How does that help?

How does that help?

We think of things as far but are they really? We like to think the world is high tech but resort to basic tech like running a cable from one country to another. It helps to put things in perspective.

I see what you're saying, they should have some sort of transmitter that eliminates the need for a cable. Seems like the tech is either not yet available or it's too slow, or it's too expensive to set up.. I have no idea which one it falls into.

Wireless will never beat fibre optic cable for bandwidth capacity. End of story. That lack of knowledge of how data transmission works is why we have a second rate NBN now. The Liberal government pulled the old “wireless will make it obsolete” trick and everyone fell for it and voted for them.

People have the misconceived idea that wireless internet will make cable internet obsolete eventually when physics says it can’t. A fibre optic cable system can carry many millions of transmissions with zero crosstalk and interference.

Because it isn’t prone to interference and each signal doesn’t have to “share space” with every other signal in the vicinity by transmitting it through the air fibre optic cables will always be scalable far more than wireless ever could.

They dont build redundancy into the system. If redundancy happens to occur because of other economic incentives then that’s the best you’ll get.

Just have a look at Tonga who only just got their internet back after a month. No money in making redundancy so it doesn’t happen unless there’s another economic incentive.

Redundancy is indeed built into the system from the processing side, routing mechanisms and also with physical layout. Redundancy isn’t simply because of other reasons, it’s inherent in the systems design.

Sadly modern economics see less redundancy occurring in newer system which isn’t a great step forward in redundant design. NBN is a prime example where newer is less redundant, in that a local power outage kills most IP telephony and internet since the optic fibre modems (if you’re lucky) don’t always have backup power (and even less so in the alternates, FTTN, FTTC, etc). Contrast this to POTS where working phones during widespread power outage were the norm… working for days… And then there is the absurdity of emergency services drifting away from UHF and towards mobile systems, what can go wrong with such moves

In cases where multiple physical cable routes are cost prohibitive, or there isn’t a strong business case, as in a small island, redundancy (read multiple physical routes) isn’t great. But there is always some alternate traffic limited route, always (think satellite and such). Even in such cases with traffic limited routes, by definition it‘s still redundancy though it’s a poor implementation (unless your service has the correct flags so you can bump lower class traffic)…

And as for “economic incentives” I read that as government handouts to build a quality network cause unless they are forced to do it by government regs, etc, history shows business won’t… Just look at the **** that is the US internet markets and the shitfuckery they play in the courts to stop competition. Yet where the services are provided, there is redundancy built into most parts of the system…

Optic fibre is high tech by definition. May PPE not so much yje glass fibre but the way we’d send data down the fibre using TDM, FDM and WDM methods… It is high tech by its nature, in much the same as the way that playing with radio frequencies is high tech ( after all light is a wave… or is it a particle… or is it a wave )
