Interesting study... I found this to be really surprising:

"In a web browsing test, 5G only reduced page loading times (PLT) by about 5% compared to 4G. This is because most of the time goes into rendering, i.e., is compute-bound. Even if we just compare download times, 5G only shows a 20.68% improvement over 4G."

Isn't the design intent of the 5G methodology more about maintaing useful throughout to individual devices in the presence of an increasing number of other devices (and other interference), than it is about massive throughput to single devices, in preparation for a predicted explosion of wireless IoT variable things? If so, then this result isn't a problem, we've just been primed to expect more by headline grabbing numbers coming out of artificial benchmarking experiments, that were never expected to be reproduced in the messy real world.

Awesome. I'm sure there are many applications that will benefit. And yet as a consumer / Joe Public I already get that from WiFi. When I'm not connected to WiFi (which is not often), 4G is more than adequate. The only thing I see 5G doing is increasing the tracking resolution for my whereabouts. Nobody ever tells me what my Telco is doing with THAT that data.

5g operates at 3.5ghz carrier freq with 100mhz channel b/w. due to higher frequencies channel quality suffers from degradation indoors, and higher attenuation as well. this in turn will require higher density of gnb deployment to prevent coverage holes...

for now.

5G NR frequency bands covers also the same frequency ranges as 4G/LTE not just the new high frequency channels.

Some carriers are already using low-band spectrum (600 MHz) and mid-bands.

It's about as surprising as the fact that sending e-mail, streaming video, playing online games and even browsing the web doesn't turn into a "Richer(tm) Experience(r)" when moving from a 30 mbit/s wired connection to a 100 mbit/s wired connection. 5G, just like 4G, will help with enabling more bandwidth availability and lower latencies for increasingly larger groups of clients to share, but as an individual user on a node that isn't over-encumbered there won't be any exciting differences to take note of compared to 4G - and in many cases, not even when compared to 3G.

Yeah but you don't get the gigabit numbers that way. That's all marketing wants.
