Bcsk-808m2 mobile phone signal shield
of Bochuang spacetime brand is a high-tech product carefully developed by our factory with foreign advanced technology, in view of the continuous development of communication system and according to the actual situation of foreign mobile communication. It can cut off GSM / CDMA / AMPS / DCS / PHS / 3G (WCDMA TD-SCDMA and CDMA2000), 4G mobile phone signals and 2.4G wireless signals
make the mobile phone unable to send and receive messages, but will not interfere with the work of other electronic devices, so as to ensure the safety of the required place. When the mobile phone leaves the partition range, it can resume normal use without any damage to the human body.
1. Effectively shield all communication signals such as CDMA (China Telecom), GSM (China Mobile, China Unicom), SCDMA (Netcom, PHS), DCS (1800MHz), PCS (1900MHz), PHS (Telecom PHS), 3G mobile phone signals and 4G mobile phone signals,
2. Ultra thin shell, the surface can be labeled or silk screen printed according to customers' needs (silk screen printing service is provided free of charge)
3. Transmission Power 12W
The host is guaranteed within 1 year and maintained for life.

1. When the signal interference shield
of Bochuang space-time brand works, why do some mobile phone signal indications still have signal indications?
A: This is just an illusion. In fact, at this time, the mobile phone has been unable to communicate. When you press the pull-out button at will, you will find that there is no signal indication on the signal indicator.
2 will Bochuang spatiotemporal brand signal interference shield interfere with the normal operation of other electronic equipment?
A: No. This is because the electromagnetic signal sent by the signal shield completely falls within the working frequency band of the mobile phone specified by the state, which will only block the mobile phone communication. And this signal is always in a relatively static state and will not affect any electronic equipment.
3 is the signal interference shield of Bochuang spatiotemporal brand harmful to human body and mobile phone?
A: please rest assured that the electromagnetic signal intensity emitted by the signal shield is very weak. The test data show that this signal intensity will not cause harm to the human body. At the same time, the signal shield only blocks the forward signal of the mobile phone, so that the mobile phone can not contact the base station, so it will not cause any damage to the mobile phone itself.
4 is there any difference in the action distance of Bochuang spatiotemporal brand signal interference shield when used indoors and outdoors?
A: Yes. The effective distance (10-40m) of signal shield generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach hundreds of meters. It should be noted that whether used indoors or outdoors, the effective working distance of the shield is related to the environmental conditions at that time, such as the distance from the base station, the location, etc. Therefore, when using the signal shield, this factor should be fully considered to avoid shielding dead angle, which will affect the shielding effect.
5. Does the signal interference
shield of Bochuang spatiotemporal brand have the same effect on GSM mobile phones and CDMA mobile phones?
A: that's a good question. Because the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the effective shielding distance of signal shield for CDMA mobile phones is less than that of GSM mobile phones, but the difference is not very large, about 2-4m. However, users are also reminded that in some particularly important places, if necessary, the number of signal shields in the field should be increased to ensure the shielding effect of CDMA mobile phones.
6. After the signal interference shield of Bochuang spatiotemporal
brand works for a period of time, the casing is hot. Will it damage the machine after working for a long time?
A: Thank you for your care. This is a normal phenomenon. In design, we use the thermal conductivity of aluminum alloy wire drawing casing to assist heat dissipation. So as to ensure long-term stable operation. Therefore, the hot casing will not damage the machine.
