Ok thanks, just having a tangle with Microtik ATM trying to get them to change all the AX devices to 200mw from 25mw in that range.
Sorry If I went a bit side-ways on the topic.

Have you allowed for antenna gain? The 200mW is the product of the initial signal, amplification and antenna gain. 200mW EIRP is the same as 25mW with 9dBi antenna gain. And yes, I am a sad, sad, man for knowing that.

Antenna gain 4.5
Infact at that frequency 5

Ignoring the Asus issues as already mentioned, the main point here is if those APs only use their wired backhaul for data to the router/network then they aren't 'mesh' but just APs that support roaming between them (and there are different levels of that). This is different from APs using wireless between each other for data transmission to the main router/network (whether separate connections or shared with clients).

Mesh is a term that's getting overused from its original wireless backhaul roots.

i have this and have given up with wireless backhaul. One of the boxes just stops working correctly until i either reboot or have to add them back together, i have had these since they were released and so many firmware and still it happens on latest.
I haven't tried them on wired backhaul though. I ended up moving the single box and now coverage is ok across house.

What’s the device? What WiFi card is fitted? Tx-power 9 could be anything from 5mW to 65mW depending on what chipset card you have. If you want more transmitter output you can just change the country to an unregulated location and it will blast your WiFi clients with its true maximum power but I promise you, you want less power, not more.

I’m not sure what page you think we should be on, but hopefully I understand enough to work it out anyway.

A 5dBi gain antenna would need 104mW of input power to give you a 200mW EIRP. That unit has 2 antennae of 4.5dBi. You can’t technically just sum two logarithms but the effect in this case is basically 9dBi so I think you’ll find that 25mW input power is all you’ll get.

Mesh is just a term for dynamic network topology, common in wireless on ethernet is cover by a number of standards like 802.1aq

Mesh is a standard all of its own. The underlying technologies are all the 802.11 but 802.11s incorporates something called the Hybrid Wireless Mesh Protocol and the clue is in the name Wireless Mesh. You can be slapdash with your terminology if you like, but Mesh is wireless backhaul only.

So my mesh is no longer a mesh of interconnected devices that communicate with each other when I use a wire between node, it some how changes into something else?

Sorry I thought it was quite obvious from what I posted, that @5725-5805 I should have Ouput power of 23bdm 200mW for the UK but I'm getting 14dbm 25mW which is wrong. Hence the question.

Yep, it’s a network.

I’m totally confused now. First, you have 2 antennae, both transmitting, so you have to allow for that.

Are you saying that you are seeing 9dBm as the transmitter output power in the Miktotik user interface? And then you are adding 9+5 to get 14dBm? Even if you do the maths like that, you need to add another 5dBm for that second antenna.

I’d be absolutely stunned if MikroTik have got their sums wrong on this.

It is a network, it’s a wireless backhaul network. As I said, you can go on being slapdash with your terminology all you like. But the Mesh standard IEEE 802.11s only allows for wireless backhaul.

Think about it. If that wasn’t the case, why do Ubiquiti access points have a special wireless backhaul mode called…. Mesh?

Lets keep it simple whether it's two @ 4.5 or 9 and the other 4.5 is factored in for example.
They don't quote 4.5 per antenna it's just 4.5 So by their reasoning 18dbm+5dbm=23 200mW Output Powwer.
So the 18dbm? power figure is what that band should do max for the frequency being used in the UK but it's 14 ?
Lets move frequency as seen below to 5170-5250/23/Indoor so we move to 5220eeCe then look at the power level quoted which is now 18+5=23 which is what is quoted in the radio reg-info. You can't add it up any other way.
Mikrotik have agreed it's wrong and may change it in their older AX, devices but it will be implemented in the newer stuff.
