DTEST option- Digital signal analysis and automatic classification

Realizing that further development of radio monitoring devices should include analysis and automatic classification of known communications standards, "RadioInspector" software developers have developed an option of digital signal analysis - "DTEST" ("Digital Test"). This option is designed for digital (software) demodulation of the most common communication standards and radiation classification in accordance with these standards. This option is very simple to use: you should set the cursor on the signal you want to explore and push the button. The program tunes the device to the cursor’s frequency, receives necessary data and performs IQ signal demodulation for a given communication standards. The result of demodulation and signal classification will be displayed on the screen.
This option uses an array or a stream of IQ data transmitted by the device. The current version of "DTest" option you can find implemented demodulators of the following communication standards:


  • AM and FM analog signals

  • DECT


  • GSM

  • 3G

  • 4G

  • BlueTooth

  • Analog TV signal PAL / SECAM / NTSC (displaying video)

  • APCO25 (voice demodulation)

  • DRM/MOTOTRBO (voice demodulation)

  • AM and FM analog signals’ demodulation

AM and FM analog signals demodulation is possible only for devices that send a real-time flow of IQ data (currently it is the only one software defined). Demodulation is possible in any frequency band – from the maximum device provided down to 200 Hz. For AM signals there is a possibility of phase-locked loop.


Demodulator of DECT signals provides detection of base stations’ addresses (RFPI addresses) and attached handsets which are in active mode (talk mode). For each base station and the active handsets, signal level is determined in order to be able to perform their search using amplitude direction finding method. List of legal addresses a DECT base station lets to define new DECT voice data channels in a controlled premises, which can be used as radio microphones. The program does not perform voice demodulation as DECT uses different methods of data encryption.

TETRA signals demodulation determines the values of MCC, MNC, ColorCode and other signal parameters. These parameters may be used for monitoring of TETRA transmitters use legality. If the "DMO" mode is in use ("DMO" mode is a mode of 2 handsets direct connection with the ability to activate one handset from another) the program pops up a warning message about "DMO" mode. This mode can easily be used for creation and activation of the radio microphones. The program does not perform voice demodulation for TETRA standard.

GSM/ 3G/ 4G

Using this software-based demodulator the parameters MCC, MNC, LAC, CI, sector, TCH data channels linked to the analyzed BCCH channel and neighboring BCCH channels can be received.  
Knowledge of these parameters allows determining the topology of GSM network (GSM450, GSM850, GSM900, GSM1800, GSM1900).

The legal bases stations’ list of GSM standard and GSM signal level analysis allows identifying the operation of "substituted" base stations which can be used in the interception of GSM traffic. The program does not perform voice demodulation of GSM standard.

BlueTooth signal software-based demodulator allows to determine the addresses (LAP addresses) of the BlueTooth transmitters which are switched on and in an active state transmitters operating in the beacon mode - that is, periodically broadcasting personal data), or transmitters working in transmit mode. There is an estimation of the transmitted traffic. According to evaluation of transmitted data, a volume transmitted data type can be defined, it is can be voice data, burst or file transmissions. List of legal LAP addresses can be used to identify a new BlueTooth transmitter in a controlled premise, where radio microphone can be found. Assessing the level of the signal can be used to search for BlueTooth transmitter with a given LAP address.

Analog television PAL/SECAM/NTSC

Software-based demodulator allows classifying the analog TV radiations when navigating on it by cursor on the graph to display panoramas and display the video in a separate window.






















Picture 6  - Radiation analysis (Analog TV)

When displaying a TV signal the program defines a TV standard and synchronizes video according to a certain standard. At low signal/noise ratio, if the program can not synchronize the image and if video coding is in use, the manual locked loop of lines and video frames is allowed.

The APCO25 standard signals software-based demodulator for "DTest" option has been created. The APCO25signal’s software-based demodulator allows classifying APCO25 radiation when navigating the cursor on the trace panoramas; to determine the sources and destination addresses of the messages; to determine the network ID and demodulate the voice if coding is not used.

The DMR signal’s demodulator allows classifying DMR radiation when navigating the cursor on the trace panoramas; to determine the sources and destination addresses of the messages; to determine the network ID and demodulate the voice if coding is not used.

For easier use of the RadioInspector "DTest" option, a special software tool has been created. This tool automatically classifies signals that exceed thethreshold. It is used to automatically  identify the well-known communication standards: DECT, BlueTooth, GSM, TETRA, APCO25, DMR and Analog TV. Now the operator simply selects "Signal Classification of Common Signals" in order to display analysis results in the list of detected signals.

RadioInspectorWIFI-GEO –detects all running devices and their relationship with mapping the route and places of discovery. It is designed for stationary and mobile usage.

Operation principle

The system scans all Wi-Fi channels in the 2.4 GHz and 5GHz range, determines and stores in memory MAC addresses of data source
and receiver, determines the signal level

and analyzes the amount of data transmitted. Fixed route (GPS tracker) and the geographical coordinates found on the route, Wi-Fi devices. The system works autonomously for data collection. It does not require a computer to work. Work begins when the power is turned on.

The stored data allows to estimate the activity of each device for a long period of time (a month or more), to identify patterns and regularity
of work and to estimate the amount of data transmitted at different times of the day.


The system consists of receiving modules that can operate without connecting to a computer around the clock. When you connect them
to your computer, RadioInspectorWiFi software downloads data from receiving modules, analyzes and displays on the map, in graphical and tabular form data on active Wi-Fi devices, their connections with each other (who

and to whom transmitted data), signal levels
and the amount of data transmitted, displays
the route, the location of detection of Wi-Fi devices. The software can be connected in series or in parallel to any number of hardware modules via LAN interface. The operator can receive data about Wi-Fi devices in real time when connected to the receiver module.
