With the advent of mobile communication, India is contributing hugely to the massive escalation of global data volume, and by 2030, India's share may increase to one third or even more of the total data generated from standard mobile communication, Science and Technology Secretary Abhay Karandikar said on Sunday. ""We will have a variety of use cases, from very high to very low data rates, from very stringent latency environments to latency-tolerant applications, heterogeneous radio access technologies, and a range of access devices. This diversity in India will be a useful test scenario for cellular mobile communications and also devices connected through Wi-Fi, drones, satellites, terrestrial networks, sensors, and IoT,"" said Karandikar. However, he added that India still has a long way to go as far as research on standardization and filing patents is concerned.
