While at it, they should also put up a pole every village (like electric pole) with high range WiFi router. This will remove the last 100m connectivity hurdle and everyone with a WiFi device can get a taste of high speed internet.
People will still the WiFi device and sell it for pennies. They don't spare road light in many parts of cities.
1000 days if substantially shorter than the lifecycle of phone models. New cheap phones today don't have 5g, you see the timing issue?
The limiting factor is the client. Maximum transmission power is limited by law to avoid interference; routers generally hit the maximum - mine is doing 1 watt on the 5 GHz band and 200 mW on 2.4 GHz. But phones and laptops generally transmit at no more than a few dozen mW.
Transmission and reception have asymmetrical link speeds but your range is going be bounded by the point at which the client can't reliably talk back to the router to keep the connection alive.
