Hi Jason,

Nokia did at a recent IETF hackathon showed a simulated 5G access network to
do low latency remote control of cranes in an industrial port facility. It
seemed like one of their points was that you could remotely operate cargo
container movements with the crane via a remote workforce over a low delay
network connection - even with fairly limited bandwidth (they’d adjust the
throughput down to just a few hundred kbps).

cranes at several ports around the world on an as-needed basis (vs. being
based in 1 port and having some downtime or low utilization of their
skills/training), even from the comfort of home.

 

 

      I would stop doing business with such ports... there clearly are
accidents (or sabotage/jamming) just waiting to happen using wireless
connections for such use-cases... Yes, I understand that that is what Nokia
sells, so everything looks like a nail to them, but really "caveat emptor",
just because something can be done does not mean it should be done as
well...

P.S.: Currently in the US for a conference, getting reminded how shitty
GSM/LTE can be, heck the conference WiFi (with 25K attendees) is more
responsive than GSM... I am sure 5G might be better, but my phone is LTE
only...

[RR] Welcome to the “club”!  We in the US have been dealing with this for
over 30 years … why you ask???? ... answer … CDMA and the IPR behind it!  It
was and still is “all about the money!”. My phone has 5G and when download
rates plummet to the floor, all I have to do is look at the top of the
display, and lo and behold … I’m on 5G!!! If you believe 5G is going to be
better, I have a bridge for you that “is going to be soooo much better”
:-):-):-)
