What’s in a name? 5G wireless claims, but no real network

5G E? 5G Plus? 5G Ultrawideband? Will the real 5G please stand up?AT&T has drawn ridicule by relabeling the network used by some of its phones as "5G E" to signal that the next-generation wireless network is here. Problem is, phones capable of connecting to 5G aren't coming for another few months, and a national 5G network won't be deployed until 2020 or 2021.But Verizon, which complained Tuesday about AT&T's move, did something similar when it launched a residential wireless service with the 5G moniker using its own proprietary technology. Although there are now industry standards specifying exactly what 5G networks must meet, dubbed "5G NR," there are still some grey areas, particularly when it comes to marketing. Carriers are using all tools at their disposal as they race to try to convince consumers they'll be "first" with 5G.A new generation of wireless network comes along every several years, so the stakes are high for carriers to establish their dominance. When it's fully deployed, the "5G" network is expected to give mobile users faster speeds for video, self-driving cars and connected devices at home as demand for these ramps up.
