5G trials sites were established by Bharti Airtel, Vodafone Idea and Reliance Jio in select cities in 2021. Some of the first cities that are likely to get 5G connectivity will be Mumbai, Delhi, Bengaluru, Gurugram, Chennai, Hyderabad and Kolkata among others.
5G is said to offer much higher speeds of Internet connectivity and connect many more devices other than smartphones.
Eight agencies – Indian Institute of Technology (IIT) Bombay, IIT Delhi, IIT Hyderabad, IIT Madras, IIT Kanpur, Indian Institute of Science (IISC) Bangalore, Society for Applied Microwave Electronics Engineering & Research (SAMEER) and Centre of Excellence in Wireless Technology (CEWiT) – are involved in the research project called ‘Indigenous 5G Test bed project’.
The Indigenous 5G Test bed project started in 2018 and is set to be completed by December 31, 2021. The project has been funded by the Department of Telecom. The department has spent Rs224 crore on this project.
5G mainly works in 3 bands, low, mid, and high-frequency spectrum. In the low band spectrum, the speed is limited to 100 Mbps (Megabits per second). The mid-band spectrum, on the other hand, offers higher speeds compared to the low band but has limitations in terms of coverage area and penetration of signals. Internet speed in the high-band spectrum goes up to 20 Gbps (giga bits per second). The highest internet speed in 4G has been recorded at 1 Gbps.
While 4G networks are mostly designed for phones, 5G networks is designed for much more flexible use, replacing the need for many special-purpose networks. They can even function as many separate networks – all at the same time.
