Ongoing Costs = Large elephant in little room on footpath.
I once read in an article about Turnbull's proposal for FTTN that it was estimated that the cost of providing power, servicing and ongoing maintenance would be $11B pa. In contrast the same ongoing cost for FTTP would be $2B.
The burden for ongoing costs in any system will fall directly upon the consumer. If this figure is accurate, the cost of Turnbull's NBN will double in 5 years of trouble free running. Another way to look at it this is that a FTTN network could have been bought and paid for by its customers in five years if true.
I don't know if the figures quoted are realistic or not. If only some tech-oriented media would pick up the cudgels.
