TV Channels will be from Dish antenna only.
This is actually the good thing I like about Airtel, it will not consume your internet speed while watching the TV Channels.
Also with Airtel you will be getting around 50 Mbps if you choose 40 Mbps plan.
Guys, don't drive the thread with further off-topic posts. You can discuss about Airtel AirFiber, internet plan speed, Airtel Axis Credit Card etc. on appropriate threads present on OnlyTech forums.
