Learners enrolled: 213
Optical Wireless Communications (OWC) has become a promising technology for supporting high-data-rate 5G communication and the massive connectivity of IoT. This course broadly covers the four important aspects of OWC systems: (a) the fundamental principles of OWC, (b) devices and systems, (c) modulation techniques and (d) channel models and system performance analysis.The course also covers different challenges encountered in OWCs as well as outlining possible solutions and current research trends. The course will also involve MATLAB® simulations to help students understand the topic under discussion and to be able to carry out extensive simulations.

Instructor bio

Prof. Anand Srivastava

IIIT Delhi
Prof. Anand Srivastava did his M.Tech. and Ph.D. from IIT Delhi and is currently working at IIIT Delhi as Professor in ECE department since Nov. 2014 and also Director at IIIT Delhi Incubation Center (a Section 8 company). He is also Adjunct faculty in Bharti School of Telecom Technology at IIT Delhi. Before joining IIIT Delhi, he was Dean & Professor in the School of Computing and Electrical Engineering at Indian Institute of Technology Mandi, HP, India from Jan. 2012 to Nov. 2014. Prior to this, he was with Alcatel-Lucent-Bell Labs, India as a solution architect for access and core networks for 2.5 years. His initial stint (∼ 20 years) was with the Center for Development of Telematics (CDOT), a telecom research center of Govt. of India where he was Director and member of the CDOT Board. During his stay in CDOT, he provided technical leadership and motivation to a team of engineers engaged in the development of national-level projects in the areas of Telecom Security Systems, Network Management Systems, Intelligent Networks, Operations Support Systems, Access Networks (GPON) and Optical Technology based products. The majority of these projects were completed successfully and commercially deployed in the public telecom network. He also carried out significant research work in the Photonics Research Lab, Nice, France, under the Indo-French Science & Technology Cooperation Program on “Special optical fibers and fiber-based components for optical communications” during 2007-2010 in different phases. He was also closely involved with ITU-T, Geneva in Study Group 15 and represented India for various optical networking standards meetings. Currently, he is driving VLC/LiFi standardization activities under the aegis of TSDSI. His research work is in the area of optical core & access networks, Vehicle-to-vehicle communications, Fiber-Wireless (FiWi) architectures, and Visible light communications.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 29 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Madras. It will be e-verifiable at nptel.ac.in/noc.
