From the perspective of shielding area, the mobile phone shielding scheme in the conference room is recommended

When designing the shielding scheme for conference mobile phones, many purchasing units are not very familiar with some important elements of shielding. In particular, they are at a loss about the highly professional words such as the signal strength of the base station. This also leads to the integrator not knowing how to start when designing or recommending the scheme. From the perspective of shielding area, this paper provides some other ideas for the design of mobile phone shielding scheme in conference room.

1、 Small conference room mobile phone shielding scheme (20 ~ 50 m2)

1.1 scene features: the number of meeting rooms is small and scattered, and there is no signal amplifier in the room.

1.2 basic shielding mode of mobile phone shielding in conference room (2G ~ 5g \ WiFi)

The portable intelligent small power shield bls-350dzq (which can be fixed or freely supported by the bracket, which is an upgraded version of bls-350dzi) is used. When using, take out the equipment and place it on the supported bracket (which can also be directly placed on the desktop), and it can be used normally after power on; It is convenient for alternate use between different meeting rooms. According to the different signal strength and shielding area size of the conference room, the number of shielding equipment required for a single conference room may be between 1 and 3, depending on the specific situation.

2、 Mobile phone shielding scheme for large conference room (over 200 square meters) - accurate and distributed

2.1 scene features: the shielded area of a single conference room is large, or there is a signal amplifier in the room, so there can be no external interference.

2.2 basic shielding mode of mobile phone shielding in conference room (2G ~ 5g \ WiFi)

The main shielding equipment is selected as the engineering shielding host. The shielding host is installed in the sound control / lighting room or the ceiling. The directional flat antenna is placed in the ceiling of the conference room and connected through the feeder and coupling power divider. The shielding signal is transmitted from the shielding host to the flat antenna to realize the signal shielding of the conference room.

Main features: the antenna is hidden in the indoor ceiling, which does not affect the indoor decoration effect. Multiple antennas are evenly distributed to shield signals, with accurate shielding range and small electromagnetic radiation.

2.3 additional shielding coating

Shielding coating is added to the conference room to improve the shielding effect of the conference room and reduce signal overflow and external interference.

In general, the primary consideration in the design of the mobile phone shielding scheme in the conference room is the signal strength of the base station. When the signal strength cannot be determined, it can be used as a reference from the area angle to provide a certain support for the project promotion.
