You’re right but….
This doesn’t make any sense as a product! 5G as a protocol gets identical performance to 4G as a protocol, indoors where the physics forces you to use that radio band. 5G gets very high data-rate and low-latency outdoors, by using mmWave, precisely in locations where there’s no interest in either watch UHD movies or AAA gaming, when you might actually want it.
There’s zero advantage to being “5G” per se. There might be some advantage to adding mmWave capability. But just adding a couple of new radio bands has *never* required a whole new “G” in the history of 3GPP. Usually, radio band doesn’t even count as a Release upversion, which happens every year or two, it’s just a UE capability in a matrix defined *within* a 3GPP release. Why is *this* capability being raised as so significant compared to: number of UE antennae, number of MIMO layers, HARQ, BWP switching delay, or any one of half a dozen other UE radio capabilities?
