Digital Cell Phone Signal Jamming Device , Cell Signal Scrambler VSWR Protection​

How do inmates get their hands on cell phones? Apparently, visitors and corrupt prison guards have been known to furnish these phones to inmates. To help combat this phenomenon, several states have attempted to crack down by making the repercussions more serious. Courts have allowed punishments for those found with a cell phone on the basis that these conversations cannot be monitored and are thus a security threat . Several states have made it a crime for a prisoner to have a cell phone, and some are looking to raise that crime to the level of felony .

Unfortunately for prisons, Prison Jamming system cell phone jamming (interfering with radio waves to block cell phone communication) is not a viable option — at least not in the U.S., where cell phone jamming devices are illegal as a result of property laws. In addition, even if prisons got permission to jam cell phone signals, the jammers could also interrupt the prison’s radio signals Despite these concerns, jails in other countries, such as England, have implemented jammers because of the prevalence of cell phones.

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".

Signal Jammer Technical Specification.

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.

Signal 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.

Signal 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.
