Product Details
Product Features
The prison signal jamming system is a frequency suppression device built with digital synthesis technology. It blocks RF signals such as CDMA, GSM, DCS, LTE, Wi-Fi, walkie-talkies and GPS, and covers the frequency band from 20 MHz to 6000 MHz.
- Designed to block GSM, CDMA, LTE and Wi-Fi signals in prisons and other designated areas.
- Features long effective jamming range, high output power and flexible antenna installation height.
- Multiple jammers can be deployed and centrally managed for full-area coverage.
- Built-in digital synthesis signal source delivers superior jamming performance.
- Supports 24/7 continuous operation under all weather conditions.
- Adopts the latest design with combined heat sink and fan for reliable heat dissipation.
Function
Multi-band Interference
It works on frequencies of 400MHz, 900MHz, 1.5GHz, 2.4GHz and 5.8GHz, covering most UAV, mobile communication and navigation frequency bands.
Will other electronic devices work normally?
Yes. The jammer only transmits signals within government-regulated frequency ranges and merely blocks mobile phone communication. It does not affect other devices.
Is the jammer harmful to human bodies and mobile phones?
The electromagnetic signal intensity fully complies with national electromagnetic wave safety standards. Test results prove its radiation is low and harmless to humans. This device only disrupts signal reception between mobile phones and base stations, and causes no physical damage to the phones.

FAQ
- Q1: How does digital synthesis technology improve interference performance compared to traditional analog VCO jammers?
- A1: Digital synthesis provides highly accurate signal generation and superior frequency stability. This enables precise band targeting with flat spectral power distribution, preventing frequency drift due to temperature swings and delivering significantly more effective suppression against modern agile protocols like LTE and WiFi.
- Q2: Will this high-power jammer cause interference to authorized electronic equipment outside the targeted bands?
- A2: No. The system is engineered to restrict its electromagnetic emissions strictly to the government-regulated communication and cellular frequencies designated for interception. It has no structural or spectral overlap with legal, out-of-band electronics, ensuring they remain fully operational.
- Q3: Is the electromagnetic output of a 700W system harmful to human health or prison staff?
- A3: No. The system’s radiated intensity complies with international and national standards for environmental electromagnetic wave health. The signal acts exclusively to saturate the receiving conditions of target mobile devices rather than destroying components or emitting ionizing radiation, making it completely safe for regular proximity deployment.
- Q4: How does the system handle extreme thermal loads during continuous 24/7 operation?
- A4: Driving 1400W of total power requires rigorous thermal management. The unit integrates a systematic smart cooling system pairing high-surface-area extruded aluminum heat sinks with automated active cooling fans. This configuration maintains safe internal junction temperatures under all outdoor weather environments.
- Q5: Can multiple units be managed simultaneously to cover large correctional facilities with complex terrain?
- A5: Yes. The architecture supports centralized network control, allowing security administrators to deploy multiple jammer nodes across a facility and manage their power levels, channel activations, and system health status from a single unified master console.
