Why install a cell phone signal jamger in prison?

 Under normal circumstances, there are several models of high-power mobile phone signal shielding devices. The high-power mobile phone signal shielding device makes the chip the same as the retail repeater or base station on the market. In theory, the radiation of the high-power power amplifier chip Larger, and secondly because the shielding radius is too large, it will affect the place that should not be shielded.

Mobile phone signal shielding devices are generally used more in the field of prisons or detention centers. This is because the shielding range of mobile phone signal shielding devices is large, the installation is gradual, and the number of installations is small, which is very popular among customers. However, in the high walls of the prison, the shielding band will also be affected by the density of the building and the wall of the building, thus leaving a blind spot for shielding. Therefore, in the prison, it is also recommended to use the cell phone signal shielding device of the size and power together. Use a low-power cell phone signal blocker when shielding blind spots, so that the problem of shielding blind spots can be solved.

When the mobile phone signal shielding device is in use, it will not interfere with the operation of other electronic devices. This is because the electromagnetic signal emitted by the mobile phone signal shielding device is completely within the collection working band specified by the state, and only the mobile phone communication is blocked. effect. And this signal is always in a relatively static state, and will not affect any electronic equipment.

In the scope of cell phone signal shielding, although some mobile phone signals will be full, but in fact, there will be no signal when using, the mobile phone is a small brick.
