Mobile phone signal jammers are often used in our study and life, including conference rooms in enterprises and institutions. As technology develops, conference room facilities become more complete, and signal jammer blockers are one of the most common devices. When using mobile phone signal jammers in conference rooms safely, you need to pay attention to the following two points.

1. Mobile phone signal jammers in conference rooms have a certain range of use

Although the mobile phone signal jammer device is called a jammer, it does not actually block the signal. Instead, another name is more suitable for it - signal jammer. Generally speaking, the connection between mobile phones will pass through the base station, that is, the path of mobile phone-base station-mobile phone. The signal jammer will interfere with the communication path between the mobile phone and the base station, resulting in abnormal transmission. However, the base station is shared by mobile phones within a certain range, so there are often situations where mobile phone signals cannot be used normally even when not in the conference room.

2. Mobile phone signal jammers in conference rooms are not omnipotent.

Mobile phone signal jammers currently on the market can limit mobile phone signals that are 500M meters away from the transmitting station and have a radius of >20 meters. The shielding radius is adjustable, it only blocks mobile phone signals and does not affect other electronic devices.

How to choose a conference room cell phone signal jammer device?

We provide you with high-quality conference room cell phone signal blocking solutions:

  1. According to the size of the conference room. For example, the types of jammers used in conference rooms of 100 square meters and 200 square meters are completely different.
  2. According to the usage time of mobile phone signal jammer in the conference room. According to our general understanding, if the signal jammer is used frequently and for 5 hours a week, then a commercial machine can be used, and the price is relatively low. If the signal jammer is used for more than 20 hours per week, industrial-type jammers are used, and the price is relatively high.
  3. Use the on-site signal strength according to the signal jammer. In the category of conference rooms, it is not easy to judge. We usually judge based on whether there is a signal amplifier in the office, whether there is an operator base station 300 meters away, and the usual signal strength of the mobile phone. If the mobile phone signal is strong, you need to use A slightly more powerful jammer.
  4. According to the signal frequency band required to be shielded. There are several different solutions for conference room signal shielding, such as blocking full-band mobile phone signals, including 234G and the latest 5G mobile phone signal frequency bands. There is also a method that does not block the call frequency band, with the purpose of allowing participants in the conference room to You can't play with your phone and can only receive important calls.

How to test cell phone signal jammer device in different size conference room ?

Conference Room Size Features Jammer Test Method
Small conference room Small area, simple environment When testing, just place the conference room jammer on the table against the wall, and then test whether the mobile phone is blocked at the farthest end from the conference room jammer.
Medium conference room Generally on high floors The higher the floor, the stronger the signal from the base station to the conference room, and there is basically an indoor signal amplification system in the building. It is necessary to test the signal strength of various frequency bands separately, and then adjust the conference room jammer to meet the mobile phone signal shielding requirements of medium-sized conference rooms.
Large conference room A place that accommodates hundreds or even thousands of people for meetings A high-power conference room jammer is required, and according to the signal strength of all mobile phone signal frequency bands within the tested venue, the signal strength of the transmitting signal source should be adjusted to reduce the mobile phone signal in the venue.
