[LINK] NBN: Simplistic Arguments

> Twitter was abuzz with "NBN out of date" tweets saying that "5G was here" & lauding the 1Gbps speeds (over 2km mind you) as an "fibre  killer". Sadly, these people were wrong. The oversimplification by many news outlets to describe the new interface as 5G was wrong. Not just a little wrong, but completely wrong.

....

> If we look at the BT's deployment, even Sydney (~2000/km²) or Melbourne's (~1500/km²) population density doesn't compare to the top 136 cities in the UK, with the top 120 being more than double that of Melbourne.

.....

> Looking at Deutsche Telekom we can see similar, albeit less stark, contrasts between Australia & Germany: higher population densities,  low attenuation copper, & a network that has already had heavy investment over the last decade. Something interesting to note is that  when DT deployed their FTTN network to 10 million customers (just 2 million more than the Coalition's plan intends to connect), they needed to build 330 000 nodes. Yes, that's 5x the number Turnbull intends in a country where the urban population density is more than double that of Australia. The reason for doing so was to keep loops short enough to support 25Mbps services, as Turnbull wants to do.
