[LINK] Don’t believe the hype: We’re a long way from 5G

[Marghanita da Cruz]

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."

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.

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.

> 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.
