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

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
  1. 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
  1. 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.
  1. 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.
