Interesting interview from this morning with
John Lord (Chair, Huawei Australia is now available for download
"Huawei denies any "material" links with the Chinese Communist Party and
says its best placed to deliver the high tech equipment needed for the
5G rollout."

As an example, consider these guys - https://phantom.auto/ They provide a
solution to handle the corner cases where your self-driving car can't handle
whats in front of it (roadworks, weather, etc). They can take over the driving
of the car remotely for the short time it's needed. But to do that they need
high bandwidth, low latency communications. Whilst 4G might be enough in some
cases, in a more general sense it isn't.
I'll believe self-driving cars when I see the first models with no manual controls
approved for normal use on Australian roads, or at least no requirement for monitoring by
a "driver".
However there's an important point here which isn't specific to that use case. If
these vehicles rely on continuous 5G and GPS availability, especially if it
involves communication with nearby vehicles (not all of which will be driverless)
or some other entity, then the level of total system complexity will be very high.
And that makes it vulnerable. Remember the chaos on Sydney roads when an
over-height truck gets stuck in a tunnel? And that's a simple example where both
the cause & solution are physically obvious.
There's a relationship between complexity and vulnerability, though it has to
be said measures of system complexity are not simple.
Or TV Broadcasting. I'm sure you've seen the trucks pull up with the satellite
dish on it and take 30 mins to get setup. No longer needed - just use 5G.
But that's not even the tiniest component of a cost justification.
Or football stadiums. 4G simply doesn't work well when 40,000 people are all
trying to tweet and live-stream the try that just happened. (OK, so maybe 5G
is a bit about mobile devices)
Neither is that IMO. Why don't they watch the replay on the big screen? It
will be showing exactly the same images they might see on their mobiles.
I was at the GITEX expo in Dubai a few months back where they were demoing 5G
technology. One of the demos was using 5G for remote robotic surgery. This
ins't exactly new, and can be done today without 5G, but the lower latency of
5G apparently improves things dramatically.
I'd like to see the cost-benefit of remote robotic surgery of any sort; the
patient had better hope there's no network outage! As I remarked above,
greater complexity leads to greater vulnerability. In fact there seems to be
no medical consensus that robotic surgery is generally better than hands-on
surgery anyway, and it's very expensive.
