India plans to roll out state-of-the-art 5G telecom services in the next four years, a senior official said, as the nation rushes to catch up with its Asian peers.

"We are not there yet," Telecom Secretary Aruna Sundararajan said in an interview in New Delhi, adding that the complete rollout of 5G will be done by 2022. "5G won't be driven by supply, it'll be driven by demand and the rest of industry needs to wake up to this."

The South Asian nation, traditionally a laggard in embracing the latest technology in telecommunications, will follow South Korea, Japan and China, countries where 5G service will be offered within the next two years.
