Inspectors’ VoWLAN handsets in a dense city annex ping-pong between APs every few seconds, creating audible gaps. Coverage overlap was increased aggressively after a complaint about dead spots. What should the expert tune next?
Select an answer to reveal the explanation.
Short Explanation
Too little overlap drops calls; too much overlap makes phones play musical chairs. Those rapid AP hops punch holes in voice. Pull the cells back a bit and calm the roam thresholds so inspectors stay put until a real move is needed.
Full Explanation
Excessive coverage overlap and aggressive roam thresholds cause ping-pong roaming that interrupts voice media paths. Balancing neighbor RSSI differentials and roam parameters reduces unnecessary transitions while preserving required coverage. Adding co-channel APs, disabling QoS, or opening authentication does not correct roam thrash and introduces new risks.
