This is just an illusion. In fact, the mobile phone at this time has been unable to communicate. When you press the unplug button at will, you will find that there is no signal indication on the signal indicator. Will not. This is because the electromagnetic signal emitted by Cell Phone Disruptor Blocker completely falls within the working frequency band specified by the state, and will only block the wireless electromagnetic signal in the shielded place. And this signal is always in a relatively static state and will not affect other electronic devices. Please rest assured that the strength of the electromagnetic signal emitted by the cell phone jammer is very weak and meets environmental protection standards. Tests have shown that this signal strength is far from harming the human body. At the same time, the cell phone jammer just blocks the forward signal of the cell phone, so that the cell phone cannot contact the base station, so it will not cause any damage to the cell phone itself at all.
There is a difference. Usually, the outdoor signal strength is greater than that of the indoor, so the outdoor shielding effect is poor. Strictly speaking, whether it is used indoors or outdoors, the effective distance of Cell Phone Disruptor Blocker has a certain relationship with the electromagnetic environment of the shielding place and the surrounding environment. For example, the distance between the wireless signal transmitting equipment outside the venue and the wireless communication device in the venue, and the location where they are placed. It depends on the distance between the wireless communication signal transmitting device and the receiving device. Since the transmission distance of 2.4GHz wireless communication equipment is limited by national standards, the transmission distance is much smaller than the transmission distance of base station communication signals. Under the condition of the same distance between transmitting and receiving equipment, the shielding range of 2.4GHz wireless communication equipment is slightly larger than that of mobile phones. The opposite happens when the signal is weak unless the base station is far from the shielded site. It is a normal phenomenon for the heat sink of the mobile phone signal jammer to heat up. In terms of design, we use the thermal conductivity of the aluminum alloy high-performance heat sink to dissipate the heat generated by the equipment during operation, so as to ensure that the machine can work stably for a long time. Therefore, the heat of the heat sink will not damage the machine.
