Support for more 5GHz Channels


  • Hello,

    it would be nice if the device would support more channels in the 5GHz requency range.
    At the moment only the channels 36-48 are possible.
    One network alone (VHT80) already occupies all channels.

    Even the cheapest consumer devices nowadays supports at least the channels 52-64,
    mostly also the higher ones like 100-140.

    Thank you,
    greetings

    Amplifi HD is supporting all the 5 GHz channels but are limited by country. If you change country to US you'll see more channels.


  • Really? That would be awesome.
    Can somebody please confirm this?

    Although I would violate the law and also maybe had problems because
    after all wifi is a bidirectional connection and my wifi devices
    (with the right region setting) have a lower transmit power.

  • @h-pylori Yes, it is correct. My Amp goes to 161 on 5GHz. However, setting the device for the wrong region is not a good idea.


  • @hanz-shcaerp It's customer responsibility to set correct country code. Also, some devices may fail to connect if you set wrong channel. For example, Samsung Galaxy smartphones in EU are known to avoid channels 149-165.


  • @Hanz-Shcaerp
    Thanks for the information!
    So the DFS channels (U-NII-2A, U-NII-2C) are also available?

    @Dmitrijs-Ivanovs
    You're right! Besides that the U-NII-3 channels (149-165) are here in Europe only for SRD (Short Range Devices) allowed.

    Ich hope ubnt will change this with a future update.
    For a device which is officially sold here the current situation is a little bit unappeased.

    These channels will be available in 2.8.x version in the following countries: Germany, Netherlands, Spain, Bulgaria. But you will need to select those channels manually (they will never be selected automatically because of low power).


  • @Dmitrijs-Ivanovs
    Thank you for the information!
    But as you already mentioned, these channels has low transmission power and also compatibility issues.
    Much more interesting would be the channels 52-64 (U-NII-2A) and 100-140 (U-NII-2C)!

    I almost can not believe that a "prosumer" product in the year 2018 only supports 4 channels.
    If this would be a no-name el cheapo consumer junk - ok, but for a device from an renowned brand manufacturer it is at least a bit "surprising".

    Still enough for most practical purposes.

    Of course we have considered these channels. But these have much more technical implications - especially for product such as Amplifi. On the other hand, very few customers would benefit from it because channels 36-48 are enough in vast majority of cases - especially in a typical residential setting.

    Just 25mW + possible compatibility issues... no thanks!

    I have a different opinion. How many of these 4 channels are used @VHT80... yep all of them. 😞
    If it was a single/stand-alone cheapo ap/router in a environment without direct neighbours (because a lot of the isp routers using the channels 36-48 by default or even exclusively) ok, but for a mesh system its a bit disappointing.

    Do the mesh points also only using these channels for their communication between them, or are they using different ones and/or also simultaneously the 2.4G band?

    Our current generation of routers and meshpoints have only two radios - 2.4 and 5 GHz. For this reason, the same channel is used for backhaul and user service. Meshpoint can use only one for backhaul at any time - 5 GHz is default.

    But even if we had another 5 GHz radio, operating on DFS channels in the same subband (like ch36 for users, ch100 for backhaul) would be difficult for RF-related reasons.


  • Hi @Dmitrijs-Ivanovs

    I understand, so it is basically nothing else then a repeater.
    At least that's what we called it before the whole mesh hype. 😉

    But even if we had another 5 GHz radio, operating on DFS channels in the same subband (like ch36 for users, ch100 for backhaul) would be difficult for RF-related reasons.

    Apart from DFS, to what extend would that be the same band?
    Your example (additional 3rd radio; ch36 for users, ch100 for backhaul) imho would be fine.

    This kind of discussion goes beyond the scope of our current HW platform.

    I get it, it is a consumer product but I was just wondering what you said.
    At the end unfortunately it does not seem to be the right product for me.

    Especially since with a 3rd party router the mesh point seems to can only rebroadcast one single network.
    This means in such an environment it is basically a single band repeater... puhh.

    I was hoping having found an alternative for end users instead of going with a full UniFi setup (which is
    not so easy to update for an end user, requires an controller and has no wall pluggable repeater).

    Thanks anyway,
    regards
