2020 iPhones May Support New Short Range Wi-Fi Standard

[I7guy]

Apple better take it easy with the tech in the 2020 phones, so there are some useful upgrades left for 2021.

802.11ay?

The Fonz approves.

Canadians also approve, eh.

5GNR in the mmWave spectrum has no common elements with 802.11ad/ay. not even at the PHY layer. it requires a different baseband and a different RF stage. IMO 5G mmWave is useless as it suffers from the same things as the mmWave in the v-band.

Not useless, just unknown uses. We have been using 60GHz to transmit 4k uncompressed video for several years. About 30ft or so. NO LATENCY, .0004 seconds is what we have estimated. Very secure medium to connect on. No interference from traditional wifi traffic.

well, no interference from wifi, sure, but a lot interference from the same band. unless you use beam-forming - which most probably you can't due to LoS issues - you are stuck with this ultra short range reach. there is indeed some latency due to packetisation, indeed it is pretty fast between the AP and the station. and the same thing can also be told from modern wi-fi, especially wifi6. i've been using 60ghz in outdoor scenarios in the last 4 years, ad and pre-ay. you can do cool stuff, sure. but it's hard to imagine any suitable mass-market use case that cannot be served using wifi6/6e, which has far superior propagation properties, doesn't suffer from extreme free-space path loss and can essentially work with little bent wires as antennas, whereas for 60ghz you need phased array antennas and a dedicated DSP to get them working. don't get me wrong, 60ghz is awesome, but it's properties make it more useable for fixed operation. still, there's a tons of research going into this, but to solve traditional challenges. 60gig isn't new, it's there since 2010 and as you said, the major use case was high/ultrahigh res video streaming to vr headsets. seems we haven't got much further in the consumer area. whereas the current practical applications of the free mmWave spectrum center around short-mid range high speed communication between multiple fixed equipments, like bridging the gap between nearby houses, etc. there are amazing products available commercially, which can break the 1-4km distance limit with 60ghz, but none of them is by any means compatible with handheld devices.
