As I’ve learned more and more about 5G (which is a nebulous term, really, but what I mean specifically is the planned upcoming releases of LTE 16 and 17, as well as the features of LTE 14 and 15 that users have yet to take advantage of) I’ve become convinced that it’s going to transform how so much of the world is designed. 5G technologies allow for more devices to send more data using less power. This is achieved us…

> As I’ve learned more and more about 5G Out of curiousity, what's a good source of information on 5G? I assume the standard itself is not the easiest thing to digest so I'd appreciate your input.

An Introduction to LTE by Christopher Cox and sharetechnote.com have been most useful to me

Reading through this, it doesn't sound like the people involved considered the amount of outright misuse some of these features are likely to enable. Haven't we already seen bad actors will misuse mobile tech to track our movements, spy on people, (etc) on a wholesale scale? This seems to be wilfully charging down the road of making it worse?

I bet that the concerns of the average user are not really what 5G committee members thought was most important.

Fair point. :)

Unfortunately though, they really should.

5G doesnt seem like its enabling anything fundamentally new. The talk of any ”killer app” based on having more throughput or on these optimizations always feels like demand generation and slightly inauthentic. Are there any technologies enabled by these techniques that are not possible today?

Last mile for fixed rural wireless broadband seems like the obvious one. Today, this is generally done with either LTE or various proprietary things (or if you’re particularly unlucky, satellite). 5G should allow for greater total bandwidth, reducing the impact of contention. And on the other side, it should be helpful for very dense urban usage. Try using LTE in a large city’s central train station at a busy time an…

I don’t really see 5G solving rural broadband issues. You still need to lay backhaul line from the node Bs, and 5G requires more of them, so it’s not orders of magnitude cheaper than running cable to home.

Uhh, I'm not sure what that was but I tried to access that site via Tor and on the particular exit node I was on I got back a "418 I'm a teapot" response. Yeah, it got weird.

I haven't researched it fully but to me it seemed like a utopia.. For the device makers, and dystopia for the customer.

Imagine all your wireless IoT except you can't block them or filter from the wifi network, they are always connected and you can't see what data they're sending.

The idea of vehicle to vehicle communication is a bit frightening. Imagine the obscenities and insults you yell at other drivers, are now able to be communicated directly to the object of ire.

We had that back in the 70's. It was called Citizen's Band radio.

Beamforming and generally avoiding omnidirectional signal is something that's been around since at least HSDPA, iirc? At least that's when I heard of it in telco...

It’s true that beamforming itself is not new (there’s actually been rudimentary beamforming since 2G). But beams are getting small and targeted enough to support space division multiple access (same frequency can be used for many mobile stations in different locations). Also, 5G mobile stations themselves support beamforming, which is important for uplink bandwidth and power usage.

One thing the Test and Measurement industry is looking forward to, is being able to have extremely high bandwidth (wireless) connections between gear.

The idea is that with 5G you can combine your function generate with your oscilloscope to form a basic network analyser with the data travelling wireless between themselves and your computer. The throughput is high enough, and there wouldn't be any wires.

Don't buy them then? It's not like you can control most IoT today
