I have a friend who is using Jio AirFiber, and wants to shift to Airtel, but 5G is not available in his area. Hence he will stay with Jio to see if their services improve.
He says he is facing buffering and slow speeds.
Apart from that i feel JioAirFiber Max uses a high gain ODU/Anternna that reduces noise, hence the reason for fiber like low latency.
I hope Airtel gets better in its AirFiber tech, and provides the same latency in future by refining its infrastructure and hardware support.
