Millimeter-wave 5G will never scale beyond dense urban areas, T-Mobile says


Source: ARS Technica



5G mobile networks have started arriving but only in very limited areas and amidst misleading claims by wireless carriers.

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." That would seem to rule out the possibility of 5G's fastest speeds reaching rural areas or perhaps even suburbs.

Ray made his point with this GIF, apparently showing that millimeter-wave frequencies are immediately blocked by a door closing halfway while the lower 600MHz signal is unaffected:



Cont'd.
