To combat the illegal use of mobile phone devices in prisons and government offices, there is a solution that blocks or jams cell phone communication signals: cell phone signal blockers, also known as jammers.

 Today we will talk in more detail about the wifi blocker device, as well as cellular jammers.

 Television, radio, and mobile telephony wireless communications services, among other things, rely on the transmission and reception of waves that traverse the radio spectrum to send information from a transmitting/receiving station to a user device.

 In addition, in order for the electromagnetic waves of the transmitting stations to perceptibly reach the coverage area, or for the signals of user devices to be perceived by the specified area, it is important that each connection passes through the frequency band within the special areas.

 Cellular mobile networks

 In the case of cellular networks, they use radio-electric waves to enable communication between users regardless of coverage area.

 Similarly, to ensure that communications on a cellular network pass through free bandwidth, the technologies used must operate with different time slots, different frequencies, or different codes that identify each link (or combination of them), allowing voice and transmission services to  data that will be offered anywhere within network coverage, even on the go.

 In order for communication services in a cellular network to be successful, in addition to the systems used, they must be able to support the amount of traffic required by users, the spectrum in the communication signals must be free from external interference.

 Factors Limiting Cellular Mobile Network Communication

 In addition to non-technical factors that create typical problems in mobile cellular networks and limit call establishment and access to data services (user credit, device mishandling, etc.), there are technical factors that are inherent to the network.  Components:

 * Technical faults in components

 * Overload of network resources

 * High interference

 Summing up, we can say that jammers are used for different purposes.  Someone uses them at their enterprises, and someone in the theater so as not to interrupt the acting.  This depends on the characteristics of the device.
