How to keep off the annoying phone calls
with a polite way and have no bad effects on others? Here an rich experienced
jammer manufacture www.jammerall.com
will give you the best answer as you need.
To jam the signal of a cell phone, all you
need is a device that broadcasts on the correct frequencies with the one that
out of the nearby base station. Although different cellular systems process
signals differently, all cell-phone networks use radio signals that can be
interrupted. Different countries may adopt different frequencies. To
effectively keep off the phone calls, the high power 3G 4G
mobile phone jammer can broadcast on any frequency and are effective against
CDMA, GSM and DCS. Old-fashioned analog cell phones and today's digital devices
are equally susceptible to jamming. The actual range of the jammer depends on
its jamming range. Less complex devices block only one group of frequencies,
while sophisticated jammers can block several types of networks at once to head
off dual-mode or tri-mode phones that automatically switch among different
network types to find an open signal. Just like this high power 3G 4G
Mobile Phone Jammer and UHF VHF WiFi Jammer, which has the power to block the
mobile phone signal, UHF VHF and WiFi signal just in one kit, this is the magic
of the high technology world. The mechanical part of the high power jammer
contains the main body, 8 bands and car or AC adaptor, which allows use in case
of power fail.
Needless to say, mobile phone has become
the urban device when it comes to networking and staying connected anywhere
anytime. Mobile phones help you stay closer to your family, enable you to
contact for help instantly, catch up with your friends, schedule a meeting, and
even inform your family when you are stuck in traffic coming back home. On the
other hand, mobile phone calls also make our life annoying sometimes, at that
time, purchasing a high power mobile phone jammer will be a wise choice for
you. Need one? Go and clink one now.
