Which devices today use 3x3 ?? .

4×4 MIMO is now common on high-end phones like Apple’s iPhone XS and iPhone XS Max. Samsung’s Galaxy S9 and S9+ also support 4×4 MIMO, as do Google’s Pixel 3 and Pixel 3 XL phones. They can all support four separate data streams at once when connected to a cellular network that offers them.

I cant believe it is 2020 and Mikrotik are still using a 2.5dBi antenna on the 5Ghz radio.

It should be 4dBi minimum. This will provide better performance for a wide range of devices.


Hopefully they engage someone like Lynwave to design higher performing antennas on their WiFi products.

But concur the iphone 12 does have 4x4 mimo.

The 2.5 dBi antenna has its benefits. Certainly for indoor usage, and if you want to get signal in an adjacent room or floor.
The places where you have a lot of reflection and where to path through the wall is uncertain and unknown.
Due to the low gain the spectrum pattern is almost spherical. (Thick doughnut). The higher gain antenna emit much less total energy, in a thinner doughnut pattern.
Much less overall energy because the EIRP requirement sets the max radiation is the direction of the most gain. Other directions are just weaker.

Do the experiment , set a 2.5dBi AP (hap ac2= new wAP ac(2)) on that other floor and try to connect, and check your signal SNR and CCQ.
Then take a 7.5 dBi device (Omnitik 5 ac) and test again. The outcome will be very disappointing even if you turn the AP to maximise the spectrum direction.
Take a 16 dBi antenna device (SXTsq, SXT sa5) and you will be more disappointed.

Free field outdoor is a different story and different outcome. It all depends. Sometimes high gain antennas is what you need, sometimes not.
(I saved a wifi environment with long range outdoor AP's, by replacing them by wAP ac, with short range chosen on purpose)

If you want/need higher dBI then hAP ac3 and Netmetal ac2 are there to be used.

As for your suggestion about using hAP ac3 and Netmetal ac2, while these are decent products in their own right, they cannot be used in the place of a cAP ac or wAP ac as they are not "all in one" products that can be tidily mounted to a wall or ceiling, and not suitable for mass deployment in Multi-Dwelling-Units or Enterprise. For one, they will stick out like a dogs balls.

Or worse a monkey with a hard banana ;-PP

While I agree with some of your comments, my experience with tens of thousands of units of wAP ac, hAP ac Lite, hAP ac2 and cAP ac is that while they have decent performance at 2.4Ghz when the spectrum is clear, the "real world" performance in 5Ghz is much worse than other brand AP's with higher gain antennas. This is not so much about the AP transmitting, a small antennas can be overcome with more TX power. It is about receiving the signal back from the clients.

Are you saying that the likes of Aruba, Cisco, Extreme Networks, Ruckus, Fortinet, Aerohive and Cambium are wrong to be using 4 to 7dBi antennas for 5Ghz in their indoor access points ?

All I know is that an EAP245 from TPLINK easily outperforms a capac.

Antenna Type 	Internal Omni
2.4GHz: 3 × 4dBi
5GHz: 3 × 4dBi

People look over my shoulder when i am working in caps-man...

"Damn... imagine if that could control good radios."

https://www.tp-link.com/en/business-net ... eap265-hd/ is the new high density one.

.
Maybe they should make alternative wireless packages (has happened before)

Not sure why Mikrotik and Normis have had lobotomies on this issue...
