The range of frequency interference sources is usually not a strict concept, but is determined by the situation in the area. A high-performance telephone signal in this range will reduce the distance the jammer can block the signal. On the other hand, if the cell phone signal in this area is low, the cell phone jammer will have a larger area to reach its maximum range. In order to select the necessary power source in the mobile jammer, you must know the power phone signal in the area.
If the ringtone of the phone disturbs the speaker’s thoughts at an important meeting, it will make him feel uneasy and distract the attendees. It is impolite to call on the cell phone in the meeting room. Therefore, in many meetings before the prompt, the phone will be turned off or enter silent mode. During this period, many companies do not allow mobile phones to participate in meetings. Visible on mobile phones, the ban on the use of mobile phones will be more clear. If you are in a meeting, how often do you hear the phone ring during the meeting? I think you will be as angry as I am, dissatisfied with this behavior, and even scold the owner of the phone. The unfortunate ending is not what we want to see. In order to avoid such unpleasant results, it is necessary to use cell phone jammers in the conference room. There are many advantages to using it in a meeting room. As can be seen from the above, uncivilized phenomena are prohibited. This not only prohibits mobile phone ringtones, but also prohibits the use of mobile phones during this period.
