WS-500 is specialized equipment designed for police and national security services. Its purpose is to disable illegally deployed active intercept systems in a given area.
Design and Power
- Available in two formats: a rugged medium-sized case or a 19-inch blade.
- Can be powered by mains electricity, a vehicle power source, or internal batteries.
- Battery operation supports at least 3 hours of continuous use.
Subsystems
WS-500 has two main components:
1. Detection module
2. Jamming module
Operation
- Once activated, the system scans the radio frequency (RF) environment.
- It identifies active intercept systems by analyzing multiple parameters.
- The WS-500 captures information from the downlink channels of the target system.
- Using this data, it jams the uplink channels, blocking communication between the intercept system and its target cellphones.
- Typically, the operator of the intercept system cannot detect the cause of the failure.
Adaptive Jamming
- If the intercept system switches to different frequency channels, the WS-500 automatically repeats the jamming process on the new uplink frequencies.
- Because uplink and downlink frequencies are duplex-separated, the WS-500 can detect and jam simultaneously.
Multi-Band Use
- To jam both European and US GSM bands, two WS-500 units are required.
- The detection and jamming modules must be placed at least 50 meters apart.
