Wifi and bluetooth interfering - some curious questions

[burnedsandwich]

Hi,
I am using a Xperia X and experienced some problems with Wifi and bluetooth interferience in some cases.
With my old Headphones (logitech ue 9000) it is a real pain. If I try to use them while streaming something via wifi the audio is very often broken off.
If I use these headphones with another device (e.g. my ps vita) they work flawlessly. With a bluetooth speaker I purchased recently, I have less problems using my xperia x, the brake offs appear only rarely.

I read that wifi and bluetooth use the same frequencies, so I guess it can be expected that they interfere with one another.

I was just curious why this seems to be device specific.

Do other devices and OSes have techniques to avoid these interferences and ubuntu touch does not?
Has this been adressed with recent bluetooth versions and this is why I have the troubles with my old headphones?

Is it maybe possible to avoid this by just forcing my phone to use 5 GHz instead of 2.4 GHz? I think then it should not interfere with bluetooth. But I do not know how to do that.

This not really a bug I think. I am just interested in what my device does here.
I am happy for any reply.

Hi @burnedsandwich

Bluetooth is unreliable on Ubuntu Touch, your experience may vary depending on the device you are using.

Yes indeed, BT and Wifi use the same frequency but there shouldn't be any significant impact.
I guess such interference is handled at hardware level, fine tuning the antennas and such...

AFAIK forcing, or even using 5GHz wifi is not a thing in Ubuntu Touch, so this won't be a solution.

Maybe you can force wifi 5G on your wifi box ?

@applee My Virgin router has separate networks for 2.4GHz and 5GHz. I just set up the 2.4 witth a lowercase name (ssid) and the 5 with the same name in upercase. Just select from your wifi drop down on UT. 5GHz has more bandwidth

Thanks for the replies.
Right now my phone doesn't want to connect with the 5 GHz network. But I thought I had seen that device using 5 GHz already. strange.
