Signal Range of ONT provided by Airtel as compared to Jio's Router?

Thinking to buy Airtel broadband connection plan.Really appreciate it if someone can tell me how is Airtel's ONT signal range as compared to Jio Router?

@rameshbritto I have the Jio white router that was given initially and on Airtel, i have the Nokia 2425G Router. In comparrison, Nokia offers a tad better range on 5Ghz but that could be attributed to the Channels or 80hz band that Nokia works. However, you're a better off buying your own router if you want best of the coverage. These provider Routers are always a make or break deal.

Nokia's 5GHz range is much better.
