No idea if anyone noticed it yet, but Jio has mentioned Jio GigaFiber as Jio Fiber everytime in their today's AGM and tweeting all tweets with #JioFiber hashtag. All that hints towards a product name change. They have dropped the word Giga before launch.
Jio has changed name of GigaFiber broadband to JioFiber but why Why is it called JioFiber and not Jio GigaFiber?
We don't know the exact reason but it seems that Jio wanted to simplify the entire naming convention of the service. The broadband, TV and landline service rely on Jio's fiber network and hence, selling a subscription to the entire package makes more sense than anything else. It is similar to upgrading a computer - you have a base computer and you can upgrade the graphics card if you want to play games or upgrade the monitor if you want to watch movies.
The fiber network will host the broadband service and if subscribers want the TV service, they can simply purchase the set-top box - no more additional connection required. The set-top box will rely on the same connection as the broadband service. Even the Jio Home Phone landline connection will rely on the same fiber network. All these services will rely on data from the fiber network and hence, the entire service is called JioFiber.
