5G isn't just millimeter wave. Over the next few years, the majority of 5G will be on the 2496 to 2690 MHz (T-Mobile on recycled Sprint spectrum) and 3450 to 3980 MHz (AT&T, Dish and Verizon on 3.45 GHz, CBRS and C-band) bands.

Of course it will be because of the above mentioned problems. There is no way they'll be able to put up that many antennas any time soon, it will be a slow process. Those frequencies you cite are about the same as current 4G, with only the latter being slightly but not significantly higher. It's part of the reason people who try 5G end up disappointed it's not as fast as they expected.

The question is who is this actually a good deal for? Do consumers understand they're going to pay those hundreds of billions? Do they understand 5G means having antennas all over the place? And do they understand the privacy concerns? Most in my experience do not. I also find it interesting that right from the start there was a ton of noise in the news about "conspiracy theorists" fearing 5G for ridiculous nonsense reasons. Just the sort of thing you'd expect from a black propaganda campaign. But there was few talk about the actual tech, no talk about who decides these standards and why the entire world is supposed to sign up.

Do people know for example a Huawei guy is chairing the group that's bringing us wlan sensing with a noval 802.11bf wifi standard as well? So the milimeter scanners will be in our homes and outdoors as well. In my experience almost no one outside of niche tech bubbles knows anything about this. They just know faster internet good, they have no idea about the politics behind all this.

It's worth pointing out that 5G is just a protocol which can, in principle, be operated on any of the frequency bands currently used for LTE. For instance, T-Mobile is currently providing 5G and LTE concurrently on their 600 MHz band.

> because 5G uses a totally different wavelength than the 4G standard your phone currently uses. The 5G standard uses millimeter waves, which are a lot shorter than the wavelengths 4G uses.

That article is just wrong there. Yes, 5G adds additional frequency bands, but no, those do not need to be used for 5G, and it also uses the same ones as LTE does. Which your usual 5G upgrade does.

I use 5G in lieu of fibre. I live about a half mile from the tower and I get 200Mbps consistently. Connections rarely drop, I am ssh’d into cloud machines for hours without issue. All this for £25pm and maybe £350 for the SIM unlocked 5G router. UK based.

Is this unmetered or you stay w/in the cap?

Unmetered

Not sure the 1000ft statement is accurate. I have 5G ISP and am ~4200 feet away and it works great: http://ewams.net/?date=2022/01/11&view=TMobile_5g_Internet_F...

That's because you're not on those frequencies, see the other comments. 4G(+) works great, sure. You're not downloading 20 Gbps, are you?

5G spectrum is not limited to high frequencies.

5G spectrum goes from high-bands 24-40 Ghz, mid-bands 1-6Ghz, and low bands < 1 Ghz

But aren't those hz bands limited in their throughput to about where 4g is?

increased synchronization between stations should allow for better beamforming to go along with the positional information, increasing throughput somewhat in the face of interference/attenuation

IIRC there is also a lot of improvement in channel multiplexing both at raw physical layer and link layers to allow e.g. numerous IoT type devices to have a low-rate cell connection without a plan.

This also allows packets to start at more times, which means that latency can decrease. (aka, lower ping times.)

Ah so a more robust and reliable, multi station system is formed? What's this beam forming and positional information stuff? Are they tailoring signals to individaul devices? That's so cool! This stuff is starting to feel like electro magnetic magic, haha.

yeah- they call it time-domain-multiplex (or something) when you have different phones subscribing to listen at different points in time. Traditionally only the closest station would broadcast to each phone, because multiple stations broadcasting the same frequency leads to a mushy signal (on average). BUT, if all the stations are synced, they can align the phases of their signals so that they 'constructively interfere' into a brighter signal where the target phone is. The appropriate phase difference will be different for each phone, so each time slice signal is indeed tailored to each device-- they also need to track device movement, to best target the signal while it drives/walks around.

'beamforming' is a kind of confusing term, based on how a bunch of antennas in a tight group can time their phases into a cone of signal-- functionally aiming the antenna, but without anything physically moving. When the involved antennas are not in a tight group, the 'beam' that is formed starts to look less like a cone, and more like a target 'bean'... beanforming ....

anyway this demo page can show some of how it works, ui is kind of weird, type a number and click to add/move an antenna, hit 'r' and click to place the receiving device, 'o' to align the phases for best signal.. https://apenwarr.ca/beamlab/
