RJ45 Digital Remote Control Signal Jammer Low Electromagnetic
Radiation
Signal Jammer Description:
Wireless Control System: Jail Jammer System Software
1) Each unit have a control I/O Board (RF module) with hard relays
(for alarm trigger) via wireless output for data transmission to
control of all functions of each unit.- to be controlled via
software program on remote PC workstation by wireless
2) Each Unit be able to send Alert to the remote control PC
workstation by wireless, if any of the RF frequency bands fails
individually from each of the units (VSWR Alarm: Antennas Lost
Connection, Module Failure)
3) All units have individual digital ID to identify them through
the PC workstation.
4) The wireless data will travel to converter in main office and
then convert to RJ45 so it can then communicates with a PC
workstation computer.
5) Prison Jamming system The software can Turn On/Off, each band,
each jammer or the whole jammer system
6) Jammer Unit housing unit is waterproof and heat sink
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.
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".

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:
- High-power multi-band jammer, make high jamming range
- Modular construction for easy maintenance, repair and upgrade.
- Max 300watts total RF output power.
- Special additional housing for all weather protection.
- The general design of the system meets military requirements.
- Different frequency band can be controlled independently by single
switches;
- Power Amplifiers protection design ensures the working reliability
of the device.
- (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 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.
Signal JammerApplication
