Where the GPS tracking jammer is located, the GPS receiver does not show any movement signal, so that the navigation function of GPS system fails. The GPS tracking jammer is perfect to jam the L1, L2, L5 civilian GPS signals. The GPS tracking jammer is quite easy to operate. With the antennas, the range of the blocking area can be attuned for the individual needs in the specific conditions.

The next day when they go to clas, they will sleep at the desk. In order to avoid the chating on mobile phone after lights out at night and ensure the good rest, the special devices- cell phone jammer can be installed in the dormitory building. The mobile signal will be shielded after 23:00 everyday. The school can install the fixed phone on each floor of the dormitory building. If the parents need to contact with the students for emergency, they can build the connection conveniently.

The electromagnetic wave is everywhere around us. The TV broadcasting, mobile phone and walkie-talkie will generate the radiation which is difficult to avoid. The electromagnetic radiation influence on people has not been confirmed. But the lower the better to our body. Regardless of the irresistable TV signal in the air, we can start from the mobile phone using.

When you dial the number, you should put it near the earphone after the connection. It's said that when you make a call, the radiation power is strong. So you should get the phone close to your ear after you get through the phone.

When you go to bed, don't put the mobile phone close to body. In theory, people will suffer less for longer distance. As you don't need the mobile phone when you sleep, you can put it away from you.

And we don't need to worry too much abou it.

You can also use the earphone. The earphone distances the head and the antenna and lowers the radiation. If you make a call for a long time, the earphone will ease your muscular fatigue.

Close the message report. The message report looks very convenient. But actually each message report is equal to a message. In order to decrease the radiation generated by the communication, you can close it.

Turn off your mobile phone in the poor signal area. The transmitting power of mobile phone will be automatically increased. And the mobile phone will keep searching the network frequently. If it's unnecessary, you are suggested to turn off the mobile.

Cell Phone Jammer

The arrival of cell phone has caused a revolution in our ways of communication and networking. While it brings convenience to everybody, some sort of discomfort also emerges along the way. Take the two following situations for example, situation 1: you need to have a private conversation with your business partner, it may occur that your rival is stealing your information via your cell phone when you forget to switch it off; situation 2: when you sit an examination that you’ve prepared for a long time, it is very likely that your edge is lost if your phone is not advanced enough, for all the examiners are accessible to sending and receiving messages. If so, perhaps you are desperate for something to block off the signals of the cell phones. That is why cell phone jammer comes into use.

Cell phone jammer is a newly developed electronic product for jamming the transmission or reception of signals. This instrument can provide a signal that emits the signal within the similar frequency range that cell phone utilizes and thus restricts the use of cell phones due to the intervention. The actual range of cell phone jammer is subject to its size and local environment. Generally speaking, the bigger the jammer is, the longer the range it covers. Similarly, a smaller one can cover only a few meters. The environment here refers to the hills or walls that can prevent the jamming signal.

Inside the cell phone jammer are an antenna, circuitry and a power supply. The antenna functions to send the signal. It can be inside the electrical cabinet. On stronger devices, the external antenna can cover longer range and be tuned for individual use. The main electronic components of a jammer are voltage-controlled oscillator and tuning circuit. The former helps to generate the radio signal interrupting the cell phone signal; the latter controls the frequency at which the jammer gives its signal by sending a particular voltage to the oscillator. Most of the cell phone jammers are battery operated. It is essential that the cell phone jammer be charged in time. Undercharged cell phone jammer covers only a limited range, far shorter than its normal state.

Cell phone jammers are often installed where silence is desirable. Offices and companies are the main purchasers of the product. When a meeting is held, a single phone ring will definitely spoil the temperament of the busy and intense environment. Hence when the cell phone jammer is available, no disturbance will be created by the cell phone. Of course, the cell phone jammer system is also welcomed by schools. When cheating in examination are becoming regular, the leakage of questions and answers via cell phone can be avoided through such an equipment.
