Spectrum is finite though. You can add more fixed clients by adding more hardware at the CO and running more fibre. Eventually, even if no one is even actively downloading, your cellular network will saturate just from the number of clients. The same is true of wireless networks today. An 802.11n wifi network is also limited by the number of clients, even if none of them are consuming their share of bandwidth.

Assuming omnidirectional antennas. If you aim well enough, that finite spectrum is only shared by a handful of clients.

You could go even further and construct some kind of copper tube to send your radio signals down.

For most customers, current bandwidth is fine usually(and even in the countries with highest monthly download, the average is 10GB/month), so this is less interesting. But this network has a an order-of-magnitude larger theoretical cell capacity and since most costs are infrastructure costs, cost-per-GB for carriers should be 5x-9x lower.

Given how much more abundant it is on the wired side, and the fact they're all now introducing caps - no. The only way to increase profits when you're a monopoly is to charge more money for your product. The only way to do that when there's no ACTUAL scarcity is to create artificial scarcity through caps.

Epic read – and makes me wonder how long fixed services can truly survive. These kinds of speeds with little infrastructure surely scale better for those making the money, and are easier to implement for consumers too.

As long as latency still matters. Gigabit wireless service can certainly be usable for a broad range of consumer applications, but you still have people playing online games, streaming, etc. that are heavily impacted by latency. Personally, I wish I could get a decent 100/10 fiber connection in my area just for the latency advantages over DOCSIS alone (it takes roughly 10ms to even get out of my ISP's internal networ…

Modern LTE latency is comparable to DSL/Cable at <=30ms in many cases. Sure fiber latency is lower, but until that is available to the same amount of people as DSL/Cable the mobile technology will have advanced too. Online gaming and streaming is totally fine over a LTE connection, the only problem is bandwidth caps. (This might not apply to professional gamers, but i consider those a niche)

The router shown has a (not enforced) 20GB data cap - so you can blow through it within minutes :)

theoretical max of service 1Gb/s: (20 gigabytes) / (1000 megabits/second) = 160 seconds reported maximum in testing from article 400Mb/s: (20 gigabytes) / (400 megabits/second) = 400 seconds

When Telstra cable was first released in the 90s it had a 100MB cap and 130Mbit speed, so you could blow your $150+ monthly plan in seconds (and many did)

Does it? It seems like they just have more available spectrum. 4x4 MIMO and 64bitQAM help, but not an order of magnitude in practice.

The impression I get is that Telstra lobbied pretty heavily for an essentially hobbled fixed-line network. The reasoning is pretty simple: the ACCC stepped in in the early 2000s and gave access to Telstra exchanges for putting in their own hardware (DSLAMs) to provide ADSL service. As a result Telstra (IMHO) decided that fixed line was a loser so focused on 3G/4G as a profit driver since there was competition there (…

So that explains why Telstra has been doing so well and why Foxtel had so many buyers lining up for it! /s

30ms is abysmal.

This makes sense. Telstra's backhaul for fibre and cable customers is very lacking. They have oversold their bandwidth and suffer lots of congestion during peak times.

Take a look at this: https://www.theregister.co.uk/2015/08/10/telstras_netflix_do...

Why run a copper tube kilometers when a point to point microwave will be way cheaper?
