multifunctional wireless jammer

Multifunctional wireless signal jammer is a new high-tech information security product developed by comprehensive comparison of electromagnetic emission suppression methods. An electromagnetic protective field is formed in places where the use of wireless communication equipment is prohibited.

When the wireless signal jammer is working, some mobile phones will still have a signal, but this is a false signal and it is impossible to communicate.

The electromagnetic signal emitted by the wireless signal jammer only has a blocking effect on the wireless communication signal in the shielding place, and this signal is always in a relatively static state and will not affect other electronic equipment.

The electromagnetic signal intensity emitted by the wireless signal jammer is very weak and will not cause harm to the human body. It will only block the connection between the mobile phone and the base station.

Wireless signal jammers generally have an outdoor signal greater than an indoor signal, so the outdoor shielding effect is poor.

There is a cooling fan on the back of the wireless signal jammer, so the machine will not be damaged even if it works for a long time. It uses the thermal conductivity of aluminum alloy high-performance heat sinks to dissipate the heat generated when the machine is working. So as to ensure that the machine works stably for a long time.
