What is 5G?
- 5G or fifth generation is the latest upgrade in the long term evolution (LTE) mobile broadband networks.
- The first generation of networks allowed only mobile voice calls to be made.
- The second generation allowed mobile voice calls as well as sending of short text messages.
- It was the third generation or 3G network which allowed web browsing on mobile devices.
- The speed and latency of which improved with fourth generation or 4G
- The 5G networks will have even faster speeds with latency down to between 1-10 milliseconds.
How does 5G work?
- All 5G networks chiefly operate on three spectrum bands.
- The low-band spectrum has been proven to have great coverage but the maximum speed limit on this band is 100 Mbps.
- In the mid-band spectrum, though the speeds are higher, telcos across the world have registered limitations when it comes to coverage area and penetration of telephone signals into buildings.
- The high-band spectrum offers the highest speed but has extremely limited network coverage area and penetration capabilities.
- The telcos using this band rely on the existing LTE networks and will need to install a number of smaller towers to ensure adequate coverage and high-speed performance.
- Announced that the company’s telecom venture Jio has designed and developed from scratch, a complete indigenous 5G solution ready for deployment.
- It will enable Jio to export 5G solutions to other telecom players globally.
Where does India stand on 5G?
- Both telecom service providers and their equipment vendors, have completed lab trials of 5G network components,
- But are yet to commence field trials, which were initially scheduled to happen last year.
- The service providers have already tied up with equipment makers like Nokia, Ericsson, etc for deploying their 5G networks.
- Also telecom companies are awaiting allocation of test spectrum from the Department of Telecommunications (DoT).
Jio’s 5G solution
- Jio is said to have a complete end-to-end 5G solution prepared by the company itself that is ready for deployment once the networks are in place.
- This solution can also be deployed by other telecom operators as a complete managed service.
- When Reliance announced investment by American chipmaker Qualcomm into Jio, it had said that the investment will deepen the ties between
- Qualcomm and Jio Platforms, “to support Jio Platforms on its journey to rollout advanced 5G infrastructure and services for Indian customers”.
- Additionally, with Google’s partnership, Jio plans to develop affordable smartphones using an optimised Android-based operating system.
