The whole point of UFB/RBI project seems to be missed by some - it is a subsidy for urban and rural networks.
There is subsidisation in the urban network - those in urban location who had poor broadband have had their network upgrades subsidised by others some of whom saw no need for it and were/are quite happy with ADSL/VDSL speeds.
If you follow some of the logic expressed here then mobile call/data rates should differ depending on the true cost of connecting to a particular cell site and a consumer connecting at the end of a fibre run should pay more than someone living next door to the exchange but in reality the cost is averaged out across the whole network as follows - "UFB1 Cost Per Premises Passed $1,500 - $1,600 [and] UFB1 Cost Per Premises Connected $1,000 - $1,150". I would like the same principle applied country wide and see the urban/rural distinction removed.
Re backhaul "backhaul from the RBI cell towers [is] subsidised" see
Data and voice (and SMS/MMS) are quite different products, so you can't really compare the pricing between them like that.
