The correct statement is that Juniper APs have a dedicated radio to scan for rogue and honeypot APs. The official Juniper Mist documentation specifies: "Juniper APs include a dedicated scanning radio to detect rogue, neighbor, and honeypot APs and their clients... The dedicated scanning radios operate on 2.4, 5, and 6 GHz Wi-Fi bands." This third radio operates independently from the client-serving radios and enables continuous threat detection on all Wi-Fi bands, enhancing security and allowing real-time performance adjustments. BLE radios are used for location-based services and asset tracking, not for rogue AP detection.
Client-serving radios can also scan, but detection is always enabled and optimized by the dedicated radio.
