I. Core Applications

1. Detect unauthorized WiFi APs in classified environments (wireless routers, mobile‑phone personal hotspots, MiFi portable WiFi devices).
2. Identify WiFi pin‑hole cameras and IoT wireless audio‑video eavesdropping devices.
3. Acquire SSID, MAC address, channel, encryption mode and signal strength of APs/terminals; distinguish connected and unconnected WiFi terminals.
4. Perform close‑range localization of suspicious WiFi signal sources to locate physical devices.
5. Blacklist & Whitelist support: whitelist for pre‑approved compliant wireless devices; automatic alert for non‑whitelisted devices.
6. Scan surrounding APs, switch channels to promiscuous mode, and count MAC addresses and RSSI of online WiFi clients under each BSSID.
7. Client Sniffer function: capture Probe Requests and association frames to detect nearby mobile phones and computers.
8. BLE broadcast sniffing: scan nearby Bluetooth MAC addresses, RSSI values and device type codes.
9. WiFi & Bluetooth device localization: locate devices based on signal strength.
10. Target early‑warning: real‑time alert for detected targets.
11. Collision analysis: conduct collision analysis on scan results from different times and locations.

II. Standard Core Functions

1. Protocol Compatibility: Support 802.11 a/b/g/n/ac/ax (full WiFi channels: 2.4GHz, 5.15‑5.35GHz, 5.725‑5.825GHz); compatible with BLE and classic Bluetooth device scanning & identification.
2. Target Identification: Recognize AP hotspots, STA wireless terminals, hidden‑SSID hotspots and WiFi cameras; extract MAC address, signal strength, channel, encryption type and device manufacturer information.
3. Localization Capability: Work with directional antenna for proximity‑based localization via signal strength. Typical positioning accuracy: 2‑5 meters; 1‑3 meters with handheld close‑range searching.
4. Blacklist & Whitelist Management: Import MAC whitelist of legitimate devices; audio‑visual alarm for illegal devices.
5. Task & Report: Record inspection location, operator and timestamp; export audit‑traceable inspection reports in PDF / Excel format.
6. Local Storage: Save scan data offline without external network access; external network connection is prohibited for classified‑site operation.
7. Endurance: Lithium‑battery powered, continuous working time ≥4‑8 hours; portable touch‑screen operation.

Special Features

‑ Optional GPS for location logging ‑ Adopt active signal induction to accelerate localization ‑ Support estimated localization distance and signal waveform display ‑ Support scan snapshot; analyze newly‑appeared, left and co‑occurring terminals to identify persons of interest combined with on‑site observation ‑ Compact, lightweight and concealable design

III. Key Technical Parameters

IV. Important Requirements

1. Domestic‑developed software and hardware. The complete unit shall be domestically manufactured with no overseas core modules adopted.
2. No built‑in 4G/5G cellular module. External network access is prohibited. All data shall be stored locally.
3. Complete operation logs shall be retained for audit purposes and satisfy the ledger requirements for confidentiality inspection.
4. Only passive monitoring and scanning functions are allowed. High‑power jamming or suppression modules are forbidden (arbitrary wireless jamming is prohibited in classified premises).

V. Equipment Limitations

1. Target devices cannot be detected when powered off or with WiFi disabled. Detection and identification are only available when radio frequency transmission is active.
2. Walls and metal obstructions will attenuate WiFi signals, reducing detection range and positioning accuracy.
3. Only WiFi and Bluetooth signals can be identified; wired‑network espionage devices are undetectable.
4. The device performs detection and localization only; WiFi password cracking is not supported.
