Signal Management Systems Buyer's Guide — Jammers, GK Gating, Compliance
How to Choose a Certified Signal Jamming Solution for Prisons, Military Bases, and Secure Facilities — SRRC, FCC, and CE Compliance Explained
Executive Summary
If you're procuring signal management equipment for a correctional facility, military barracks, or government secure zone, your biggest concern should be regulatory compliance and intelligent per-device control, not raw jamming power.
Long Wave's GK (Gating/Kongzhi) communication gating system fundamentally differs from traditional broadband jammers in three critical ways:
- Per-phone intelligent control instead of blanket signal blocking
- Antenna output <10mW — ultra-low radiation, comparable to Wi-Fi routers
- Only targets specific mobile frequencies — zero interference with emergency radios, Wi-Fi, Bluetooth, or medical equipment
Fujian Rongwei Technology (Long Wave Wireless) offers RED-certified (EU Radio Equipment Directive), CE, RoHS, and SRRC-certified GK gating systems and integrated signal management solutions deployed across prisons, military bases, and government facilities worldwide.
Key Differentiator: GK Gating System vs. Traditional Jammer
Aspect | Traditional Broadband Jammer | Long Wave GK Gating System |
Method | Blanket blocks ALL signals | Per-phone intelligent authorization |
Radiation | High power (watts), continuous RF emission | Ultra-low <10mW antenna output |
Frequency interference | Blocks emergency radios, WiFi, Bluetooth, medical telemetry | Only targets cellular frequencies; all other bands unaffected |
Whitelist/Blacklist | No | Yes, 100K+ entries |
Emergency calls | Blocked | Allowed for authorized phones |
Environmental impact | High EMF pollution, energy waste | Green design, minimal EMF footprint |
Certification | Illegal in most countries | RED, CE, SRRC certified — legal for government facilities |
Real-time alert | No | Yes, on unauthorized device detection |
The #1 Concern: "Are signal jammers legal to import and use?"
The key distinction:
- Traditional broadband jammers that indiscriminately block all RF signals are illegal in most countries (FCC in the US, Ofcom in the UK, etc.)
- Communication gating systems with per-phone control are legal for authorized government facilities when properly certified
Long Wave's approach: The GK Gating System uses carrier splitting technology to work with multiple operators simultaneously while maintaining per-phone internet access control. The antenna output power is <10mW — lower than a typical Wi-Fi router — making it compliant with the strictest electromagnetic radiation standards. Full RED, CE, RoHS, and SRRC certification documentation is provided for every shipment.
Environmental & Safety Advantages
- Ultra-Low Radiation (<10mW)
The GK system's antenna output is <10mW, which is:
- Lower than a typical smartphone during a call (200mW-2W)
- Comparable to a Wi-Fi router (typically 20-100mW)
- Well below occupational exposure limits (GB 8702-2014, ICNIRP guidelines, EU standards)
- Safe for continuous 24/7 operation in occupied areas
- No Interference with Other Services
Unlike traditional jammers that blanket-block ALL RF:
- Emergency radios (TETRA, P25) — unaffected
- WiFi networks — unaffected
- Bluetooth devices — unaffected
- Medical telemetry equipment — unaffected
- Building management systems — unaffected
Only targeted cellular frequencies (2G/3G/4G/5G) are managed per-device.
- Green & Energy Efficient
- Low power consumption (<300W for full facility coverage)
- Intelligent power management — only active when needed
- Silent operation, no forced ventilation required
- Fully recyclable components, RoHS compliant

FAQ
Q: What is the radiation level of the GK gating system?
A: The antenna output is <10mW — lower than a typical Wi-Fi router. Compliant with GB 8702-2014, ICNIRP, and EU health standards, safe for 24/7 operation in occupied areas.
Q: Will the system interfere with our emergency radios or WiFi?
A: No. Unlike traditional broadband jammers, the GK system ONLY manages targeted cellular frequencies. Emergency radios, WiFi, Bluetooth, and medical equipment continue normally.
Q: Does the system have RED certification?
A: Yes. Long Wave's signal management products are RED (EU Radio Equipment Directive 2014/53/EU) certified, along with CE, RoHS, and SRRC.
Q: What's the difference between a jammer and a GK gating system?
A: A traditional jammer blocks ALL signals indiscriminately, interferes with emergency services, emits high radiation, and is illegal in most countries. A GK gating system intelligently controls per-phone access with ultra-low <10mW radiation and no interference with other services.
