Technical Differences: Signaling Jammer vs Traditional Jammer

## What is a Signaling Jammer? A signaling jammer is a next-generation signal shielding device based on SDR (Software Defined Radio) architecture, fundamentally different from traditional noise-based jammers. ### How Traditional Jammers Work Traditional jammers emit wide-band noise signals to "drown out" normal communication signals: - **Small coverage radius**: Requires high power - **Interferes with base stations**: Uplink signals may interfere nearby - **High power consumption**: Continuous noise emission ### How Signaling Jammers Work Signaling jammers analyze base station downlink signaling and send specific "pseudo-base station" signals to terminals, causing phones to actively disconnect. **Advantages**: 1. **Single channel power < 2W**, much lower than traditional 2. **Zero base station interference**, only blocks terminal downlink 3. **Blocking rate > 99%**, precise and controllable 4. **TDD synchronization**, aligned with base station time slots ### Technical Comparison | Parameter | Traditional Jammer | Signaling Jammer | |-----------|-------------------|------------------| | Single channel power | 5-10W | < 2W | | Coverage radius | 15-20m | 10-15m | | Base station interference | Yes | None | | Blocking rate | 80-90% | > 99% | | Power consumption | 200-500W | < 160W | ### Importance of SRRC Certification According to China's radio management regulations, signal shielding devices must obtain SRRC (State Radio Regulatory Commission) type approval certification. Uncertified devices are illegal to use. Pinbi Filter's signaling jammers have obtained SRRC certification, legal and compliant for various exam venues.
