We need reliable, real-world ~20mbit/s for our warehouse scanners, not 382722 theoretical Gbit/s 5cm from the access point. And roaming that works instead of stupid clients clinging to somewhere or being thrown into a reconnect loop when the AP tries to get them to roam. I know this is theoretically possible today. But in the real world, I have inherited the setup, so AP locations are fixed for now, clients are some…
Having WiFi 8 (or even 7) on your access point is only really useful if you have a population of clients that can use the features it offers. I regularly sample the devices attached to residential wifi routers and the facts are grim: in a house of 40+ devices, two can do wifi 7, about 10% can do 6Ghz, 50 to 60% can do 5GHz but not 6GHz, and a core rump of 50% of the devices are stuck on 2.4GHz. I suspect this is beca…
For example, Wifi 7 doesn't make actually useful MLO mandatory. So most wifi router manufacturers - even Ubiquiti - don't implement it! What's the point of adding something to the standard if it's optional.
Ideally, the standards body should make expensive stuff mandatory- then prices will come down as soon as everyone is building it, due to economics of scale.

An additional radio would raise the price of your phone for at least another 200 or 300 dollars. Try to enable VoLTE if available for your operator. That makes the phone use the LTE connection for voice and don't drop the Internet connection while you talk.
You can get an additional phone with a screen, 5g radio, ram and everything for $150. An additional radio should not raise the price for another 300.
What about latency and jitter? I still get more ping in Counter-Strike on Wi-Fi than on Ethernet. …even in pristine conditions, excluding perfect lab conditions.
Wired switches have dedicated physical cables linking to each client and can buffer packets per-client, buffers that can be flushed at optimal times.
If you could guarantee that (1) you were the only client on the access point and (2) there was zero interference from any nearby access points, then I’d expect the latency/jitter to be comparable. But that’s basically impossible unless you’re inside a faraday cage with direct line of sight.
People who are experts in wireless, when they have the choice, will always pick wired communications where feasible, if latency and jitter matter.
It's the first because we finally caught up on speed. We have it better than I imagined possible. Last year, I saw 1600 Mbit/s from the Internet at a normie's place with an ISP-provided router. Still have a cat 6 cable around the living room but haven't used it in the last 2 years. Not exactly wifi but I routinely get 600-800 Mbit on 5g networks in crowded areas.
anybody tried fiber network / hubs at home ?
And I have cat5 in my walls that was installed 25 years ago (way before it was my house)... That gets me to 10g everywhere I tried, so no reason to pull anything else.
Dumb question: why not drop/deprecate the WiFi standards and adopt 5G/6G across the board (operating on different spectrum depending on configuration)? Naively, I would assume that would save money on the BOM and make devices more flexible. Again, naively, why not build and sell consumer-grade 5G access points/routers? This new WiFi standard is far enough out (2028) that it seems reasonable to fold it into the 6G sta…
I'm not talking about legal differences- laws can always be changed- but rather how bandwidth is allocated. The biggest benefits of cellular comes from:
Verizon owns/controls channel
↓
gNB decides:
"You transmit here."
"You transmit here."
"You get 20 MHz."
"You get these time slots."
Everybody shares unlicensed spectrum.
AP: "Is anyone transmitting?"
↓
wait
↓
transmit
Are we not yet at a point where we could have a truly global network that uses multiple technologies and mediums to keep a user always connected? Like seamlessly switching between Wi-Fi, nG, Bluetooth, satellite, pigeons, cans-and-wire.. and still having a stable global address? (that you could change later of course)
It's possible using overlay networks but other than that there has been no progress on that front. The routing table updates would overwhelm the system. Ipv6 does nothing to address device roaming. There is multipath TCP but I have never encountered anything using it. Most improvements on that front has been happening on the application layer, where the app attempts to retain functionality even though the underlying…
IIRC siri uses it and iOS (maybe macOS too?) exposes it to app developers.

Dead outside the US unfortunately, worse range than regular wifi due to being strangled by lower channel width and ridicolously low power limits. The two bulky HaLowLink routers are the only off the shelf thing with support for it, it's nonexistent as a wifi standard. I was so excited when I discovered it a few months back after struggling for years to set up reliable wifi for outdoor robotics, only to realize we can…
LoRa is not fast enough?
Seriously. Only rich nerds in SAN FRANCISCO are using it.
Ever since I found out that this is possible, it seemed like the obvious better choice because it divides the spectrum across everyone equally with no configuration, whereas on WiFi you (or your router) always had to choose one channel to work on and hope for the best. It might look clear for a full minute, but then the neighbor presses 'next song' 20 seconds later and whatever channel they're on is now trying to push some megabytes of audio. Probably it also has downsides or they'd long ago have done this, though?
Edit: https://en.wikipedia.org/wiki/Frequency-hopping_spread_spect... (used by Bluetooth) mentions also that some jurisdictions allow a 1000x higher transmit power if you hop between enough frequencies with short enough dwell times on each, which it sounds like Bluetooth would easily reach at its usual 1600 hops per second at the full 2.4 GHz unlicensed band

Why would 6GHz make such a difference compared to 5GHz?
Because it supports (on WiFi 7) 320MHz channels. So there is double the bandwidth. 5GHz only supports 160MHz channels.
