in kerala airtel added 5mhz to b3 so overall b3 is 10 mhz here, but there is no sign of b8 they acquired in the auction. Also they are running 2g simultaneously on b8 and b3 here. , i think they should have deployed dss here on b8 so that it can be 10 mhz overall. Jio does not even bother to add spectrum here on any bands.
Is deploying 4g on band 8 is difficult, even vi is struggling to deploy b8 in my area.
