Product Description

Introduction to the Equipment

The WiFi wireless network detection analyzer is a device designed for conducting wireless signal analysis and precise positioning of WiFi terminal devices such as mobile phones, computers, and wireless cameras. By receiving wireless signals emitted by wireless terminals like  mobile  phones  during  communication  with  wireless  access  points,  the  device demodulates  and  analyzes  the  target   signals,  thus   analyzing  and  summarizing  the surrounding wireless signals. Additionally, it can precisely locate the target by measuring the wireless signal strength of both the WiFi terminal and the wireless hotspot. The analyzer also supports interfering with and counteracting the target wireless signal, hindering its normal network activities.

The WiFi wireless network detection analyzer is capable of accurately analyzing, within a large area, the wireless network names (SSID), MAC addresses of devices, wireless channels, encryption  methods, wireless  signal strength  (RSSI),  and other  relevant  information  of hidden and open wireless  hotspots and wireless terminal devices  in the space.  It  also possesses functions  such  as  precise  positioning,  searching,  and  blocking  control.  The analyzer boasts high capture rate, effective management and control, and high positioning accuracy.

The WiFi wireless network detection analyzer is widely used in technical reconnaissance departments of public security, national security, confidential departments, security bureaus, and national institutions for wireless network detection and analysis.

Equipment Functions

The equipment supports scanning of hotspots and terminals operating on 2.4G, 5.2G, and 5.8G frequency bands.  It also supports scanning of devices with WiFi enabled but not connected to any network. It can detect the activity level of targets (hotspot detection supports  various  WiFi  routers,  AP  access  points,  portable  WiFi  access  points,  printer hotspots, soft APs, and mobile phone hotspots, while terminal detection supports various WiFi terminals, desktop computers, laptops, tablets, mobile phones, smart home devices, WiFi cameras, etc.).

The WiFi wireless network detection analyzer adopts an integrated design in hardware, equipped with four high-gain omnidirectional antennas that can scan indoor targets. It can also  use  an  external  directional  antenna  for  large-scale  scanning,  and  better  target positioning  can  be  achieved  through  the  directional  characteristics  of the  positioning antenna.

The software is equipped with the latest WIFI wireless analysis and positioning system, supporting wireless frequency bands: 2.4G, 5.2G, 5.8G, and wireless channels: 2.4G: 1-13, 5.G: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140. It can simultaneously track signals from multiple channels and multiple targets. A unique signal tracking algorithm is adopted, significantly improving the ability to accurately locate targets. At the same time, the equipment supports activation measures for target terminals with small  data volumes,  optimizing  the  situation  where  target wireless  signals  cannot  be captured for a long time when the target is silent.
