Cell phone devices
use easy to access user friendly protocols for accessing voice and data
with easy information exchange. It's part of modern day communications.
However, the same easy communications access from your smart phone can
quickly and easily be modified (sometimes even remotely) that could turn
your smartphone into a bug transmitting all of your communications to
an eavesdropper. The CounterTeK GSM-box is designed to determine and display
the active state of mobile communication (GSM 900/1800, CDMA850, WCDMA2100
(3 g, UMTS) and Wi-Fi/Bluetooth). It automatically creates an acoustic
noise shield that will protect your conversations against illegal eavesdropping
when you need it! Small and compact, you can cary it with you and use
it with your cell phone whereever you go! Just place the GSM-box on top
of your cell phone and you are protected!
The CounterTeK
GSM-BOX has been designed to detect and indicate the illegal activation
of a mobile phone. In addition to this main functions, the CounterTeK
GSM-BOX also creates interference to the surrounding area of the telephone’s
microphone by generating ‘white noise’ when radio-waves are
detected; this noise suppresses the microphone in the telephone rendering
it useless.
Features:
• Warns with the 3 LEDs and a sound alarm when the telephone
starts exchanging data with the network
• Automatic generation of audio interference
• Accurate and sensitive detection of GSM 900/1800, CDMA850,
WCDMA2100 (3G, UMTS)and Wi-Fi/Bluetooth •
• by intelligent algorithm of the micro-controller
• Separate visual and sound an indication of different communication
protocols
• New convenient ‘credit card-style’ design suitable
for pocket use, belt carrying cases, bags, desktop stands, etc.
• A new sensitive scheme of detection with pre-selectors provides
better detection distance
• Does Not block the mobile network in the area
• No adverse effect on health (no electromagnetic waves)
• Frequency range of generated interference: 300-5000 Hz (white
noise)
• Sound pressure level in the area of the speaker: 90 dB
• Power Sources: 3V, CR2430 - Long battery resource of up
to 5 days (low current consumption)
• Dimension: 100x50x5 mm (4x2x0.2 inch)

Please Note: Most digital communication
devices might have a periodical exchange with the network with small packets
of data. This is not a danger, but rather a result of the mobile device’s
movement or registering with a network. Only activities with a longer
duration may be considered dangerous and should attract your attention.
