> Forget all those stories of 20 Gbps speeds and 1 millisecond latency. 5G will never deliver performance like that — and anyway its time is still years away for most of us most of the time.
...
> What we do know is that 600MHz 5G will cover limited areas. What you think of as 5G, with all the speed and fancy trimmings, will have a range of a few hundred yards — if we’re lucky.
>
> Oh, and when you’re inside, you’ll want to stay close to the windows. That’s the only way you’re going to get a signal.
>
> That’s because the millimeter wave (mmWave) 5G that AT&T and Verizon are bringing us has no range or penetration to speak of. 4G, in comparison, has a practical range of about a dozen miles.

> There are a couple of problems with this. First, they will need to get permission to put all those femtocells, which are about the size of microwave ovens, in place. Then they must hook them up to fast fiber cable to deliver 5G speeds — because, as always, a network is only as fast as its slowest link. And, finally, they have to actually install the femtocells.
