Stop Contraband Digital IED Jammer High Power Prison Jamming System


Prison Jammer Description:

Big Power Prison Jamming system is most important device.

for inmates to dodge prison eavesdropping is to gain their own phones. Prison authorities have found it’s surprisingly easy for prison inmates to get their hands on working cell phones (with chargers to boot). 
Cell phone accessibility has become a serious problem for prisons — in addition to the crimes that inmates are known to commit over the phone. Gangs can organize themselves far more easily when members in prison have cell phones. The gang caused uprisings in more than 70 prisons, and meanwhile, members outside of the prison caused riots and wreaked havoc on public busses and police stations. Gangs transcend prison bars in the U.S., too, where gang leaders have been able to wield their power from inside prison walls — even ordering gang murders.


The Prison Jammer GW-J800DNW manages the problem of illegal cell phones in a Prison or Government facility. Prison Solutions from government stop smuggled phones from making calls by using RF Jammers.

Our solutions are good at operation and design. Prison Jammers work to block off large areas in a building to stop cell phone calls. These Prison Jammers are installed in a pre-determined pattern.

Using digital Gaussian white noise technology for Maximum performance. Will cut-off all Cellular Communication between Mobile Phones and Cellular cells.


The Jamming Radius depends on the strength of the signal in given area. All Cellular Mobile Devices will be totally BLOCKED, and will not be able to receive or dial outgoing calls. the cell phone display will show "NO SERVICE".


Digital noise technology jamming range is very high, 5 times stronger than VCO technology jammer.

Digital Gaussian white noise is essentially a pseudo random signal, signal characteristics consistent with a random function. Strong Anti-interference ability, there is no need high power interference radiation power, influence and damage to the electromagnetic environment is very small, can bear long distance loss. Long-term cases, interference stability. Mechanism causes due to interference, interference by external environment (such as wind, rain, ice, variations on space) change is not obvious.

There are 3 types RF Jammers:
1. VCO(voltage controlled oscillator) Technology
2. DDS (Direct Digital Synthesis)Technology
3. Pseudo random digital Gaussian white noise technology.


General speaking:
1. VCO(voltage controlled oscillator) Technology
Requirements for the jamming range is not high, extremely sensitive civilian consumption levels of low cost, but efficiencies are not very strict scene.
2. DDS (Direct Digital Synthesis)Technology
Requirements for the jammer need wideband frequency range, and choose different frequency range, such as 20-3000MHz NO gap jamming.
3. Pseudo random digital Gaussian white noise technology.
Requirements for the jamming range is very high, can accept high cost, national security and military, have strict requirements for jamming range.



Prison Jammer Features:

  1. High-power multi-band jammer, make high jamming range
  2. Modular construction for easy maintenance, repair and upgrade.
  3. Max 300watts total RF output power.
  4. Special additional housing for all weather protection.
  5. The general design of the system meets military requirements.
  6. Different frequency band can be controlled independently by single switches;
  7. Power Amplifiers protection design ensures the working reliability of the device.
  8. (Optional)Can customize these frequencies AM, FM, VHF, UHF, 450MHz, iDEN, CDMA, GSM, GPRS, DCS, PCS, AWS, WCDMA, LTE 700, LTE 800, LTE 2300, LTE 2600, GPS, WIFI, WIMAX, etc.

Prison Jammer Advantages:
1. VSWR protection,

When there be antenna disconnect, full system will not burn out.
2. Waterproof Level: IP63
Good cooling system, Continuous operation, even in hot climates.
3. Stable capability, cost-effective choice
4. Each channel can be controlled separately and simultaneously.
Manual adjustable output power with each channel.

allow the total blockade without interference of the people who live outside the perimeter of the prison.
5. Remote Monitoring(Optional)
Remote Monitoring available by Ethernet Network
Remote Control Interface: RJ45

Provide a system (software and hardware) that allows the authorities to supervise the operation at 100% of the blocking system.

6. Small influence to the electromagnetic environment.

Comply with the maximum power allowed for non-ionizing radiations that affect the health of people.

Prison Jammer Application:
Prisons, military, government, Oil and Gas Storage Facilities and fields, Churches, Theatres, News Conference Rooms, Libraries, Museums, Courts, Border Patrol and Drug Enforcement, Customs, mosques, etc.
