Re: Mobile 5G
Interesting to read that one city had a range of about a football field while the second city had a range of about three times that. I wonder what geography or obstacles led to the differing distances. And will antenna design in comiing months improve on the consistency and range?

the first commercial 5G operator
Will AT&T be the first commercial 5G operator?

Re: Distance?
And 100 meters to 200 meters for mobile 5G but more on that later.

Re: Mobile 5G
They said 3GPP-based mobile 5G with a "mobile puck" as 1st device.

Re: Distance?
Yes, but Dan Jones is from a place where they drive on the opposite side of the road. So maybe he was schooled to go from higher to lower. Or maybe something something else. Cubits also can be problematic, because there are regular cubits and long cubits, which are slightly longer than regular cubits. You'd think something as precise as arithmetic and measurements would have been figured out by now.

Re: Distance?
My comment was because the way the article was written, it implied that 900 feet was the lower bound of achievable distance and 150 meters was the upper bound.  Mixing units of the same variable should always be avoided.

It should have read "500-900 feet" or "150-275 meters".

(or, for Mendyk, "180-600 cubits")
Duh!
Duh!

Re: Distance?
That was the only interesting tidbit.

The consensus of researchers seems to be intersite distance (ISD) of 100-200 M for mm-wave fixed broadband. 150 and 275m, respectively, aren't unreasonable, given what little they've disclosed about these experiments.

Re: Distance?
Yes -- it's about 275 cubits less.

Distance?
Isn't 150 meters far less than 900 feet?
