cell phone dampener
Since the frequency band used by mobile phones is dedicated, the transmission frequency of the mobile phone signal jammer in the conference room is completely within the working frequency band of the mobile phone specified by the country, so it has no effect on other electronic equipment such as TVs and radios. At the same time, the cell phone signal blocker only interferes with the BCH transmitted by the base station received by the mobile phone, so that the mobile phone cannot establish contact with the base station, so it does not have any impact on the mobile phone. Furthermore, although the signal field strength it emits is stronger than that of BCH, it is far weaker than the electromagnetic radiation field generated during a mobile phone call. Therefore, it will not cause harm to the human body and can be used for a long time with confidence.
