SEA 3809E WLAN Scanner

Fast acquisition of WLAN signals

With the SEA 3809E WLAN scanner, a universal device is available to easily detect existing WLAN access points or the propagation of signals. For this purpose, the current GPS position is recorded together with the captured channel information and signal levels.
The highly sensitive RF sensors for the WLAN frequencies 2.4 GHz and 5 GHz reliably receive even very weak signal levels. The metadata of hidden networks such as access points, unknown WLAN devices such as smartphones or smart home devices are securely captured and recorded. Multiple RF sensors, which can be configured for different WLAN technologies and channels, thereby capture many signals simultaneously.

Typical application areas of the WLAN Scanner

  • Recording and capturing access points and metadata of connected devices
  • Range testing and surveying of terrains and buildings
  • Association of WLAN devices to WLAN access points
  • Recording of probe requests and WLAN beacons
  • Recording of PCAP data (WLAN only)
  • Reception of Bluetooth Classic/BLE metadata
  • Localization of WLAN access points
  • Monitoring tasks, e.g., in meeting rooms with alarm function

Indoor detection

Indoor software plugin

An indoor software plugin (as of Q3/2023) is available for indoor recording to get an overview of WLAN coverage even in large properties such as shopping malls and airports.

Evaluation software SpaceMaster for WLAN evaluation

with extensive evaluation & analysis functions

For the evaluation of extensive measurement data, the SpaceMaster® evaluation platform is also available for management, visualization, and analysis.
The measurement data of the devices can be automatically transferred and read into the system via built-in mobile modems. Here, the recorded measurement data can not only be permanently stored, but also filtered according to any criteria, evaluated and displayed in maps. The acquired WLAN metadata can be visualized with extensive filters, e.g., according to radio standard, technology or also reception quality. Extensive evaluation, reporting, and export functions enable the targeted highlighting of radio cells or the visualization of intersections or overlapping areas.
The software supports the simultaneous visualization of classic mobile radio cells, WLAN access points or, e.g., Bluetooth beacons. Available mobile radio technologies such as 2G, 3G, 4G are supported as well as the new standards 5G or applications in the NB-IoT and LTE-M band.
