一、Phone Jammer Systemr Project In Jails

1.Brief introduction of handset:

Working principle of handset: In certain frequency band, handset connect the base station with radio wave, and transfer data and sound by certain band rate and modulation.

2.Brief introduction of mobile phones jammers:

The jammer scans the forward channel with the certain speed, from low frequency to high. This scanning will create the noise in the TX signal, result that the handset can not receive the signal from the BTS, and disconnect with the BTS. From the handset, you will see Searching\No signal\No service...

3.Main function:

a.Can block CDMA, GSM, PHS, 3G etc. effectively.

b.Only block mobile phone signal, have no influence to any other electronic device.

c.Delay startup design, after connect the power supply, can work stably for a long time.

d. Have only 1/20 of mobile phone radiation, no influence to human body.

二、Summarize

In the information age, communication technology is development at a high speed. Mobile phone is an importment tool in our lifes. But with the widely used of mobile phones, it creats some problems. The main is:

1.1Becomes new channels of reveal the secret, pose a threat to the safe of private information

With the development of high technology, positioning, tracking and surveillance the mobile phone becomes the most importment reconnaissance means and information source all over the world. So taking mobile phone in secret places, no matter use or not use, as long as in the standby state will reveal the secret. It harms to parties and countries.

1.2 Becomes new noise pollution sources, interfering the normal working

With the increasing popularity of mobile phones, the environment used in meeting rooms, court, library and school are worsen, the noises from mobile phones broke the quiet and solemn atmosphere of these places. Affect people’s normal working.

1.3 Becomes new unsafe factors, had hidden danger to safety production of enterprises

Use mobile phone in gas station, oil field and oil depot may lead to fires or explosions, the consequence is very serious.

1.4 Becomes new criminal means, affect social stability

Some opportunistic people use mobile phones for cheating on exams. Some terrorists and hostile element also use mobile phones to detonate bombs.. The fact indicates that the mobile phones has become a tool for criminals in some occasions, brings adverse impact to social stability.Our manufacturerd GSH mobile phone jammer can solve above problems effectively. It as a new information security products, with a specific electromagnetic signals form a network electric fence in some places which need protection, make mobile phone can’t receive data from BTS and establish connect with the BTS. Play a security role, eliminate the adverse impact of the mobile phones.

三、Applications & Features

2.1 Applications

Mobile phone jammer only have an effect on mobile phone communication, not interfere with other electronic equipment, can be widely applied.

2.1.1 All kinds of meeting rooms, auditorium, courts, libraries, examination rooms, schools, movie theaters, hospitals;

2.1.2 Gas stations, oil fields, oil depots;

2.1.3 Government, military, finance, securities, jails, police or command center all places where forbid to use mobile phone.

2.2 Features

2.2.1Our jammer use the most efficient RF chip on the market. The normal chip’s efficiency is only 30-40percent, our chip’s efficiency reaches above 70percent, transform electric energy to most effective power, reduce calories. The technology is currently ahead of peers.

2.2.2Our jammer calculated at minimum efficiency, the effective power is 19W×70%=13.3W, the power of calories transformation is 19W×30%=5.7W. In the same way, the normal jammers’ average effective power is 14W, and the average calories transformation as high as 26W. So our jammer is the most energy-efficient jammer, and have high efficiency, not hot, can live 3 times than our competitors, have only 1/20 of mobile phone radiation, at the same time all of our jammers can block 3G signals!Production process strictly follow the ISO9001 quality system, work stable and reliable, strengthen security of information, ensure safey production and protect the environment, is a ideal and reliable safety product.

四、Main Functions & Technique Data

3.1 Main Functions

3.1.1 Five-channel models, block CDMA, GSM, DCS, PHS, 3G signals

3.1.2 Only block mobile phone signal, have no influence to other electronic equipment

3.1.3 Generally speaking, 200 meters away from the base station can get a good effect

3.1.4 After plug in, can work continuously and stably

3.1.5 Delay startup design can avoid strike fire generated by mechanical switch

3.1.6 Ahead of peers, stabilivolt technology of pressure rise and then drop, completely resolved the problem that the signal excursion in

continuously working status.

3.2 Main Technique Data

3.2.1 Effective shielding radius: 0-70meters (If the mobile signal is strong in the installation site, the shielding effectiveness is bad, vice versa)

3.2.2 Jamming band:

CDMA: 869-894MHzGSM: 925-960MHz

DCS: 1805-1880MHz1900-1990MHz3G: 2110-2170MHz

3.2.3 Working Hours: Work continuously

3.2.4Environment Temperature: -40℃ to +55℃

3.2.5Relative Humidity: 30%--95%

3.2.6Power Adapter: Input AC 160V-240V Output DC5V

五、Installation Project

Have three methods

1.Three-dimensional installation: install every 15-25 meters in the external wall with four sides of East, South, West and North in every builiding in jails. The installation number of each floor decide to the length and width of the floor, below 3 layers. If above 3 layers, the method is the same, but the installation number will be increased appropriately. Because it is intalled in the external wall, it is necessary to do a good waterproofing measures. GS-08 mobile phone jammer have waterproof and anti-damage functions. The method of construction is too much trouble, but ithas a good effect, and save money.

2.Indoor installation

Install each housemaster, the method is easy to install, but need large numbers and cost too much, have a good effect.

3.Corridor installation

Install every 10-15meters each corridor in each building, the installation numbers decide to the length of corridors. The method has to increase the numbers of jammers to achieve the effect, easy to construction. The deficiency is install large numbers. During the installation should pay attention to: The first is that the antenna should pointed to the open area (the antenna is best not to move towards the ceiling or other obstacles, at the same time, the antenna can also be 90 degrees bending); The second is that the power supply (with Host) is best far away from the Host; The third is that the antenna of the Host is best have no AC line through; The ast is that if install not in one layer but in the second layer, the antenna must be down.
