How does a signal jammer interfere with mobile phone signals?
Mobile phone has become one of the
necessary tools in our travel, on the contrary, the demand for mobile phone
signal jamming equipment has gradually become more and more. When we use a
mobile phone to make a call, we use the uplink frequency to contact the base
station, and then the signal of the base station is sent to the mobile phone
through the operator to realize the call function. When the mobile phone is in
standby, the mobile phone still keeps in touch with the base station through
the uplink signal. Once there is a call demand, the mobile phone call and
information transmission can be realized through the operator at any time. The
signal jammer is a device that interferes by sending the same signal frequency.
If the mobile phone shows no signal when using the signal jammer, the jamming
is successful. Nowadays, with the increasing number of mobile phone users, it
is inevitable that some places will be prohibited from making calls, sending
messages and surfing the Internet, and the signal jammer has become a very
useful tool in these places.
Today's signal jammers can not only
interfere with mobile phone signals, but also interfere with GPS positioning
signals. Their functions are becoming more powerful. There are different types
of jamming devices sold in the market at present. Some devices can interfere
with single terminal signal frequency, while others can interfere with multiple
signal frequency bands at the same time. The former has a single interference
frequency band and more specialized interference effect, while the latter has
more types of interference signals and more complete interference functions.
Jamming equipment of different frequency bands can be selected according to
requirements.
