In order to better protect the legitimate rights and interests of many students, the signal blocker is an artifact in the examination room. Like other major candidates, the use of signal jammers has also attracted widespread attention in this year's college entrance examination. So many misconceptions in application must be paid close attention to. Generally speaking, what are the common problems that must be kept in mind? ?Let’s get to know each other:
1. Detection panel signal ECG monitors will have different effective shielding ranges in different application sites. This is closely related to the magnetic field strength of the local signal. Different types of mobile phones may have the same shielding range on the same website, so the selection should be based on the actual situation.
2. Factors that affect the scope of shielding include but are not limited to distance, location, clear objects relative to the base station, wall materials of the building at the site, installation height of the protective cover, installation specifications, etc., and other factors as well. To get attention.
3. Each wireless antenna has a frequency band identifier, which must correspond to the frequency band identifier on the server. Before the shielding is turned on, be sure to ensure that each wireless antenna is connected reliably. Do not use it without Equipment is used in the case of wireless antennas.
4. After long-term operation of the shield, it is normal for the surface temperature to rise above 40 degrees.
5. The normal installation height of the signal jammer for cell phone is 1.8 meters to 2.5 meters, and it should be installed in a place where there are no obstacles between the target shielding area and the target shielding area. If the antenna needs to be pointed upright in a wall-mounted installation; when placing the dining table, the antenna can be extended 90 degrees and then pointed upright.
6. During the use process, in order to avoid possible impact on some electronic products, the following common equipment should be used to maintain a distance of 1~2 meters.
