That's incorrect. Jio has already come out with high speed wired broadband called JioGigaFiber: https://jiofiber.co.in/. Poles have been erected in my locality and pretty much the entire city. It's way cheaper than the current broadband I'm using (Hathway) and I'll be shifting to it once it launches. Currently it's being rolled out in phases across the country: https://www.mysmartprice.com/gear/2018/09/06/jio-gigafiber-c...

"JIO GIGA FIBER will be the largest greenfield fixed-line broadband rollout anywhere in the world, with rollout happening in 1,100 cities of India simultaneously"
