What does Jammer mean?
Jammers are usually undetectable, and users may experience minimal effects such as poor signal reception. Jamming devices may be used in any location but are typically deployed where cellphone use may be disruptive, such as in libraries and restaurants. The phone will not be able to connect at this time
How to work the cellphone jammers?
A working cellphone must be in constant communication with its network provider via a cell tower or base station. By sending out radio waves in cellphone frequencies, GSM jammers launch denial-of-service attacks (DoS), causing mobile devices to lose base station communication.
A cell phone jammer is a device that blocks transmission or reception of signals, usually by creating some form of interference at the same frequency ranges that cell phones use. As a result, a cell phone user will either lose the signal or experience a significant loss of signal quality. At this point your phone will display no signal.
Mobile phone jammers can interfere with WiFi, CDMA, GSM, DCS / PCS, 3G signals. The perfect multi-function WiFi jammer, depending on the signal strength in your area. The blocking range is up to 15 meters. The WiFi signal blocker design is really great. There is a cooling fan inside. We can guarantee good conditions of use. Using the Wi-Fi signal jammer, you can stay away from the noise and quiet environment of mobile phone calls, and the mobile phone signal jammer can prevent tracking. You can also protect the network security. You can also prevent others from using it. You can use mobile jammers in many other areas and places.
Why needs to use?
Signal jammers can interfere with mobile phone signals such as conference rooms and test rooms. In order to avoid the influence of mobile phone communication in meetings and tests, and to prevent information leakage and test fraud, wireless signal jammers have become a popular tool. The existing signal shielding device mainly controls the interference switch manually. This program cannot be set automatically. High working intensity. Inconvenient to use. The shielding equipment has no monitoring equipment. We cannot fix it in time. Excessive temperature of the jammer will cause circuit damage.
Cell phone jammers have both benign and malicious uses. Police and the military often use them to limit or disrupt communications during hostage situations, bomb threats or when military action is underway. Portable personal jammers are available to enable their owners to stop others in their immediate vicinity (up to 60-80 feet away) from using cell phones.
Similar equipment is manufactured to block signals in environments where cell phone activity may not be desirable, such as theaters, churches and operating rooms.
To put it simply, a Jammer is, fundamentally, a signal blocking device, which transmits synchronized radio waves on the same frequency range of the device that one needs to blur, therefore preventing devices from transmitting data in the chosen area.
