What can a signal jammer do?
A signal jammer is an electronic device used to interfere, block or shield wireless communication signals, such as mobile phone signals, WiFi signals, GPS signals, Bluetooth signals, etc. The signal jammer emits electromagnetic interference signals of a specific frequency to interfere or conflict with the target signal, so that the target device cannot communicate normally.
Here are some situations where signal jammers are used:
Prevents eavesdropping, listening and recording: Frequency jammers prevent others from eavesdropping, listening to or recording your communications via cell phones or other wireless devices.
Prevent bomb remote control: In some special occasions, such as government agencies, military, police, airports, railway stations and other places, signal blockers can prevent bombs or other dangerous objects from detonating remotely through wireless signals.
Prevent cheating: In exams or competitions, in order to prevent candidates or contestants from using mobile phones or other wireless devices to cheat, signal jammers can block wireless signals.
Confidentiality: In business negotiations, political meetings, sensitive affairs and other occasions, in order to protect the confidential information of individuals or organizations, signal jammers can shield wireless signals.
What are the different options for the price and use of signal jammers?
The price and usage of signal jammers vary widely by device type and skill level, but here are some common options:
Handheld signal jammer is a portable device, usually used to shield cell phone signal, WiFi signal and GPS signal, etc. They usually cost tens to hundreds of dollars and are relatively simple to use, requiring only the flip of a switch to start interfering.
Vehicle signal jammers are usually used to shield mobile phone signals, WiFi signals, and GPS signals in vehicles. They typically cost anywhere from a few hundred to thousands of dollars and are relatively simple to use, requiring only the device to be connected to the vehicle's power source to start interfering.
Fixed signal jammers are usually used to block WiFi signals, GPS signals and other wireless signals in fixed places. Their prices usually range from several thousand to tens of thousands of dollars, and their use is relatively complicated, requiring professional installation and operation.
Can you recommend a reliable fixed signal jammer?
There are many different types and models of fixed signal jammers available in the market, and it is important to choose a reliable and effective device to meet your specific needs.
When choosing a fixed signal jammer, you can consider the following factors:
Frequency Range: Make sure the jammer covers the specific frequency range you need to block.
Output Power: Select an appropriate output power level to ensure effective signal shielding.
Coverage area: Consider the size of the area you need to cover, and choose the equipment with the appropriate coverage area.
Quality and reliability: Choose equipment from a reputable manufacturer with a proven track record of quality and reliability.
Price: Consider your budget and choose equipment that offers value for money.
