Simulating RF without a hardware(like ap/antenna) may be challenging.

No, but you could simulate the effects with netem in Linux, which can simulate variable delays, packet loss, duplication and re-ordering.  It's descended from a tool that NIST built a while ago, and one company I worked at before Aerohive used NIST's tool to discover some pretty subtle fragmentation bugs.

True, simulating traffic from a client to an ap to the controller might be useful.

Simulating wi-fi client traffic can be done with mac with the Developer tool Link Conditioner.. This is very handy if you want to test lossy traffic conditions. You can find this under Xcode > Open Developer Tool > More Developer Tools.

There are a couple of commercial network traffic simulation tools for Wi-Fi clients but they are VERY expensive.  Normally they are used by WLAN vendors to test their equipment, rarely are they used to test WLAN deployments.

In all my years in this business, the only time I have seen commercial test tools used by a customer (as opposed to a magazine or analyst test) have been in super-well known household-name type companies doing their own intense bakeoffs.  And even then, it was testing of a pilot deployment in a lab building, not on a network that was being used to actively support business traffic.
