visible Light Communication,” had a perfect mix of both theoretical analysis and simulation-based experimentation. After my Masters, I extended this idea to the real-world setting by designing a testbed for LiFi technology while working as a Project Engineer in an Indian Government-funded “LiFi Networks” project at Electrical Department, IIT Delhi. Moving from a simulated setting to a real-world environment was a big challenge, and this project helped me understand how to bridge that gap. Besides the technical growth I have undergone during my masters, I have also played key roles in various institute level student bodies. Presently, I am extending my research interests and exploring more about VLC technology by doing a Ph.D. in this domain. My Ph.D. research project is on the “VLC-BLE based indoor positioning system,” which is funded by the European Union (EU).

Interests: In my free time, I love to watch TV series, enjoy some cooking and play badminton sometimes. I do like to travel and meet new friends.

I firmly believe that the only problems worth solving are the ones that hit you back.

My project is to design a “VLC-BLE based indoor positioning system” with decimetre level positioning accuracy. These two technologies are better in one sense and not in others like the VLC can provide a high accuracy positioning system compared to BLE; however, BLE can give a highly energy-efficient positioning solution. The idea of this project is to design a new hybrid positioning system for large indoor public spaces such as supermarkets, retail stores, and warehouses, etc., by combining both technologies that will exploit the accuracy of VLC and the energy efficiency of BLE. Factors that limit the commercial viability of today’s VLC-based localization include a) the need for significant changes in luminaire design to modulate the transmitted light, which incurs a considerable deployment cost. b) the use of energy-inefficient general-purpose cameras as VLC receivers. The project work will involve identifying the minimal set of hardware changes required on both luminaires and handheld devices to increase the energy efficiency of the handheld devices while improving the positioning accuracy.
