Max agregated over the air speed is the max speed of the AP. Real speeds must take in account the on-the-air protocol overhead (a good guess would be up to 90% under ideal conditions, real world implies less).

No. You asked for the maximum theoretical speed. Which assumes all clients connected at maximum.
In your case, it depends on how much traffic goes to each client using the specified speed. So it is really not quite predictable. Not sure about NV2, but you can imagine each packet as a variable time slice at a specific speed for CDMA style media access, which is almost unpredictable, and as a fixed length time slice on TDMA media access, which can be somehow calculated if you have all the data. But I think it is safe to assume wireless PtMP as a best effort system, with a load dependant maximum bandwidth.

Use simple queues on the AP or termination router to artificially slow speed. The TX/RX rate is kind of the theoretical given current link conditions for that client.
Yes but my question is more focused on the stability and latency od the link. In noisy environment is better to use high speed (so overdimensioned) for the wireless link or a lower speed (that fit the requirement speed of the clients)?
15 clients connected at 24mbps will have at maximum 24mbps agregates speed. The same clients connected at 150 mbps will have 150mbps maximum agregated speed.
But if they are mixed, the agregated speed will be variable somewhere in between, depending on the traffic of each client and on how well the chipset can handle mixed speeds. It is even possible that the AP speed will fallback to the slowest client.
Thanks, the mixed example is what I was searching for.
