Description

Base structure for shielding device and shielding device

Technical Field

The utility model relates to the technical field of shielding devices, in particular to a base structure for a shielding device and the shielding device.

Background

The signal shielding device mainly adopts fixed site installation (wall-mounted or floor-mounted), vehicle-mounted or backpack design and scans from the low end frequency to the high end of a forward channel at a certain speed aiming at various places where mobile phones are forbidden, such as examination rooms, schools, gas stations, prisons, secret places, military bases and the like. The scanning speed can form disorder code interference in a message signal received by the mobile phone, and the mobile phone cannot detect normal data sent from the base station, so that the mobile phone cannot establish connection with the base station, and the phenomena of no signal, no service system and the like are presented.

The power of the current shielding device is generally 12W to 480W, and the high-power signal shielding device adopted for special areas such as prisons, military bases and the like is required to have large coverage range, and overlapping areas are arranged between the mutually covered areas so as to avoid shielding gaps.

It can be seen that, with the development of communication, the frequency bands of signals are more and more, when people wish to shield signals in all frequency bands, the more antennas are needed, and the current shielding devices are all of an integrated structure, so that only more shielding devices in the frequency bands can be purchased again, and the defects of fast iteration and high cost are caused.
