A GSM jammer is a device that blocks the mobile operator's transmitter from reaching the environment at a certain distance. That is to say, the GSM jammer operates only on the GSM band of the target area. As part of the wireless alarm system, the alert dialer immediately sends a warning signal to the homeowner's previously indicated phone number for protection. Therefore, the purpose of the GSM scrambler is to prevent the telephone transmitter from transmitting these signals to the recipient.
GSM jammers can be placed in pockets for between tens and hundreds of dollars. We can easily purchase the various models we need on the Internet. For individuals, this device is regulated and It is not that it is prohibited in the United States, and we must not use it illegally when purchasing.
The GSM scrambler or jammer GSM only hides the GSM band, so other electronic devices within its interference range are not affected, such as factory devices. In some doctor's offices, theaters or other public places, a sign is usually displayed: please do not use the phone indoors. In some military fields, such as prisons, GSM jammers are used in large quantities and have been authorized.
A small number of thieves often use GSM jammers to eliminate GSM alarms. Therefore, the immobilizer uses a GSM jammer to prevent an alert from being sent over the phone. In addition, thieves can also cut off the phone line to ensure that the alarm is disabled.
