Can someone who is a domain expert comment on this statement I see being repeated often about Jio's ability to have a significantly lower cost structure by offering only 4G service with 'commodity hardware' versus the legacy players who are operating 2G/3G networks in conjunction with 4G? Is there a lot of truth to this or is this just something that the analysts have heard someplace and are now repeating it faithfully?
It is true. The ex-CTO of Jio, Tareq Amin, who pioneered this IP only network in Jio now works for Rakuten in Japan and he repeated the same feat here in even lesser time. You can lookup terms like NFV and Open-RAN to dig deeper. If you're familiar with web-infra it's similar to replacing expensive hardware routers from Cisco with a simple dumb server + FRR
