Wifi + many users?

Question

WiFi

Good afternoon
I ran into a problem. It is necessary to upgrade the Wifi network due to the increase in load. ~500-700 users.
Before that, Cisco AP 1121 was used - 4 pcs.
There was an idea to purchase a Cisco 2112 WLC + 4 AIR-AP1242G-E controller and transfer all points in the LAP to controller control.
The main question remains: will they withstand such a load?

Answer 1

No one can say for sure, because there are a lot of factors:
1. The physical topology of the network
2. Channel overlap (the presence of neighbors)
4. Volumes and characteristics of user traffic
5. Required minimum channel characteristics for a user
Average hospital values: up to 10 simultaneous active users per point.
