Everyone has a general understanding of blocking. We generally know that mobile phone signal blocking can affect the data signal and prevent students from cheating in the exam room.

Yes, the type of signal shielding is unclear.

Mobile phone signal shielding is divided into built-in wireless antenna shielding and external wireless antenna shielding according to appearance. The shield of the external wireless antenna is a plastic casing, and the built-in wireless antenna is a plastic casing.

The application area can be divided into low output power shielding and high power shielding. If used outdoors, it is recommended to use high-power signal shielding.

The principle of cell phone signal jammer is to forward the low-end rate of the wireless channel to the high-end scanner at a certain rate during the working process. These scanner speeds can produce code errors when the phone receives a signal.

Due to the confusion, the mobile phone cannot detect any normal data transmitted from the base station, which makes the mobile phone unable to connect to the base station, thus achieving the purpose of blocking the signal. The main performance on the mobile phone is searching the network, no signal, no signal.

Generally speaking, blocking the outgoing frequency during operation affects the normal frequency of the mobile phone receiving the base station, making the mobile phone unable to connect to the base station, and thus unable to receive calls, receive text messages, and access the Internet normally. When the signal shielding on the mobile phone is turned on, although the mobile phone signal will be full, the signal is not actually bad during use.

When the signal shielding on the mobile phone is turned on, it only has the blocking effect on the mobile phone and has no effect on other electronic products. This is because the signal on the mobile phone blocks the electromagnetic induction signal outgoing from it.

In the collection frequency band specified by the state, only mobile phone communications can be blocked. The moon signal is always in a relatively static state, making it difficult to produce any electronic products.

Cell phone signal shielding can not only be used in school examination rooms, but also in information security conference halls, jail cells, military and other places. In particular, cells must be configured to be shielded to prevent crimes.

People who have contact with the outside world are not allowed to use mobile phones. If signal blocker for sale is used in prisons, it is recommended that high-power signal shielding be used together. In busy situations, small output power can be used to shield, and in large-scale areas, high power can be used to shield.
