I call bullshit... on the economical level for the end user.
They said all of those wonders of 4G... and nope.
They charge 4G through the nose, for a paltry 5GB per MONTH on my mobile connection. If you burn through it, you're out until next month.
On my cabled DSL I get to watch Netflix, or someone at home does, for several hours on end every day. 8GB is barely a single HD movie, (well maybe two, to be honest). I'm watching in a 1080p TV, so it is bound to use all of the needed bandwidth.
Another concern is lag, because I game. Indeed, my home wifi is not 1ms-stable, but it is in the mid-20s, so are the gaming services I use, WHILE someone is watching Netflix. with a dsl line to the fiber on the street, 40mpbs on speedtest.net being frequent, and 30mbps being the minimum.
I highly doubt they will ever release 5G on unlimited load plans like my cabled connections, but instead use the 4G model.
So, yeah, it may be great, low latency, great bandwidth, but they will charge through the nose anyway to get an antenna somewhere on the top of the building (mine does not allow individual ones) and then again, cable the whole thing through inside the building and then AGAIN using my home 802.11 AC wifi to provide the last mile... not practical.
Either it comes through the wall with great penetration directly to my stuff, or not at all. Even if it does, what about the rest of the stuff? Everything else uses wifi, would they provide 5G adapters to EVERYTHING? Would I have a 5G receiver in the most innard portion of the house to pipe it on my wifi? Nobody thought this through...?
TLDR won't work for me.
