Millimeter-wave 5G will never scale beyond dense urban areas, T-Mobile says
Found on Ars Technica on Monday, 22 April 2019
While all four major nationwide carriers in the United States have overhyped 5G to varying degrees, T-Mobile today made a notable admission about 5G's key limitation. T-Mobile Chief Technology Officer Neville Ray wrote in a blog post that millimeter-wave spectrum used for 5G "will never materially scale beyond small pockets of 5G hotspots in dense urban environments."
Despite Ray's realism about the limitations of millimeter-wave signals, T-Mobile hasn't shied away from exaggerating the benefits of 5G.
No, 5G will not be the next saviour, despite what marketing guys preach. It is just a wireless network with shortcomings that should be treated as such. Don't fall for the propaganda.
