Selective Jammer

What's a

Selective Jammer

A selective jammer is a system that allows whitelisted phones to access public networks while jamming all other devices.

- Prevent unauthorized network access

- Identify illegal or hidden cellular devices

- Block data transmission of eavesdropping devices using SIM/eSIM cards

Enhanced Security

- Allows specific control over network access in different environments

- Jamming radius adjusted

Reduced Interference

BENEFITS

- Only jam unauthorized devices while allowing legitimate use

- Software defined to adapt to public network change

- Time-scheduled on/off

Flexibility

Benefits of a Selective Jammer

IMSI READING

Signal Detection and Identification

The smart jammer scans for nearby mobile devices and reads their IMSIs (International Mobile Subscriber Identities) when they attempt to connect to the network.
IMSI FILTERING

IMSI-based Whitelist and Blacklist Filtering

The jammer compares the detected IMSIs with pre-configured whitelists (allowed devices) and blacklists (blocked devices). Devices on the whitelist are allowed to connect to public networks, while those not listed are jammed.
DISTANCE CONTROL

Jamming Distance Adjustable

The effective jamming range can vary depending on the jammer’s power, but the radius is typically adjustable, allowing control over how far the jamming signal extends.

SECURITY MONITORING

Persistent Monitoring of Potential Security Threats

1. Persistent monitoring of unauthorized or suspicious devices and identifying intruders.

2. Alert security when an unregistered or suspicious device is detected.

3. Block data transmission of eavesdropping devices with SIM/eSIM card.
