The operation of the proposed device is as follows.

After turning on the power, modules 1-6, 8-10 are checked and connected to block 7 for interface and control of modules. At this stage, information about the last known state of modules 1-6, 8-10 is collected and registered in the database of block 7. Next, depending on the tasks to be solved, the set of modules required for operation is determined. If panoramic view module 1 is selected, the required frequency ranges in which frequencies will be scanned are configured. Data about the configured frequency range is transmitted to block 7 for pairing and controlling modules to ensure correct control of module 3 for assessing base station parameters and module 5 Wi-Fi and Wi-Fi 6E, as well as module 6 Bluetooth and ZigBee. Information from modules 3, 5 and 6 is transmitted to the interface and control unit 7 and sent to the panoramic view module 1. Panoramic view module 1 displays the received data in the form of a radio frequency spectrum, which is monitored by the operator.

To solve problems of monitoring radiation with reference to certain standards, module 2 of frequency-amplitude detection is used. When this module 2 is launched, the controlled frequency ranges are determined, this information is sent to block 7 for pairing and controlling the modules. Next, unit 7 for pairing and controlling modules launches module 3 for estimating base station parameters. The collected information about the signal situation is transmitted to block 7 for interface and control of modules and is used to determine the detection thresholds for new radiation. The frequency-amplitude detection module 2 outputs the received data in the form of a radio frequency spectrum through module 9 and compares the received data with a set threshold; if the signal exceeds the set threshold, the operator receives an information message and an audio alert. Information about exceeding specified thresholds and the radio-electronic situation is entered into the database of block 7.

When module 3 evaluates base station parameters is started, module 3 scans the radio frequency range, detects data packets and identifies base stations. Block 7 for pairing and controlling modules receives information about the parameters of base stations with the formation of a general table of operating frequencies for base stations. The module interface and control unit 7 transmits the received information to the base station emulation module 4 to configure the necessary parameters, for example, frequencies and base station identifiers.

When you start the base station emulation module 4, the standards and ranges of the base station, modes and duration of operation are configured. The module interface and control unit 7 receives information about the launch of the base station emulation module 4 and the parameters of the base station. The base station emulation module 4 receives information about the identifiers of the mobile terminals. All information collected by base station emulation module 4 is stored in the database of block 7.

When Wi-Fi module 5 and Wi-Fi 6E are started, module 5 scans the radio frequency range, detects data packets and identifies devices and reports information about registered access points to unit 7 for pairing and managing modules. The operator receives information about registered Wi-Fi and Wi-Fi 6E access points and decides on the duration of scanning or monitoring of Wi-Fi devices. The information received by Wi-Fi module 5 and Wi-Fi 6E is stored in the database of block 7.

When Bluetooth and ZigBee Module 6 is started, Module 6 scans the radio frequency band, detects data packets, and identifies Bluetooth and ZigBee devices. Next, the information is transferred to block 7 for interface and control of modules. The operator receives information from the unit 7 for pairing and controlling modules about registered devices and determines the operating time of the module. The information received by module 6 Bluetooth and ZigBee is stored in the database of block 7.

The device is placed in a room intended for negotiations in order to identify channels of information leakage by monitoring the signal environment created by cellular communications. To do this, scan the base station signals using module 3 for estimating base station parameters. Module 3 for estimating base station parameters creates a list with data on the parameters of GSM/UMTS/LTE base stations. Based on the results of module 3, information about 7 base stations was recorded in the GSM standard, 5 base stations in the UMTS standard, and 11 base stations in the LTE standard. The operating time of base station evaluation module 3 was 7 minutes. The collected information about the parameters of base stations is used in the base station emulation module 4 to determine the standards and operating ranges of the base station emulation module 4. Then the operating mode of the base station emulation module 4 is set according to a given algorithm. Next, the base station emulation module 4 searches for identifiers of mobile cellular stations in the communication standards and bands defined in the scenario. When registering mobile cellular terminals in the base station emulation module 4, the identifiers of the mobile cellular terminals are displayed.

The device is placed in a room intended to accommodate sales department employees in order to check the room against information leaks through technical channels and search for devices for secretly obtaining information.

The inspection of the premises is carried out in several stages. At the first stage, the verification begins with a search for devices for secretly obtaining information that use the infrastructure of a mobile telecom operator to transmit information. To do this, the collection of signal conditions is started. Base station evaluation module 3 provides scanning of selected standards and ranges with the generation of data on the parameters of base stations of GSM/UMTS/LTE/NR standards. The GSM standard contains information about 15 base stations, the UMTS standard - about 5 base stations, and the LTE standard - about 10 base stations. The operating time of the base station evaluation module was 7 minutes. The base station emulation module 4 uses as initial data to configure its operation the collected information about the parameters of the GSM/UMTS/LTE/NR standard base stations received by the base station parameters evaluation module 3.

Having determined the necessary standards and ranges for the operation of base station emulation module 4, the collection of mobile terminal identifiers is started. There are 7 mobile terminals registered in the GSM standard, 4 mobile terminals in the UMTS standard, and 11 mobile terminals in the LTE standard. The operating time of base station emulation module 4 was 30 minutes. All collected information is recorded in the block 7 database.

The second stage of the test begins with the launch of module 2 of frequency-amplitude detection. Scanning ranges are determined in order to detect emissions from means of secretly obtaining information in them. To determine the detector response threshold, module 2 continuously evaluates the signal level in controlled ranges. When the module 2 detector is triggered, an information message is generated. Next, the panoramic view module 1 is launched to carry out continuous scanning of a given spectrum range with the construction of a time-frequency diagram. In parallel, modules 3 for assessing the parameters of base stations, module 5 Wi-Fi 6 and Wi-Fi 6E, module 6 Bluetooth and ZigBee are launched. From modules 1, 3, 5, 6 of digital analysis, the collected information about the parameters of the detected signals is transmitted to module 1 of the panoramic review and is displayed in the form of markers on a time-frequency diagram on the screen of module 9.

The third stage is a digital analysis of the recorded signals in module 5 Wi-Fi and Wi-Fi 6E, module 6 Bluetooth and ZigBee.

Next, module 6 Bluetooth and ZigBee are launched, we obtain data on device identifiers, followed by comparison of the recorded results with the panoramic viewing module. All collected information is recorded in the block 7 database.
