Why Wi-Fi 6E in Europe is a lot worse than within the US

WiFi channels in 6GHz

The brand new 6GHz band supplies a bandwidth of 1.2GHz, this new frequency band is obtainable from 5925MHz to 7125MHz, and inside this enormous frequency band is the place all units with the brand new Wi-Fi normal will join. Fi 6E, but additionally the units with the longer term Wi-Fi 7 that can arrive within the subsequent few years. Due to this fact, this new frequency band for Wi-Fi networks is essential, as a result of it’s the way forward for wi-fi connectivity in all our houses.

In Europe we solely have the UNII-5 band out there, which ranges from 5925MHz to 6425MHz, which means that we’ve 500MHz of bandwidth to attach the completely different units. On this frequency band we’ve a complete of 24 channels of 20MHz channel width, 12 channels of 40MHz channel width, 6 channels of 80MHz channel width and three channels of 160MHz channel width.

By default, the Wi-Fi 6E normal makes use of 160MHz of channel width, due to this fact, we are able to solely join a complete of three units to the Wi-Fi community on this frequency band, with out interference between them because of the closeness. Within the case of the longer term Wi-Fi 7 normal, we should keep in mind that we’ve a channel width of as much as 320MHz, so we are able to solely join a tool with this channel width, as quickly as there are two close by units we can have interference between them.

In the US they not solely have the UNII-5 band, however in addition they have the bands of UNII-6, UNII-7 and UNII-8. Which means that they will use the brand new frequency band from 6425MHz to 7125MHz, one thing that we can’t use in Europe, that’s, we’re left with out utilizing an extra 700MHz of bandwidth that they will use.

Within the following graph you’ll be able to see the out there channels that they’ve within the US and those who we’ve in Europe.

What does it imply that within the US they’ve extra bandwidth out there? They may have many extra channels out there, greater than double particularly, for instance, as an alternative of getting solely 3 channels of 160MHz channel width, they are going to have a complete of seven, an enormous distinction. As well as, with the longer term Wi-Fi 7 they are going to have a complete of three WiFi channels with 320MHz channel width, an important distinction in comparison with Europe.

Why is Wi-Fi 6E worse in Europe?

Having fewer channels out there to broadcast with routers, Wi-Fi Mesh methods or skilled Wi-Fi entry factors, implies that we’re going to have interference with different wi-fi networks, whether or not these of our neighbors or our personal Wi-Fi entry factors. that use 160MHz of channel width. When we’ve little bandwidth out there, however many wi-fi networks broadcasting, we can have:

  • Interference with neighboring Wi-Fi networks. That is the principle drawback, as quickly as our neighbors additionally use this 6GHz frequency band, both with the Wi-Fi 6E normal or with the longer term Wi-Fi 7, every wi-fi community might be configured in automated mode, choosing the free channel out there. We should keep in mind that with 160MHz of channel width we solely have a complete of three channels out there, due to this fact, there’ll come a time when a neighbor selects the identical channel as one other, and it’ll trigger interference.
  • Interference with different WiFi APs. When community directors configure a WiFi wi-fi community with entry factors, it’s important to pick channels that don’t overlap one another, to keep away from self-generated interference. If we had extra channels out there, we might decrease interference from entry factors, and be capable to broadcast at full energy with none issues. Attributable to the truth that we solely have 3 channels of 160MHz, we must “play” with the emission energy so that there’s not an excessive amount of interference.

By having interference in a wi-fi community, as a consequence, we’re additionally going to have:

  • excessive latency: There might be events the place we’ve a excessive latency of the connection, as a result of we must resend the transmission made. When there’s lots of interference in a WiFi community, we are going to discover sporadic “lags”, and even steady if the interference is simply too excessive.
  • Sluggish pace: one of many foremost traits of interference is that the true pace that we’ll acquire by way of WiFi decreases loads. Relying on the extent of interference we’ve, we are able to lose greater than 50% of the WiFi pace that we often have.
  • Cuts within the connection: It’s potential that at sure occasions, particularly if we join removed from the WiFi router or WiFi entry level, we’ve cuts within the WiFi connection.

As you have got seen, Wi-Fi 6E works clearly worse in Europe than in the US, the place they’ve extra bandwidth out there to connect with the wi-fi community, and due to this fact much less interference with different Wi-Fi networks. In fact, the longer term Wi-Fi 7 normal may also have related issues, except Europe allows the remainder of the 6GHz frequency band just like the US does.
