BQX-B02

The SZMID - BQX-B02 is China’s first portable full-band, full-system, real-time digital wireless signal detection and intelligent analysis equipment. Independently developed to support all three major domestic communication operators’ standards and protocols, it is optimized for various power frequencies and communication protocols, providing high-precision detection, tracking, and prevention of unauthorized wireless devices. With a comprehensive detection range of 0 to 9GHz, the BQX-B02 covers all wireless communication bands currently used both internationally and domestically, ensuring compatibility and adaptability across diverse environments. The device supports full protocol detection for 2G (GSM, CDMA), 3G (WCDMA, CDMA2000), 4G (TDD, FDD), and 5G networks, along with signal detection and early warning for communication devices operating in specialized bands such as 315-433MHz, 800MHz, 1.2GHz, 2.37GHz, and 5.8GHz. This versatility enables it to accurately identify and localize wireless signal sources, making it ideal for a wide range of surveillance and counter-surveillance scenarios. The BQX-B02 is equipped with advanced Wi-Fi probe functionality, supporting dual-band 2.4GHz and 5.8GHz protocols. It can differentiate between hotspots, connected devices, unconnected devices, and hidden camera devices across all Wi-Fi channels. In addition, it features a powerful Bluetooth signal detection capability, which identifies and locates all types of Bluetooth transmitting devices. Utilizing real-time spectrum monitoring and display capabilities, the BQX-B02 visualizes detected signals through a sophisticated algorithm, allowing users to record the spectral signal background and perform background comparisons for comprehensive analysis. Its deep learning algorithm processes signal data based on type, duration, and intensity, facilitating precise identification and classification of suspicious devices. The BQX-B02’s intelligent early warning system is built on an extensive electromagnetic fingerprint database, which compares detected signals against known device characteristics. This enables the system to provide instant alerts for illegal devices, such as hidden cameras, voice bugs, GPS trackers, and even examination cheating devices, while offering precise location tracking by adjusting the detection distance. For specialized inspections, the BQX-B02 can detect, analyze, and identify the characteristics of various wireless devices, such as mobile phones and Wi-Fi hotspots, ensuring compliance with regulatory standards. The spectrum signal function offers a detailed visualization of the 0-9GHz frequency range, supporting demodulation for multiple communication modes, including AM, FM, OFDM, and 2G to 5G signals. The BQX-B02 also includes an automated test report generation feature. Each inspection session is logged as an event, and the corresponding report, complete with test information and results, can be exported to a computer for further analysis and long-term record-keeping. The device’s fast scanning period of less than 500 milliseconds ensures real-time capture of all wireless signals, while its adjustable sensitivity and detection range (from 20cm to 10m) provide unparalleled flexibility for diverse operational needs. Designed to meet the demands of security professionals, law enforcement, and military applications, the SZMID - BQX-B02 sets a new benchmark for portable electronic surveillance detectors with its high-performance signal detection and intelligent analysis capabilities.
