Hello,
Can someone advise me which access point mikrotik capable of covering an area of 2200 square meters (University), with 2000 people who can connect almost at the same time?

forget about a single AP

and

is 2022 forget about only 2.4ghz

Use 2.4 GHz and 5 GHz both at the same time.
Use 20-MHz wide channels.
In the center of your area, you will need about 6 APs with tight small sector antennas facing out.
On the outside border of your area, you will need 6 to 10 APs with tight sector antennas facing in.
All APs need to be in bridge mode , and you backhaul everything to your NAT router.
All APs ( 2.4 and 5 GHZ ) need to have the same SSID ( and key if you will be using a key ).
Consider using bandwidth limiter so that no one single person/client can consume all the bandwidth an AP can deliver. ( Something like PfSense Walled-Garden / Captive-Portal --- Where you set the maximum bandwidths per each MAC address that connects to your wireless network ). I would set it for something like 4 to 8 Meg down and 256-k up per MAC. This way , everybody has a fair portion of bandwidth that is not chocked off by a few abusers.

I assume this if for a temp coverage area such as an outdoor event.
If this is for homes, then you really need to re-think about using fiber , because there is just not enough frequency spectrum to run 2-thousand wireless connections and pass 25-to-150 Meg of traffic to 75 percent of your active bandwidth users. 2,000 users consuming 10-Meg is 20-Gig , there is no simple wireless solution to deliver that kind of reliable bandwidth.

For backhaul do you mean you expect the APs NOT to be wired to a central router and they will have to be connected via ptp connection to the main router?

So are you thinking Cube60 PTP connections, ethernet to combo 2.4/5ghz APs locally???

Coverage area is useless, provide a GPS point to get some ideas from Google Hearth.
Is everything flat or does it have obstacles? Is it a square? Is it a building?
If you have a 50m × 50m place it's not really that big, but 2000 users on 50m × 50m are too many...
Not even the best competitor can cover everything for 2000 users with a single device.

Behind the various APs necessary, there is also a Core Router that manages all the connections to be considered...

If is a square, all flat and AP can see eachother, is a big mess and never work correctly as expected...
Must be used some cell-like method with many AP with low gain and low tx power, connected by wire.

There is some kind of prison.

Don´t use MikroTik access points for high density.
