5-6Ghz, certainly, lower frequencies do though. This is why T-mobile offers home broadband using their 5G network (which can support up to 1M devices per square km) in the US; they overbuilt, and have many smaller cells with lots of capacity and are undersubscribed, and monetize the remaining capacity using lowest priority fixed broadband.

One could see India deploying the same density compatible infrastructure in the usual "leapfrog" model of skipping lesser technology implementations in this space.
