The mood in the 5G Arena at Hannover Messe is muted, same as last year. All the buzz and excitement about private / industrial 5G at MWC, which seemed almost to bubble-over in the tight-knit halls of the Fira de Barcelona, as the late winter sun broke through, is entirely dissipated in the wide open spaces of the Hanover Fairgrounds, where a little late-winter snow has started to fall. But it probably wasn’t there to start with. This is a different venue, and a very different show.
