BLS Wi-Fi Screen Pro is a system that in data collection and analysis mode does not emit radio signals in any frequency ranges other than electromagnetic emissions of the computer. In signal jamming mode (option) works as an intelligent jammer on all Wi-Fi and BLUETOOTH frequencies and channels.
The System can be used for:
iRevealing the work and the physical location of any type of eavesdropping devices with Wi-Fi module or devices transmitting information via Wi-Fi.
iRevealing the work and physical location of any type of Wi-Fi devices, transmitting within 460 m radius in urban environment (depending on the antennas and antenna block).
iWi-Fi network performance analysis- coverage at different points, traffic and speed, devices connected to the network, business traffic/real traffic and operation of all repeaters, extenders and hotspots of the mobile network. Analysis the real performance of the Wi-Fi base stations with all connected devices.
iDetection of unauthorized access attempts to Wi-Fi networks from external devices whether the attempt is successful or not. The system also identifies the attempt to connect.

iEstablishing the relations between different people and their previous visits to different areas of the city, state, world /depending on the hardware and software version of the Wi-Fi devices used by them/.
iTracking and localization of people and vehicles.
iIdentification of skimming device (a device that steals credit and debit card information from ATMs) and detection/localization of the people or the device, receiving that information.
iJamming of individual base stations or clients, as well as total jamming of Wi-Fi and BLUETOOTH channels.
The system is designed for:
- National Security Services (counterintelligence, anti-terrorism, etc.)

The “BLS Wi-Fi Screen Pro” system includes specialized software installed on a laptop and antenna block (box) connected with USB cable.
The connection of the Antenna block with the laptop is with USB cable.
In addition to the directional and omnidirectional antennas (included in the set), any other types of antennas can be connected to the antenna block trough standard SMA RF connector and antenna feeder.
The Antenna block coordinates the antenna adaptors performance and speeds up the information transfer.
In an emergency mode (broken or missing antenna block), the BLS Wi-Fi Screen Pro can operate with most of the available Wi-Fi USB adapters on the market, as the system has a software module for recognition, coordination and connection of Wi-Fi adapters.In this mode the range, speed and functionality of the system will be limited, but sufficient for most of the tasks.

The results from the scanning in graphic format are in real time and could be changed dynamically. The image below shows the links between clients and the base stations. In red are the networks stored in the client’s memory.
Records preview screen
The system records all the data during the real time (live) scan. By simulating a real time operation and by record preview, all records can be reproduced and the real scan can be repeated, including level measuring and new graphics.
The system allows automatic analysis of the recordings, manual review of a specific recording or multiple selected recordings.
GPS positioning screen
It shows the System’s GPS position when any signal is detected or disappeared.
The links between time, GPS coordinates and signal/ device information are displayed in tabular format, with option for subsequent review and analysis. All positions (spots) with the time when a specific device has been detected could be graphically displayed and determine its location within 25-30 m accuracy.
The system has a built-in offline map. When the system is online it uses two independent map servers that updates respectively every hour and in 24 hours.
The software has built-in HELP tools in the form of graphics and texts.
Wi-Fi and BLUETOOTH Jamming (optional)
As a result of the work of BLS WI-FI SCREEN PRO System, the real status in terms of available base stations, clients, paired and single devices operating on the Wi-Fi and BLUETOOTH standards can be seen. At the operator's request, some or all devices in the area can be jammed.
The jamming of the Wi-Fi channels is on all technically possible Wi-Fi channels on the both radio frequency bands at 2.4 GHz and 5 GHz. The jamming can be targeted and in total.
1. Targeted (selective)- by jamming signal to selected devices identified by their MAC address. If the target is a Wi-Fi networking base station than all devices (clients) connected to it will be with no Wi-Fi connection.
If the jamming is targeted to a specific client than only the Wi-Fi communication of client will be disturbed.
The targeting is manual by the operator or automatically by predefined parameters.
2. Total jamming - by consequently applying a jamming signal to all available Wi-Fi channels. In this case, the communication of all Wi-Fi devices will be disturbed.
The same is with the BLUETOOTH.
Jamming range outdoors- aprox. 50 m.
The Antenna blocks used for the jamming are controlled by the BLS WI-FI SCREEN PRO System’s computer.
