Businesses across the UK use Wi-Fi and will also benefit from license exemption in the 5. Additional bandwidth may also reduce costs for some businesses, as it makes it possible to improve their Wi-Fi coverage without requiring additional equipment to achieve this goal. It has no impact to customers selling or shipping wireless products to UK, as this update added some channels in addition to what the European Union already allows.

Band B Channels — Band B is also licence free and can be used both inside and outside.
There are some conditions however: a Band C can only be used for outdoor wireless b Band C can only be used for fixed wireless access FWA points e. Loading Comments Sorry, your blog cannot share posts by email. Now as you can see by extending the channel 10MHz in each direction you have used up 2 x 5MHz wide channels in each direction what would have been Channels 38, 39, 41, This is why these channels are not considered usable and typically aren't selectable on most hardware.
If you were to use them, you could end up with co-channel interference. However, Band A breaks down further into 2 bands. This set of 4 channels allows for 4 non overlapping 20MHz channels or 2 non overlapping 40MHz channels. As long as you keep to the mW output limit all is groovy.
This set of 4 channels also allows for 4 non overlapping 20MHz channels or 2 non overlapping 40MHz channels however DFS and TPC need to be switched on in order to remain compliant with Ofcom regulations. Infact many hardware vendors will force you to have these settings switched on within the firmware when using these channels.
Dynamic Frequency Selection allows 5GHz hardware to operate within the same frequency space used by radar such as military and weather. If DFS is enabled on an access point or bridge unit in access point mode then the device when it first selects a channel will initially listen for a short period of time to ensure that it is not picking up any radar signals.
If radar is detected then a different channel will be used. If the airwaves look clear on that channel then it will remain on the channel. However if radar is later detected then the device will shift to another channel. The access point will use protocols specified in Once a device has moved away from a channel which radar has been detected on then it will stay clear of that channel for a defined amount of time. This is due to some devices only supporting a 20MHz channel.
The 2 channels are known as the Primary and Secondary channels and they must be adjacent channels. The secondary channel may be above or below the primary. If a device only supports 20MHz wide channels then it will connect to the primary channel.
