These days with 4G i do find that it is not the technology that is the bottleneck. It is the carierers trying to hold on to their business model. I would prefer if we aimed our research on increasing coverage.

The technology is still a bottleneck, but the business model just isn't tightly fitted to the limitations of the bottle neck. 4G cannot viably stream 1080p netflix into the number of homes in America that use it at any given time (unless you use an unrealistic number of cell sites). Some sort of rationing has to occur otherwise cells would be overrun. Carriers should bring back free nights and weekends.

4G has been my only connection at home since 2013. I pay 20 euros a month for unlimited 50Mbit/s 4G connection and I can watch two Netflix 1080p streams and do other things at the same time easily. ISP also provides public IPv4 address so I can run servers at home. I live in Finland.

No end-to-end encryption though. Oh well, maybe for 6G?

Even 4G (LTE) is typically end to end encrypted. Unsure what you are trying to say or if you're just trolling.

End-to-end encryption typically refers to "one user to another". Not from "one base station to another" or from "one carrier to another".

It should've been quite obvious in the context of privacy.

I'm really interested in the potential for p2p networking in 5G. But I've been disappointed that LTE Direct[1] hasn't really become a normal thing since a couple years ago when Qualcomm announced it. A cursory googling of 5G shows that some amount of 5G research has focused around device-to-device, mostly for IoT purposes[2][3]. Link [3] in particular talks about the challenge of incentivizes:

> Besides the technical challenges, there is the very practical problem of incentivizing users to lend their devices to serve as relays for the traffic of others, especially since these connections will consume bandwidth, storage, and battery power on the relay. Again, the appropriate class of solutions depends upon the D2D design.

If this D2D does become a central part of 5G, I'm really curious about whether users will be able to use 5G not (only) with a carrier's towers, but as a part of a mesh network (and as a Bluetooth- or wifi-like tool for local networking). It could be a great way to chip away at the power of carriers and ISPs (which might be one reason LTE Direct is nowhere to be seen, and why D2D 5G capabilities could be gimped in end-user devices).

I'm a complete layman in this area, so I'm curious to hear others' thoughts.

Free nights and weekends is exactly anti-net-neutrality. I have always been an advocate for more, open, spectrum, and simple laws to outlaw intentional interference. We are not operating dumb radios - we can dynamically change or allocate spectrum channels to load balance congestion and avoid making it worse. To legally cordon off everyone into separate silos is a hatchet solution to a nuanced problem with much bette…

The Shannon-Hartley theorem is a harsh master. You cannot squeeze more then bandwidth times log 1+S/N through a radio link. You cannot have antenna gain beyond the diffraction limit. Power amplifiers have limited bandwidth.

I use an LTE hotspot as my main access point in Belize, but I have to pay $5/GB for it. :( Edit: My hotspot tends to run at around 22Mb/sec, which is faster than the fastest DSL line you can get here, which is 16Mb and costs $400/mo.

My AT&T plan in the US is $6.66/GB for the first 30 and $15/GB after that. Just tested, I'm getting around 27Mb/s down.

This sounds about right sadly. It will be interesting to see how the carriers market these better speeds and latencies if it doesn't also include better affordability.

you're funny.

This is great. If only we could get true 4G in the US...

When I went to the US two years ago I got LTE in the Baltimire, Washington DC and Los Angeles areas so you guys do have true 4G. The issue is more the amount of LTE coverage avaliable which isn't that great outside of the main cities (or at least it wasn't at the time I visited).

The rising capacity will be offset by rising average page size. What the network giveth, the browser taketh away.

Its just like building highways to alleviate traffic.

Bandwidth caps exist to destroy demand, and they do the job well (no different then London's congestion charge).
