WiFi Selectable , GPS Signal Jammer
Product Instructions:
This kind of mobile phone signal shielding device/partition, (also
known as a portable phone
jammers/suppressor/cutter/isolator/conference information
confidential machine) is our factory adopts advanced foreign
technology, mainly for domestic and foreign some special need
security and confidentiality of small places, such as private boss,
confidential office, negotiation rooms, the flow of vehicles,
mobile at the scene of the political and business leaders guards,
etc., according to the actual circumstance of domestic and foreign
mobile communication carefully developed high-tech products,It can
in a 1 to 10 metres radius (usually about 5-100 square metre)
blocking GSM/CDMA/DCS/PHS / 3 g/GPS/bluetooth/wi-fi wireless
networks such as signal, the mobile phone can't play and answer,
and does not interfere with other electronic equipment work within
the environment.When the phone is away from the screen, the range
can be returned to normal use.I'll give you a safety and a peace of
mind.

FAQ:
Why is there still a signal on the phone's signal indicator when it
works?
A: It's just an illusion.In fact, the mobile phone has been unable
to communicate.When you press the pull button, you will find that
there is no signal on the signal indicator.The cell phone signal
shield will not interfere with the normal work of other electronic
devices. The antenna should be installed on the corresponding signs
of each channel on the host, and then connected to the host power
supply.
The effective coverage of the shield is a circular area centered
around the shield, so be careful to choose the location of the
shield so as to avoid blocking the dead Angle?
A: No.This is because the electromagnetic signal emitted by the
cell phone's signal shield is completely within the country's
mobile operating band, which only blocks mobile communication.And
this signal is always in a relatively static state, and will not
affect any electronic equipment.
Are cell phone signal Jammer harmful to people and mobile phones?
A: Please rest assured that the electromagnetic signal intensity
emitted by the cell phone signal Jammer is very weak. The test data
indicates that this signal strength is far from harmful to the
human body.At the same time, the mobile phone signal shield is just
blocking the forward signal of the phone, so that the cell phone
cannot be connected with the base station, so there will be no
damage to the phone itself.
Is there any difference between the effective shielding distance of
the mobile phone signal shield in indoor and outdoor use?
A: There are.The effective shielding distance (30-40 meters) of the
cell phone signal shield is generally referred to as indoor
distance.In open areas, the effective distance of shielding can be
several hundred meters.It should be noted, whether they are within
the room, or in outdoor use, effective shielding effect of
shielding distance has relationship with environmental conditions,
such as from the base station near and far, placed, etc.Therefore,
when using cell phone signal shield, this factor should be fully
taken into account to avoid blocking the dead Angle and thus affect
the shielding effect.
Is the cellular signal shield the same for GSM mobile phones and
CDMA mobile phones?
A: that's a good question.Because CDMA mobile phone's
anti-interference performance is far superior to that of GSM mobile
phone, the effective shielding distance for CDMA mobile phone is
smaller than that of GSM mobile phone, but the difference is not
very large, about 2-4 meters.But it also reminds users to pay
attention to some particularly important sites, and should increase
the number of mobile phone signal blockers when necessary to ensure
the shielding effect of CDMA mobile phones.
After working for a period of time, the mobile phone signal mask is
hot. Will working long hours damage the machine?
A: thank you for your care. This is a normal phenomenon.In the
design, we use the thermal conductivity of aluminum alloy to assist
the heat dissipation.This can guarantee long time stable work.As a
result, the machine will not damage the machine.
