For reference, in the unlicensed Ubiquiti gear that I've used, the point-to-multipoint latency is variable with the signal quality of the connected stations. If all client stations have good, clear signals, the latency is around 1-2ms. But that can spike quickly if you're dealing with interference or other causes of low SNR.
