Why can the wireless signal jammer interfere with the normal use of the phone? Mobile phones work by receiving and transmitting radio waves. The frequency of the phone is about 1.8GHz. To interfere with cell phone signals, you must have a device that emits the same frequency of radio waves. GPS Jammer Cell phone signal jammer is such a device, it will block the mobile phone signal within the scope, the degree of light will seriously affect the call and the quality of the Internet. Generally within a radius of 25 meters, the phone will be strongly disturbed by the jammer. The effective range of 25 meters will also be affected less. The scope of the jammer will also change due to the specific performance and power of each jammer.
The portable jammer’s role is to interrupt the communication link (or network) between two (or more) “partners”, when they are trying to talk with each other or deliver certain data between them. Jamming the communication link between a Drone and its Operator is a specific case out of many more; WIFI Jammer we can try to jam the communication between a cellular and the base station, between two tactical radios, between a bomb and a remote control that is used to activate it, etc.
In a press conference on Monday, Stirling said the altercation appeared to stem from gang-related conflict over territory, contraband and cell phones. Stirling said investigators believe cell phones were used by prisoners to communicate about the riot between dorms.Russia’s Rossiyskaya Gazeta daily cited military experts as saying that the Rychag-AV jammers added significantly to reducing the effectiveness of the US air strike on Syria’s Ash Sha’irat airbase in April 2017.
In Russia a lot of the examination room of the university, students through the way of receiving SMS illegally obtaining answers, or simply by taking textbook will answer his accomplices in the examination room the right hand side via their mobile phones to read to them Blog University teachers in Russia say the practice of simply telling students to turn off their phones or to frisk them before they enter the exam has not worked. As such problems become more serious, some of Russia’s higher education institutions have had to turn to the high-tech equipment developed by the elite of the country’s big military companies.

When we enter a new area, the base station in this area will relocate and manage our mobile phone, and the mobile phone will determine its location after receiving the signal from the base station. GPS Jammer If a mobile phone signal shielding device is installed in the area at this time, the frequency band of the broadcast signal sent by the base station will be interfered, and the interference signal will increase the bit error rate of the mobile communication channel and reduce the signal-to-noise ratio of the channel. It affects the effective reception of the signal from the base station by the mobile phone, and the mobile phone will not generate service when the base station cannot be responded to by multiple links.
At this stage, there are many types of mobile cell phone jammer on the market, with different signal strengths, interference frequency bands, and coverage areas. Especially in some “three-no” products, the quality is not smooth, the transmission index value is poor, and the microwave radio frequency module does not press Segment manipulation, the uplink and downlink frequencies are interfered together. Through the specific detection and control of the performance indicators of various mobile phone signal jammers, WIFI Jammer mobile phone jammers can be divided into three categories according to the performance indicators. To tens of meters; the other type is a small output power multi-wireless channel mobile phone signal jammer, the signal strength of the stand-alone version is 5-10 watts, the signal strength of each wireless channel is 1-5 watts, and the shielding range is how many meters to tens of meters; the third The class is high-power or super-power jammers, which are generally dedicated to special industries, such as jammers for public security organs and judicial departments. The output power varies from tens of watts to hundreds of tens of watts, not only for single wireless channels There are multiple wireless channels.

There are many manufacturers of cell phone jammer, but most of them have the same function. The main function is to prevent mobile phones from receiving signals and base stations to send signals, and to shield and monitor mobile phones in specified areas. GPS Jammer The mobile phone signal shielding device can be used in many scenarios, such as bookstores, hospitals, schools, examination rooms, prisons, cinemas, conference rooms, police stations and other places. In recent years, many companies/institutions have installed cell phone signal jammers. Many schools have already installed cell phone signal jammers. The purpose of installing cell phone signal jammers is to provide students with a good learning environment in the classroom. In the past, students played mobile phones, games, sending messages, reading novels, etc. in the classroom.WIFI Jammer It happens all the time, but there is no effective way to stop it. After the mobile phone signal jammer was installed in the back, I rarely saw this happening, which helped the teacher solve a big problem.
That is to say, how long a mobile phone signal jammer can block is not only related to its own signal strength, but also to the distance between the communication base stations in the natural environment of the application (communication base stations are not limited to large and medium-sized signal transmission towers built on the ground). , there are also signal expansion wireless antennas on the roof and some signal expansion and spread in the building), and another key reason is the obstruction, if it is a metal material, it will immediately block; if it is a solid wall of concrete structure, after passing through The loss will be 10 times less; if it is a wood panel, the loss after transmission of the laminated glass material may be smaller. Therefore, the next time a customer asks how long the interference distance is, it is necessary to ask the distance between the communication base stations in the natural environment, and then whether the room is still used outdoors or not, whether to go over the wall or not.Blog Customers can leave a message online to Guanyu Electronic Devices to master the application method of signal jammers. Only by understanding this, can we choose a suitable mobile phone signal jammer for customers.
