... designed for all wireless communications and mostly cellular bands
(GSM850, GSM900, GSM1800, GSM1900, iDEN, NEXTEL, TDMA, AMPS, CDMA, NMT,
DCS, PHS, PCS, 3G, UMTS, etc.)... Cellular telephones and other requested
communication devices (Radio-Communications, Wi-Fi, GPS, Satellite Phones etc.)
located in the protected area cannot transmit or receive. Devices located
outside the area will have regular services and will not be affected by the PRO
Jammer. Unlike KAVIT's state of the art jammers, competitive products may suffer from serious problems of stability and
reliability.
KAVIT's battle-proven products are used by the most demanding forces &
agencies worldwide.
Typical
Applications: Security - RCIED / EOD / ECM / VIP / Anti-Eavesdropping &
Anti-Communication, Safety, Privacy, Acoustic Isolation. What is RCIED?
RCIED stands for "Remote
Controlled Improvised Electronic Device". In other words, RCIED is a RC (remote controlled)
Bomb. RCIEDs are widely used by terrorists
worldwide mainly in conflict zones, and have been causing a large number of casualties, especially to the
US forces in Iraq & Afghanistan.
A typical RCIED is composed of a bomb, attached to a cellular phone. After installing the RCIED
in sensitive locations like main roadsides, the
terrorist can then dial to activate it from anywhere and at any time, of course
he would wait for the right moment in order to maximize the human injury.
By accurate and effective operation, the Kavit PRO Jammers cut off the RC
triggering transmissions to the RCIED receiver, thus immediately preventing bomb
denotation, and save life, sometimes of many.
If you want the best for
your Army, equip it with Kavit
Professional Jammers.

Broadband Jammer e.g. "20-2500MHz", is it
a good solution ?
Not really. The larger the
total bandwidth covered by the jammer, the less the effective time/power which
each frequency point gets. In fact there are even more issues which won't
be detailed here.
Programmable DDS / DDS+PLL Jammers, is it an advantage ?
Not really. A
'friendly' communication
window for your
needs is equally friendly also for your enemy needs... Moreover, even for
commercial purposes, a small window provided by programmable jammers is very noisy what makes them unacceptable for many
applications, even with filtering.
Limitation of Electronic Jammers:
Unfortunately the 'smart bad guys'
could always overcome any jammer in various ways e.g. by exploiting the
unlimited frequencies spectrum and so on.
The conclusion is that, unless there are specific known frequencies threats in
certain arena, jammers are generally destined to cope only with the 'normal bad guys', who
use popular available devices like cellular telephones. Therefore, at this time, Kavit recommends
that the customer consider the minimal vital frequency ranges required for his
application.
KAVIT is able to
quickly provide you with the most professional and cost effective solutions for
ANY realistic requirements of jamming systems.
What about FCC or CE ?
Jammers (of any kind,
any vendor) can never pass any such or similar standard. If any vendor claims to
have FCC/CE for its jammer, we'll be happy to hear about the model and its
'certification' number.
Cellular Activity Detection & Responsive Jammers
In theory, it could be
better (e.g. in terms of longer battery operation time) if the
jammer could be responsive, and operate for certain [programmable] period whenever a cellular activity
is detected. However, for
security purposes it shall not be done:
Regardless of the vendor, once a jammer is switched on, it usually takes time until the cellular phone becomes disabled. This period
may be more than enough to activate the RCIED.
Similarly, in case of prison application, a prisoner may be able to send a SMS message [or even make a
shortest voice call] every time after the detection-activated jamming
period stops.
About coverage range...
Some companies specify
jamming distances
which are unrealistic, at least not for the desired environment, where the
cellular RSSI (received signal strength indication) for instance is not so low. The simple fact is that the jamming coverage radius depends not
only on the jammer itself, but also on a variety of additional factors e.g. the cellular
RSSI from the respective BS (base station) at
the target arena, the cell phone type and model, frequency band and modulation
type, terrain shape,
quality and directivity of interfering obstacles and more. If a cell phone is located
for instance near
its respective BS, the cellular RSSI will be high and as a result the jamming range will be
smaller.
Conclusion: instead of referring to meaningless
coverage specifications, refer to a Professional Manufacturer, which will tailor
for you an optimal jammer based on your detailed vital requirements.
Central Control System ?
Kavit Jammers e.g.
KJ2000 & KJ4000 series can be
equipped with an option to support Control &
Monitoring System,
allowing to easily control
all jammers from a central
command or place.
Please do not hesitate to contact us, we will be happy to advise on the best
solution for your applications.
