2020 iPhones May Support New Short Range Wi-Fi Standard

We are, this isn't actually a Wi-Fi generation. Wi-Fi uses either 2.4 GHz or 5 GHz.
This is talking about a new communication standard that uses the same communication methods and hardware as WiFi but at a higher frequency (60 GHz) with almost no wall penetration and range. So it'd be ultra short range (same room) but super high speed.
If I'm being uncreative, I can imagine this as an NFC replacement or a faster/better AirDrop.
I can also imagine it being really useful for wireless streaming video- like wireless monitors, AirPlay-without-being-on-the-same-wifi-network, or VR/AR glasses with no wires.
in the v-band the channels are 2GHz wide, and there are 6 of them that don't overlap. it uses a really simple modulation and even with 802.11ad it has 4.6Gbps on a single channel. no MIMO, no channel bonding, nothing. with 802.11ay there are alternate PHY modes that rely on synchronisation and offer TDD media access (not just the regular CSMA-CA), but it also introduces MIMO and channel bonding. a single 2GHz channel at full MCS should be able to provide 18Gbps bandwidth. another thing is the propagation properties in the v-band: they suck. 60GHz is attenuated by O2 in a dramatic way (90%+ RF energy is absorbed) - so without beamforming and beamsteering it will not get far. but this also introduces a big benefit on the frequency reusability side and potentially eliminate interference in "regular wifi distances". indeed i see it to be quite problematic to use as any of your body parts can easily block it.
I'm picturing wireless displays. It's 60 GHz so there's no wall penetration, you'll have to be in the same room, but it'll have way more bandwidth and little interference from other signals, so it'd be really really effective for that.
Antenna. For Qualcomm they are already part of the whole package with X55+ their WiFI solution, whether you want 802.11ay or not. Not sure how Apple is going about this since they dont use Qualcomm's WiFI Solution, RF From End, and rumours has it they dont want the mmWave antenna modules either.
The engineers use the terms 802.11ax and similar.
802 means LAN standards, .11 means WiFi standards using a particular way to handle sharing the channel.
The successive standards were a, b, .. up to z at which point you move to 802.11aa, ab and so on.
Note that WiFi exists no-one in the above description. The engineers put the specs together. Then marketing/product people get together to decide which aspects of the spec will go into "most" consumer equipment. That subset is decided by the WiFi alliance, and they do things like branding, interop tests and so on. You CAN sell an 802.11 device without submitting it to testing by the WiFi alliance, but you can only call it 802.11, you can't call it WiFi.
SO if you want a WiFi type name, look at what the WiFi Alliance are doing.
They used the term WiGig to refer to 802.11ad, an earlier version of the 802.ay spec.
My guess is they will probably stick with WiGig. So few people ever bought the earlier 802.11ad stuff (and they were all tech savvy) that there's little risk of confusion.
And why WiGig, not WiFi60 or whatever? Because it is different technology with different expected use cases and tradeoffs, the same way we don't call Bluetooth WiFi-B or whatever.

Read about it:
IEEE 802.11ay - Wikipedia
Bottom line is that this is NOT just a variant on existing 2.4/5/6GHz WiFi; it's a very different frequency band. I would guess that the MAC is also very different (god I hope so; we're still suffering with sub-optimal decisions made for the original 802.11 MAC protocol) but I don't know details at that level.

it is all there. the WiGig alliance had several extensions, incl. Wireless DisplayPort with HDCP2.0, back in the early 2010s. there was also some serial extension, mainly aiming for wireless USB. and a bunch of A/V solutions as well, some with support for uncompressed HD video.
today you can just do most of it over IP/IPv6 w/o special adaptation layers, based on 802.11ad-2012.
They are unrelated. 802.11ad and 802.11ay are intended for a completely different use-case, and as such, are not being marketed in the same way as Wi-Fi. 802.11ad is what you may have heard of as "WiGig", a short-range but very high-speed tech, requiring nearly line-of-sight between the two devices. I'm not sure what the marketing people will call 802.11ay, but perhaps WiGig2? Haven't heard about it until now.
Surprised nobody is mentioning this standard as likely pushing Apple toward port-less iPhones and iPads. It’ll likely take a few more generations, but seems like they’re serious about getting rid of ports.
Oh, Apple...
Oh, Apple...
It's not IP. IP just costs you 48 bytes every 1452. (Compare to DisplayPort which has packets that costs about 1.5%)
It's the video compression, H.264 or similar, that causes latency. A uncompressed 1080p60 stream needs 3.2 Gbps and 4Kp60 needs 16 Gbps. Existing solutions, like Airplay and Miracast, compress that down to 10-30 Mbps.
The idea of WiGig and wireless HDMI solutions (WirelessHD, UltraGig) is to provide so much raw bandwidth, you can use no or very simple video compression, like VESA DSC, reducing latency.

Yes, let's hope the AR glasses will use it.
It would be cool to view a screen and keyboard through the glasses. An AR keyboard could show-up in the glasses on a flat surface in front of the user with the keys working for typing.

I'm confused. So in future, phones will be transmitting/receiving ...
1) GSM/LTE
2) Bluetooth
3) WiFi
4) NFC
5) Short-range "WiFi".
Is that right?

5) should be integrated in 3) because we already got 2,4 GHz and 5 GHz WiFi. Nothing else, just another frequency.
current .11ad solutions support up to 9k jumbo frame sizes. for raw streams it makes sense to go w/o IP. but for encoded ones the latency increase caused by packetisation and IP is negligible compared to the radio delay.
You are conflating different things, I think.
802.11ad has 2.16GHz bandwidth.
802.11ay allows you to bond four 802.11ad channels together, which is how the bandwidth increases (not by shorter wavelength).
Additionally, there can be four MIMO streams (that "four" is different than the "four" channels). So the link rate for one stream is 44Gbit/s, and for four streams that makes up to 176GBit/s.
Yep. Thats my guess too. Especially now with the European Union wanting to force Apple on the connectors, this would essentially leap frog that. She short distance is not an issue if you are basically using it to transfer data data between two devices as with a usb-c cable.
I am thinking of getting this router below to replace my 8 year old one, anyone know please if it will be a good choice for the future proof for the iphone 12 , thanks.

Nighthawks are ugly, BIG, and feel fragile (those "wings" that are antennas feel like they are about to fall off).I am thinking of getting this router below to replace my 8 year old one, anyone know please if it will be a good choice for the future proof for the iphone 12 , thanks.

And the app kinda sucks, feel oppressive.
The HW specs are good (the USB and the multi-gig ethernet) but if you buy Apple bcs you want polished HW and SW you'll be very unhappy.
Right now the company that IMHO feels closest to the Apple experience (if that's what you want -- attractive HW+SW, does the standard stuff well and doesn't pretend to be everything to everyone) is Amplifi.
The Amplifi Alien is their WiFi6 box.
Thank you for the feedback , will do some research as i always used Netgear since 2000 before the ratification of the 802.11a ,with no issues even my current netgear 6200 V2 is a rock solid router but with over 20 clients at home it feel bogged down a bit beside it is way outdated, for sure will look at

Coverage in the house in the very good, features are good with no complaints about speed, either wired or wireless.
There is no such thing as a future-proof router or phone, imo.
