Do Mesh networks overlap the same channel?

    Riddle me this: Do mesh networks, any mesh setup - commercial or consumer, share/repeat the same channels?

    Ubiquiti, Google, Cisco Atheros, etc.

    The only issue I have with my multi-AP setup is that they are all on different channels, which forces the client devices to "figure it out" as to rather switch to a stronger AP or stay connected until it just completely drops.

    Wondering if I would gain anything with these new mesh networks.

    You're asking 1 question but you mean to ask different one.

    - Cheap repeaters operate on the same channel, because they only have 1 radio. This is bad, lowers the effective bandwidth for everyone.

    - The higher end products you mentioned probably have multiple radios; they use a 5Ghz channel to communicate with each other "backhaul", and then broadcast an SSID on another channel. This uses more channels but there's less interference and more speed on the network. This is a "proper" solution to the problem.

    - The problem of "sticking" to a router that is too far away is very common. It is caused by a number of issues; mostly it can be resolved by:

    - Lowering the power output on one or more APs, especially on 2.4Ghz
    - Disabling the Lower speed rates (Minimum 18mbps instead of minimum 1mbps). (mostly on 2.4Ghz networks?). This may be challenging to find in your router settings, or absent.
    - Using different SSID names and manually micro-managing which AP you are connected to
    - Settings on the Router or the clients that specifically expedite AP switching
    The advantage of those more expensive products, besides using dedicated channels for backhaul, is they are probably designed with multi-AP roaming in mind, and probably have options to expedite roaming ; some of them might call this feature "Minimum signal strength before the device gets kicked off" or "minimum RSSI"
