The first article feels confused, as if the author copy-pasted from various press releases without understanding the topic. OFDM is not new at all for example.
The PPT is from 2015, when 5G was still just a bunch of ideas.
I've heard serious concerns about lack of safety testing and regulatory oversight. The problem is that it's difficult to find credible sources pro / con. Would be interested in reading if you have any to share.
From the first link: "Comparing OFDM to LTE today we find a better scalability to a much lower latency (an order of magnitude lower round-trip time [RTT] than LTE today) in OFDM."
Doesn't LTE already have quite good latency properties?
If you know of an article that sums up what this standard protocol does, how it does it, and why that wasn't possible until now, then could you please post a link?
Maybe someone could help me with a LTE issue here...
I'm in Croatia, about 1km from the tower, -70 dBm.
The (ZTE MF286) router has a MTU 1500 and MSS 1300 setting.
I can change this setting.
In Germany I have a VDSL (Telekom DSL) 100/40 MBit/s home network.
A Fritz!Box 7590 is on the front and it's providing VPN access over old age cisco type xauth1+psk (aka user pass and group pass).
When I try to connect in Archlinux using Networkmanager-vpnc I can connect to the German home network.
But I can't ssh into any boxes in the German network.
I am able to do that over Croatian DSL without issues.
The adapter's MTU is 1500 and the tun0 MTU is 1412.
So this works over DSL but not over TLE.
When I change the adapter's MTU down to 1420 (reading libreswan's site I stumbled upon this value) I can login via ssh and seemingly also use it as it's supposed to.
But then other issues arise...
TLS Handshakes timing out. As if a dog is trying to chase its tail.
I've canceled the TLE service subscription in the 14 day period because of that and I'm going to return the router today in 4 hours tops.
This this is kind of a last straw kind of help request.
Otherwise I'm stuck on a 14/1 Mbit/s VDSL connection which is painful to say the least, but at least I'm able to ssh into my German home network without problems.

Another somewhat high-level PPT http://www.5gsummit.org/docs/slides/John-Smee-5GSummit-Silic...
I've worked on LTE; the 5G NR physical layer look to me to be very similar to LTE. See http://www.3gpp.org/DynaReport/38-series.htm and https://www.keysight.com/upload/cmc_upload/All/Understanding... for gory details

If not, what must happen in order to allow everyone use Netflix on their phones without wifi?
