We keep hearing about 5G mobile networks arriving in very limited areas and it having misleading claims by carriers. What about T-Mobile? T-Mobile is being honest, T-Mobile’s CTO, 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.” Which means that will rule out the possibility of 5G’s fastest speeds reaching rural areas. Ray also goes over the 5G launches we’ve seen from Verizon and AT&T are spotty and that performance is highly variable. These problems are going to be difficult for carriers to solve.
