Block Cell Phone Number 2 Degrees

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. Block Cell Phone Number 2 Degrees Communication principle, the jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. This 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 a search network, no signal, no service system and other phenomena. If you dial the phone from the unshielded area to the shielded area, you will often walk into the shielded area for a considerable distance before the mobile phone is completely shielded. This is because once the mobile phone is dialed, the mobile phone itself has the ability to resist interference. This kind of anti-interference will make the mobile phone adjust its transmitting power to ensure the normal call this time. Therefore, it is generally not recommended to perform dynamic testing in the call state, but to perform static testing at various points. cell phone jammer

When the phone battery is activated, it will generate enough energy when it rings. It may cause a fire. The safety-related part prohibits the use of mobile phones at gas stations. The introduction time is long, and the effect is not ideal. The gas station equipment is controlled by a computer. The telephone signal will affect the normal operation of the device. Add Block Cell Phone Number 2 Degrees to gas stations to prevent some tragedies. Relevant departments are proposing to install cell phone jammers at gas stations in their jurisdictions.
