What band does an Xbox1 support

Hi Minette. My name is Kyle and I'm an independent advisor.

The Xbox One supports Dual band 2.4GHz and 5GHz spectrums. More information on Xbox One specs can be found here: https://news.xbox.com/wp-content/uploads/sites/2/Xbox_One_Spec_Sheet.pdf

Thanks,
Kyle

The 360 S only supports single band. There is nothing to stop you using the 360 N wireless adapter accessory on the new S model though.

Hi, the internal adapter supports b/g/n at 2.4Ghz, no 5Ghz no A

Ok, thank you for the replies. Thats good to know, had my console finally died *knocks on wood* and been beyond self-repair, I would have originally sold my Wi-Fi adapter knowing that the S models had built in wi-fi.
Now that I know the built in wi-fi is single band, I'll keep my adapter in that scenario. It doesn't support N, but I'm not going to spend another $65 on amazon/newegg just for the faster N bandwith (54Mbps on A is more than enough for internet speeds). I
would have been frustrated had I bought an S to discover it is single band since of my wireless devices, only my Xbox supports the 5GHz band, otherwise my router would have been a waste of money.

It kind of makes sense to include only single band on built in wifi to keep the costs down (although it wouldn't cost but a few more bucks for the extra band). Hopefully the Nextbox supports dual band A/B/G/N built
in.

Does the xbox1 support 4k? I could of sworn I read something like that on the box it came in or the instructions or something?
