How effective is the mobile phone jammer placed on the ground?
All customers who have purchased mobile phone jammers are very concerned about the actual shielding effect of the
shielding device when they receive the product and conduct a power-on test.
Different customers must have differences in the test environment, the method
of testing and the testing methods. There are also differences in the mobile
phones used, so there will be large differences in the test results returned.
Among them, the placement or installation position of the shielding equipment
is also a key factor affecting the shielding effect. Then the question arises,
if the mobile phone jammer is placed directly on the ground, how effective is
it?
Usually, when the manufacturer of mobile
phone jammers sells the shielding equipment, there will be a detailed
installation and use instruction in the package box of the goods. Let us take
the most common low-power mobile phone jammers used in indoor environments as
an example. There should be special installation instructions in the manual.
The first choice is wall-mounted installation. It is recommended that the user
keep the installation height of the shielding device between 1.8 meters and 2.5
meters, because this height is just at a position that is not easily accessible
to human hands, which can prevent future use. During the process, someone will
maliciously damage the shielding device or artificially cut off the power or
shut down. At the same time, this installation height also exceeds the height
of almost all furniture, tables, chairs or other furnishings in the room, so
that the shielding signal of the mobile phone signal jammer can be transmitted
unimpeded, and the shielding signal can be covered to every room in the room to
the greatest extent. corner.
If it is inconvenient to use the
wall-mounted installation method, but directly place the mobile phone signal
shielding device on the table, this can be regarded as a compromise method,
which is suitable for short-term and temporary work scenarios. Since the height
of the conventional desktop is about 0.8 meters, if the mobile phone jammer is
placed directly on the desktop, the shielding signal will be more or less
affected by some furniture or obstacles with a height of more than 1 meter
during the transmission to the surroundings. Influenced by objects, this will
actually reduce the final shielding effect.
Finally, analyze what will happen if the
mobile phone jammer is placed directly on the ground: unless the room is
completely empty, the tables, chairs or furniture in the room will become
obstacles in the process of shielding signal transmission. More or less will
attenuate the shielding signal, and this attenuation will be superimposed as
the number of obstacles increases. This will seriously affect the shielding
distance of the mobile phone jammer. It is the most undesirable way to use the
shielding device on the ground for testing and use.
