How to implement the connection of about 100 users to wifi?

Question

WiFi

An event is being planned where they want everyone to have wifi access.
Initial data:
Dedicated Internet channel at 30 Mbps (I understand that 300 kbps per person is not enough, but still)
The area of ​​​​the room where the event will take place is not large. People will stand tight.
From the equipment so far there is only Mikrotik rb2011, I think to connect a couple of unify plates to it.

Answer 1

IMHO.
If we talk about Mikrotik as a router, then the piece of iron has no concept of the number of users, but it has a bandwidth (it is clear that a spherical horse is in a vacuum, but it is suitable for comparison) - Ethernet test results (Routing 25 ip filter rules 31.0 Mbps at a size of 64 bytes). Those. in the worst case, with 25 rules and a small packet size, the channel will not kill the channel. BUT! when using queues, without fastpath it can be bad.
But about wifi and additional unifi dishes ... Just the same problem will be in wifi and air pollution. Again, on conventional equipment (without controllers), it is considered better not to hang more than 10-15 devices per point (if we are talking about a b / g / n point without mimo). But, of course, it all depends on the type of traffic and client activity. In addition, do not forget that if someone connects to the point via b|g or with a dead antenna (meets) or is very far away, but transmits, then it will be bad for all users at the point.
As a solution - more points in the 5Hz range (it is cleaner), turning on only the N standard at 2.4Hz, turning users off at a low signal level on Mikrotiks.
