Nice thing in India is that all the major providers grey-legally put optical fiber everywhere, so you get FTTH or fiber to the street no matter what. In cities where the development authority is competent, it's slower as they actually have to get approvals and stuff. And in some places they use the 26Ghz band (technically part of 5G) for "air fiber" which is basically a wireless link from the roof of an apartment to a nearby line-of-sight base station. It gives good bandwidth as there is no interference with usual mobile data as that band never ended up working in practice without clean LOS.
