There are many names for 5G signal jammers, such as signal jammer, mobile phone shielding, signal interference, data signal influencer, data signal shielding, mobile communication technology signal interference, data signal shielding, cell phone signal jammer, signal shielding, and wireless communication signal shielding.

For the upper and lower security channels of the mobile phone system, technologies such as memory overclocking, frequency division, and frequency hopping filtering are used to analyze the necessary shielding frequency; a spherical shielding indoor space is formulated according to the signal shielding output power, and shielding will be automatically generated within the specified range. Electromagnetic fields make mobile phones ineffective in indoor spaces. When the signal shielding is in operation, the data signals sent and received by mobile phones within a specific range are invalid, which means that the phone cannot make calls and receive calls, thus achieving the purpose of forcibly prohibiting use.

The working principle of 5G signal jammer: Within a certain frequency range, mobile phones and communication base stations are connected to each other based on electromagnetic waves, and adopt a certain serial baud rate and configuration method to transmit data information and sound.

The shielding range of the 5G jammer is based on the output power of the signal jammer. During on-site testing, the high and low shielding ranges of signals in the local environment are different. For example, if the indoor signal has a weak shielding range and a large range, a GSM base station should be equipped outdoors, so the GSM signal is close to the outdoor shielding range.
