5 Signal Jammers You Need to Read

　　Types of common jammers on the market

　　Mobile communication jammers

　　Mobile Communications Gambler offers to block the GSM 900-1800 network, which makes it possible to completely destroy cellular phone signals within its working range. The phone will not be able to transmit messages and make calls. Cell phones are not only used for communication, but also for eavesdropping, so the GSM signal jammer, which locks eavesdropping with the help of this device at the meeting.

　　Common cell phone signal jammers misunderstandings

　　Common GPS jammers misunderstandings:

　　① The bigger the jammers power, the better

　　1. The host frequency output is inaccurate, the frequency drifts, the bandwidth is too wide, the power is wasted, and the interference base station;

　　2. The shielding efficiency of the simple frequency sweeping power suppression method is not high, and the radiation is large;

　　3. Power false standard, exaggerated propaganda, the nominal power loses its reference value;

　　4. Power is the foundation, and technology is the shutdown. It is better to find good methods and techniques than to fight for power recklessly;

　　In-depth analysis of signal jammers

　　Although a mobile phone is a wireless communication device used wherever it goes, there is also an invisible line that drags it, that is, the mobile phone base station. Whether a mobile phone makes or receives a call, the first step is to establish a connection with a nearby mobile phone base station. If you hold a mobile phone in your left hand and your right hand, and use the left-hand mobile phone to dial the right-hand mobile phone, the electromagnetic waves of the mobile phone are not transmitted directly from the left hand to the right hand, but will be transmitted from the left-hand mobile phone to hundreds of meters away The mobile phone base station, and then make a big circle to transmit back to the right mobile phone.

　　Normally, the radio wave signals sent by the base station and the mobile phone come and go, but once the shield is opened, it will cause interference around the mobile phone, and emit a "noise" radio wave signal that is many times more powerful than the received base station signal. If you can't hear what the base station is talking about, you can't receive the base station's signal normally, and the connection between the two is cut off, and the mobile phone will become an jammers gps.

　　Cell Phone Jammer parts to Know

　　Cell phone jammers are like cell phones in that they differ by make and model. Some rely on a simple switch while advanced models require a manual change in frequency.

　　While every model is different, there are some universal parts to cell phone jamming devices.

　　The most important parts to know are the components of the RF section. This is the most pivotal part of the device because it communicates with the cell phone.

　　The first part of the RF section is the antenna. This is what sends the signal out into the world.

　　Determine The Jammers Range

　　If you couldn’t find the jammer’s range on the specifications, or you didn’t check before buying, you should determine it in a different way. You can:

　　Test the device’s range manually by walking away from the device with your own cell phone and checking signal bars

　　Look at the output power and compare it to the cell signal in the area

　　Amoderate level of cell signal can be blocked by a jamming device with 1W output power within 10-30 meters. Use this example as a base for determining your range.

　　Think back to when you first scanned the area.
