Problem solving
1 Why do some mobile phone signal indications still have signal
indications when Bochuang spatiotemporal signal shield works?
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 the signal 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 Bochuang spatiotemporal signal shield 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 between indoor and
outdoor signal shields?
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 Bochuang spatiotemporal signal shield 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 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.
