What kind of WiFi 7? (There are a lot that don't have 6GHz support).
You should get far better performance on 6GHz, though there are harsh power limits in most countries with various ways to enable it which may complicate things. But if you can get full power on 6GHz it should reach 10m no issues at all, and with 320MHz should be at least twice as fast.
If you can also get MLO working (which is not simple) you'd be able to bond another band with it.
- snovv_crash 1mo agoThe brick wall will prevent any and all 6GHz penetration.
- martinald 1mo agoNot at higher power output, which that router doesn't support.
- mort96 1mo agoWhy would 6GHz make such a difference compared to 5GHz?
- martinald 1mo agoBecause it supports (on WiFi 7) 320MHz channels. So there is double the bandwidth. 5GHz only supports 160MHz channels.
- mort96 1mo agoWouldn't it make more sense then to ask about high bandwidth channel support rather than frequency support? It's not the frequency that's important here.
- dragontamer 1mo agoHigher frequencies support higher bandwidths though. I don't think the 2.4GHz band even has 160MHz free, for example. Literally impossible to support because 2.4GHz to 2.5GHz is all you get (100MHz or so). 5GHz isn't much larger than 160MHz. Like it can fit but some number of channels is better for everyone. 6GHz band is like 5.9GHz to 7GHz or something stupidly wide. Because of the new wider band, you can effectively have larger channels with fewer problems.
- martinald 1mo agoYes exactly. Also with MLO (bonding eg 5GHz and 6GHz) together on WiFi 7 you could get 480MHz of spectrum, which would allow many gigabits quite "easily". Only problem is firmware support etc is somewhere between non existent and very poor in general for MLO, which is a shame as it's definitely a great feature in theory.
- mort96 1mo agoWell you can run any bandwidth at any frequency, I get that the WiFi specs define set bands which include both a center frequency and a bandwidth but it's a bit weird then to focus on the frequency when the bandwidth is what matters isn't it? I assume there are products which can operate on frequencies around 6GHz but which don't support the extreme wide band channels?
- dragontamer 1mo agoFocus??? These bands have names. The 2.4 to 2.5 GHz band (100MHz bandwidth) is named the 2.4 GHz band. The 5.4 to 5.7 GHz band is called the 5GHz band. The 5.9 to 7GHz band is called the 6GHz band. Anyone discussing the bands should know the relative bandwidths of each. And the size of the channels also matters but we all know the 6GHz band has larger channel widths, it's part of the point of upgrading
- bjackman 1mo agoIt's a Unifi Dream Router 7. The 6GHz doesn't reach through the wall IIRC
- martinald 1mo agoThat doesn't support high power 6GHz (called standard power/AFC). You need one that does support that to get the (much) higher 6GHz transmit power.
- utrack 1mo agoEvery once in a while I visit this page to see if there is any router that does support true MLO: https://www.rtings.com/router/learn/research/wifi-7-mlo#the-reality-what-current-wi-fi-7-routers-actually-do https://www.rtings.com/router/learn/research/wifi-7-mlo#the-...
- zipy124 1mo agoI feel like this is the same problem USB and bluetooth have, where there are so many optional extras, that it's so hard to truly compare devices since a standard is actually like 100 standards packaged together.
