Context

  • The Department of Telecommunications (DoT) has sought inputs from telcos and other industry experts on the sale and use of radio frequency spectrum over the next 10 years, including the 5G bands.

What is 5G technology?

  • 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
  • 5G mainly works in 3 bands, namely low, mid and high frequency spectrum — all of which have their own uses as well as limitations.

The current status in India

  • The low band spectrum has shown great promise in terms of coverage and speed of internet and data exchange, the maximum 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.
  • The high-band spectrum offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
  • Internet speeds in the high-band spectrum of 5G has been tested to be as high as 20 Gbps (giga bits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.

Where does India stand in the 5G technology race?

  • On par with the global players, India had, in 2018, planned to start 5G services as soon as possible, with an aim to capitalise on the better network speeds and strength that the technology promised.

What is the global progress on 5G?

  • More than governments, global telecom companies have started building 5G networks and rolling it out to their customers on a trial basis.
