Cloaktec blocks virtually all consumer wireless signals.
Shielding Theory
Electromagnetic shielding (cloaktec) is used to shield electromagnetic signals such as radio signals from leaving or entering a box or enclosure.
Attenuation
is simply a reduction of signal strength during transmission. You represent attenuation in decibels (dB), which is ten times the logarithm of the signal power at a particular input divided by the signal power at an output of a specified medium. It is expressed as the base 10 logarithm of the ratio of the powers of two signals:
20 dB attenuation means that 0.0100 of the input power survives
40 dB attenuation means that 0.0001 of the input power survives
Cloaktec(TM) has an adv. attenuation of 80 dB in the wireless signal range of 10 MHz to 20 GHz, or 0.00000001 of the input signal.
