I translate this as “Qualcomm admits Bluetooth is a shitty mistake and its time to move on”

Bluetooth still has its place in several instances. From what I can tell, this wifi protocol depends on you having a WiFi network mediate the connection, such as at your house or at a Cafe. Bluetooth is true ad hoc requiring no middleman.

Bluetooth struggles with bandwidth enough that it affects sound quality and latency, but that doesn’t mean it’s unusable. It also has enough range that I beats some other competing wireless protocols as well.

I’d love to see WiFi or a higher bandwidth option come out, and I’m hoping this is the beginning of that. They may have to resolve issues with channel conflicts and the need for network mediation. It would be awesome for gaming.

Currently, there are some alternatives, or bluetooth versions which work pretty well.

Often wireless gaming brands offer a usb dongle. That dongle often uses a proprietary protocol over 2.4ghz. And allow enough bandwidth for audio and mic. Some brand give more or less bandwidth to the mic, or have better compression, or bandwidth.

And currently, there is a fairly “new”, already here since bt 5.3 : LC3. It’s a very well optimised protocol which allows for about the same quality at lower bandwidth than other protocol. It also has lower latency. This protocol has started to be used by gaming brands, like Creative, in a usb dongle. Or even in standalone headphones. On the Creative headset, it would allow enough bandwidth for audio and mic without much compromise (like if it wad a proprietary dongle).

Obviously the quality may not be as good as wired. But it should be enough for most people.

Huawei also seems to have announced (not sure if yet released, it should be in an honor phone), their bluetooth competitor. They say 6x faster (more bandwidth I guess) https://newatlas.com/mobile-technology/nearlink-wireless-huawei/.

I think the earpieces act as a Wi-fi hotspot themselves

Bluetooth is awesome for many things still. And it keeps getting better. Just not better enough to be optimal for high quality audio

It should be read as “Qualcomm looking for new ways to put users on their proprietary IP so they can extract new profits.”

That’s a solved problem. You use an app for setup, like so many other screenless devices.

Hopefully once it’s common enough a standard process arrives. Actually I don’t think this will take off without that, else we will need an app for iOS, android, windows, Mac, Linux, several tv OS…

It can also start an adhoc network that you join on your phone, and input the wifi details via the browser, although this is more complicated for the device itself. Lots of low spec/low power devices do that though.

It’s addressed in the article. It’ll just share the credentials from your phone.

That’s unfortunate. Devices like that are basically impossible to use on certain enterprise networks (e.g. college campuses). There really needs to be an override

it would be a dedicated network between your phone and the earbuds based on how I understand

I’m personally more worried about SECURING the network between my headphones and my phones …

Yet another vector of attack … let’s hope they use a modern encryption standard and that they update in a timely manner when a 0D on the protocol is found

but it’s Qualcomm, it will be fine, right? right? … guys? Right?

24 bit / 96kHz playback over WiFi is going to be huge.

Whats the point of 96kHz(playback)? You basically only produce sounds outside of the human hearing with that.

absolutely nothing outside of the recording studio. It’s useful when handling intermediate s when you’re mixing several recordings. Once the mix is done, it’s useless

No point really. The Nyquist sampling theorem says that 44.1kHz is overkill, much less 48kHz or anything beyond. You only need twice the sample rate of the highest frequency to be reproduced, and human hearing generally goes up to 20kHz (less for almost all adults). Accordingly, many production recording equipment won’t even bother with frequencies approaching 20kHz. The only conceivable point is that you don’t need to resample files in higher sample rates, which saves you a tiny bit of cpu time I guess.

Dynamic processors (e.g. compressors, limiters, peak detectiors) are more accurate at higher sample rates (and bit depth). Also, less latency at higher frequency. Lastly, it greatly improves editing including “modern” processing such as time streching, pitch correction etc. I am not sure what the effects on “spatialization” are …

This is why I put playback in brackets, where it makes no difference at all. On DAC’s it can be useful, because you can use them for other stuff, but in headphones and IEM’s its completely useless.

I thought that too. However last I checked Wifi Direct still loses to Bluetooth LE in idle power consumption.

I do hope wifi direct or UWB can catch up so we can finally sunset Bluetooth.
