I can't tell if "thr" is a typo of "the" or an abbreviation of "their".

lol typo of "the." I hate typing on mobile.

This seems like the perfect type of error which is caught by autocorrect. Do you have it enabled?

What I’d love to see is my Mac be able to connect my Zoom or Teams meetings to my AirPods via my iPhone (on wifi) so that I can freely run to the kitchen without losing Bluetooth connection.

Tangential, but I am amazed by the Bluetooth range I get out of my AirPod pro and iPhone 12. What the hell are they doing? My laptop doesn’t even get to 1/4 of the range. I’ve walked into a vault (like a bank vault) with my phone outside of it, and the music never stopped. I’ve walked a good 20ft and everything was still smooth.

What other quality Bluetooth devices do you have or have you used? While Airpods and iPhones work excellently (I have both the gen2 Airpods and iPhone 12 mini), my Sony XM4s also have great range with my Windows desktop.

A recent development not mentioned in this article is Wi-Fi Halow/802.11ah, this is a new standard using the 900MHz ISM band. Advantages of this are better signal penetration/range for the same output power (or lower output power for the same range).

Compared to 2.4/5G wifi Halow uses narrower bandwidths so has lower data rates but is still much higher than BLE. BLE can do up to ~2MBit with a 2MHz BW, 802.11ah can do up to ~8MBit with a 2MHz BW but can go up to 16MHz BW. Additionally 802.11ah supports MIMO, so it can also scale the bandwidth up with more antennas.

There are some other new fun features in 802.11ah namely TWT (target wake time) which is a powersaving method that solves a lot of the problems the article mentioned with powersaving in wifi.

Slightly off-topic: Caring about slight latency differences but then still using joysticks for a shooter seems rather weird.

And yet when the military wants to shoot for real, it uses joysticks and not keyboards.

Huh? Who suggested that keyboards are better than joysticks for aiming?

For aiming in a shooter you have: keyboard For the military applications, the inertia of the thing you are aiming is important. In the most concrete example, think of swinging a rifle around to aim it. For a slightly more abstract think of aiming artillery.

I’m comparing the same AirPods between iPhone and my Thinkpad and I can’t get the same range. Unfortunately the only other Bluetooth device I have is my aftermarket ECU in my Miata and there is no iPhone app to connect to that one.

There's been extensive study into the latency difference between 360 controllers and ps3 controllers. There is virtually none and it's definitely not noticeable with all the other latency sources in the signal chain. Edit: one public, easy to digest source https://www.reddit.com/r/RocketLeague/comments/8wvf9u/contro...

That's on a PC. I'm not saying console results aren't similar but they aren't necessarily the same. Regardless, it was the common perception at the time and thus affected the behavior of players.

You might be surprised to discover that the radio waves don't care if they're going to a desktop PC in a traditional case, or a slightly different desktop PC in a Microsoft/Sony case!

It was not "the common perception". At best it was common among your peer group?
