Serving APs at a busy city convention center cannot spend enough time off-channel without hurting client performance. Security still needs continuous multi-channel visibility. Which WIPS selection follows?
Select an answer to reveal the explanation.
Short Explanation
If serving radios are glued to the client channel, they cannot moonlight as full-time security scanners. Overlay sensors carry that load so fans and attendees keep airtime. Wired DHCP tricks do not see RF rogues.
Full Explanation
Integrated WIPS can under-scan when serving radios must remain primarily on-channel for capacity. Overlay architectures dedicate sensors to continuous off-channel monitoring without taxing client-serving airtime. That tradeoff drives overlay selection in dense, performance-sensitive venues. Non-RF controls such as DHCP snooping do not replace wireless intrusion monitoring.
