Do smartphones implement collision avoidance techniques at probe requests level ?
I'm wondering if placing three smartphones together in an isolated room would alter their behavior compared to when they are operating individually (especially in the probe requesting level). I suspect that their behavior might indeed change due to the presence of a collision avoidance mechanism. Do you happen to have any insights on this? Would the timing or content of probe requests be influenced by the presence of other phones nearby?
Thank you!

Probing behaviour is depend on each vendor implementation and not listed out in great details in public.
Based on CSMA/CA operation, it is of course make a difference if those phones are in one place (more contention) vs if they are in isolated rooms (less contention, assuming they are not hear each other on same BSS)

Thank you for your consideration. I already checked those links. They don’t really answer my question. Thanks!
