2. What is CleanSignal Technology?
CleanSignal is application of our multi-band filter and shielding technology to reduce Electromagnetic Interference/Radio Frequency Interference (EMI/RFI) in electronics and communications circuits and associated hardware.
Interference degrades communication signals and causes problems like dropped cell calls, poor Wi-Fi or GPS reception. Increasing power input (boosting the signal) to minimize interference leads to limited battery life.
Application of CleanSignal reduces noise due to Electromagnetic Interference/Radio Frequency Interference (EMI/RFI) and Passive Intermodulation (PIM) without the need for additional power to boost the input signal.
For example, in antenna applications CleanSignal improves the Signal-to-Noise Ratio (SNR) by 3 dB to 10 dB, effectively increasing the wireless communication range by a factor of 2 to 10, or reducing the power requirements by up to 50% to 90%.
In shielding applications CleanSignal has been tested to provide effective shielding(attenuation) in excess of 120 dB.
More energy efficient and reliable telecommunications infrastructure, fewer dropped calls, reliable GPS positioning and improved battery life, - is now possible with CleanSignal.

3. How Does CleanSignal Work?
CleanSignal reduces noise from Electromagnetic Interference/Radio Frequency Interference (EMI/RFI) and Passive Intermodulation (PIM) interference using multi-band filter (band pass filtering) technology.
CleanSignal boots performance by filtering background noise and provides improvements of 3 to 10 dB gain in Signal-to-Noise Ratio (SNR) in antenna applications. It’s much like using your hand to cup (shield) your ear to improve hearing in a crowded restaurant, or cupping your hands to your mouth when cheering your favorite team.
In shielding applications CleanSignal has been tested to provide effective shielding(attenuation) in excess of 120 dB.
CleanSignal is tunable and has been tested in the 3 MHz 1.2 THz frequency ranges.
Applications include antennas, circuit boards, cables, and enclosures. Our materials are available as absorbers or reflectors in multiple material formats, e.g. structures, panels, fabrics, flexible mats.
The technology is lightweight, strong, cost effective, scalable, and can be designed to meet specifications.

5. What is a decibel (dB)?
According to Wikipedia - http://en.wikipedia.org/wiki/Decibel:
The decibel (dB) is a logarithmic unit that indicates the ratio of a measured physical quantity (usually power or intensity) relative to a specified or implied reference level.
A decibel is one tenth of a bel, a seldom-used unit named in honor of Alexander Graham Bell.
The decibel is used for a wide variety of measurements in science and engineering, most prominently in acoustics, electronics, and control theory.
In electronics, the gains of amplifiers, attenuation of signals, and Signal-to-Noise Ratio (SNR) are often expressed in decibels.
A change in power ratio by a factor of 10 is a 10 dB change. A change in power ratio by a factor of two is approximately a 3 dB change.
A ratio in decibels is ten times the logarithm to base 10 of the ratio of two power quantities, P1 (signal) and P2 (noise):

6. What does 3 to 10 dB improvement mean?
A change in Signal-to-Noise Ratio (SNR) by a factor of two is approximately a 3 dB change.
For example, tests have shown that the use of CleanSignal in Wi-Fi applications has provided gains in SNR in excess of 3dB. This implies:
a. You require half the power normally used for the Wi-Fi application to get the same signal reception, i.e. a potential of 50% savings in power consumption by the Wi-Fi device.
b. You can receive the same quality of signal at 1.5 x times (50% improvement) in coverage range after applying CleanSignal technology, i.e. an increase of wireless communication range.
Here is a helpful table with approximate gains as related to gains in dB:
Gain (dB) Gain Descriptions 3 dB 2 x gain 6 dB 2 x 2 x gain = 4 x gain 9 dB 2 x 2 x 2 x gain = 8 x gain 10 dB 10 x gain
CleanSignal technology has been tested to provide 3 dB to 10 dB gain over conventional antenna technologies.
In shielding applications CleanSignal has been tested to provide effective shielding(attenuation) in excess of 120 dB.
Performance improvements can be in the form of improved signal, reduced power requirements or increased communication range depending on the application.

7. What is Passive Intermodulation (PIM)?
Passive Intermodulation (PIM) is electronic noise or interference.
Inter-modulation refers to a series of unwanted frequencies created whenever two or more frequencies pass through a nonlinear device or junction.
