Determining the level of wifi signal?

Question

WiFi

Please tell me the cheapest way to get RSSI level data of all corporate devices connected to the network (in particular Ipad).
You can, for example, write an application that sends the signal strength to a centralized server in the background.
Are there any thread solutions / services on the side of the router, without installing client applications?

Answer 1

It seems to me that if the device understands snmp, then it is possible this way and that.
