On a shared civic Wi-Fi RF medium, guest bulk downloads and employee VoWLAN compete. How should QoS be applied so voice remains protected?

Short Explanation
Guests bingeing big files are the slow moving truck; voice is the ambulance. Park the truck in the scavenger lane and keep the ambulance in AC_VO with DSCP mapped all the way through.
Full Explanation
WMM access categories and DSCP-to-WMM mappings prioritize latency-sensitive traffic. Guest bulk transfers belong in background/scavenger treatment so they yield contention opportunities to AC_VO voice. Elevating guest into voice, flattening EDCA, or cloning voice WMM onto guest SSIDs removes the priority differential the design needs.
