The rollout of 5G has proven to be at least as interesting as the technology itself.  We've seen companies roll out somewhat less than accurate service names, to a major shift in the modem industry even before we could get our hands on a true 5G device and connect it to a 5G network.  It will also create some unforseen difficulties for meteorologists. Today, T-Mobile Chief Technology Officer Neville Ray suggested that the full range of signal available to 5G networks will never be rolled out beyond small pockets of major cities. 

This is not to say that 5G will not be widely available, the low frequency portion of the new standard will have coverage equal to current 4G networks however it is the high frequency bands that will offer the fastest service and as they are easily blocked by any obstructions they will be very short ranged.  That will limit the higher speed versions of 5G to small areas in large cities where you can get a clear line of sight to a tower.  Ars Technica has posted a good look at why this is in their latest article.

"5G networks will use both low and high frequencies, but they're supposed to offer their highest speeds on millimeter waves. Millimeter-wave spectrum is usually defined to include frequencies between 30GHz and 300GHz. "
