Posted here about some concerns related to the hAP ax3 and poor signal coverage / power output (ultimately, leading to poor performance). http://forum.mikrotik.com/t/hap-ax3-preventing-buyers-remorse/166233/1 As I mentioned in that thread, a hAP ax3 replaced an AirCube and signal strength to the c…

If you ever compare hAPac2/ac3 with hAPax2/ax3, then in Europe do limit the channels between “5180-5700”, or you get the SRD low power channels in the ax devices. Low power, also see “status” to check what you got. [Klembord-2.jpg] If you limit the channels to the range the ac AP’s can handle , t…

it cannot be from antenna positions or different channels. It IS from different channels. The ac 5GHz signal is 40 times (16dB) stronger than the ax signal when just using the default settings on both. And 2.4GHz. I don’t believe you get 574Mbit/s in ac (VHT) in 2.4GHz, where the largest ban…

Not out of the woods yet, with the ax wifi 2.4GHz. It enables b-protocol with “ax” set. Is this including the 1Mbps basic rate? What a waste of airtime! Hope other AP’s won’t pick up that regression to b-protocol. Seems not the case so far with regular n-setting on 802.11n/ac devices with WLAN driv…

There are several posts now on Tx power and the ax range. My head’s spinning reading them all. I’ve never had to worry with power on UBNT access points but that’s either because a) they just get it right or b) I don’t get so anal with them :wink: RouterOS does encourage experimentation. Something ce…

You want to be in the red zone of this pattern. The Z-axis is the physical antenna. So one up and one flat, is what is expected to be in the hAP ac2/ax2 . The red zone, high gain, is both for TX and for RX. Klembord-2.jpg Copied from interessting Cisco document : https://www.industrialnetworkin…

Omnidirectional is 2D omnidirectional, in a plane perpendicular on the antenna. It can never be 3D omnidirectional in the sense of equal antenna gain. That kind of antenna does not physically exist. It is called an isotropic antenna. Antenna gain here is by definition 0dB (zero) https://www.scien…

There is another thing to keep in mind when comparing performance in different channels of same frequency band: real antennae, specially so the simpler ones (such as simple dipole), don’t have constant antenna gain accross the whole supported frequency range. The specced number is the highest gain i…

Can we think of an objective test for those antenna? Have been playing around the whole evening, comparing my hAP ac2, hAPac3 and new hAp ax2. (hAP ax3 I manage is very remote, with antennae removed, used for all but AP) Scanning my neighborhood 2.4GHz with those AP’s and with inSSIDer software o…
