Is it necessary to conduct a field test before installing a full-band signal jammer?
Before installing a full-band gsm blocker, you need to know the size of the area to be shielded. For example, conference rooms are generally divided into three types: small conference rooms, medium-sized conference rooms, and large conference rooms. Before installation, the test methods for these three types of conference room full-band signal jammers are also different, and the environments of these three types of conference rooms are also completely different.
The small area is relatively small, the surrounding environment is relatively simple, and the requirements are not very high. During the test, you only need to place the full-band signal jammer on the desktop against the wall, and then test whether the mobile phone is interfered at the farthest distance from the device.
Medium-sized conference rooms are generally located in high-rise office buildings. The higher the floor, the stronger the signal from the base station to the conference room. In addition, there are basically signal amplifiers in the office building. It is necessary to test the signal strength of various frequency bands, and then Adjust each frequency band of the conference room shielding equipment, or increase the power of some frequency bands to meet the interference requirements of medium-sized conference rooms. A high-power module can be used to cover a certain frequency band with strong signal separately, and then use low-power The shielding device can interfere with the relatively weak mobile phone signal.
Large conference rooms are relatively large and can accommodate a large number of people, such as the Great Hall of the People. Used in this environment, shielding mobile phone signals is not an ordinary low power. A high-power full-band signal jammer is required to meet the purpose of covering the mobile phone signal of the entire conference room, and it is also necessary to adjust the signal strength of the transmitting signal source according to the signal strength of all mobile phone signal frequency bands within the tested venue range. The purpose of reducing the mobile phone signal in the venue, so that the full-band signal jammer can play the greatest role.
