　　Because the company's employees play mobile phones during working hours, which seriously affects work efficiency, I want to install signal jammer gps in the office to prevent employees from playing mobile phones during working hours, but I am worried that installing mobile phone jammers in the office will affect the office of the company on other floors.

Will cell phone jammer affect other floors

　　When the mobile phone is working, it is within a certain frequency range. The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. The cell phone signal jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as searching the network, no signal on the mobile phone, no service system, etc.

　　We can find from the installation and operation manual of the mobile phone signal jammer that the shielding effect of the mobile phone signal jammer is mainly affected by three aspects: the power of the jammer itself, the distance from the nearby signal base station and whether there are obstacles. Like general low-power signal shields, there are certain requirements for the installation height, because if the installation is not correct, the transmit power will be weakened by some obstructions, thus affecting the shielding effect. Moreover, most mobile phone signal jammers are not recommended to be used through walls, because after passing through a layer of cement wall, the shielding effect will be greatly reduced. The reinforced concrete structure between floors has a stronger weakening effect on the signal, so the impact on other floors will be small.

　　If you are still worried, you can use a directional mobile phone signal blocker

　　Effectively block GSM/DCS/CDMA/PHS/3G (TD-SCDMA/ CDMA2000/WCDMA)/4G/5G mobile phone signals and WIFI wireless signals within a radius of 1-30 meters, so that the mobile phone cannot make and answer calls, and WIFI cannot work normally , but it will not interfere with the work of other electronic teaching equipment, and the mobile phone can be restored to normal use after leaving the isolation range. It only has a shielding effect on the mobile phone signal on the transmitting surface, and will not disturb other directions.
