Nonsense! There is no 5G. There isn't even an agreement between the various parties as to what 5G will be.
In fact, we don't have 4G anywhere around the world yet. LTE is not 4G. Several years ago, when 4G fell well behind schedule, carriers and manufacturers lobbied the 4G working committee to allow them to call LTE 4G. After 6 months, the committee agreed. But LTE is actually 3G+. 4G is LTE Advanced, which has been in testing stage for several years, and is something we won't see for another year, at least, in commercial installation.
Estimates for the release of 5G, is mid 2020s, with some in the industry thinking early 2030s.
So,what AT&T and Verizon, who also announced this, are likely talking about is LTE Advanced, in other words, real 4G.
Don't let anyone fool you guys about this. No one even knows what 5G will be. Some groups want it to be equivalent to 10G Ethernet. Some want it to be a mesh technology, and others want it to be LoT. There is No agreement as to what it will be, much less having equipment capable of delivering anything.
