Perhaps have been reading about cell phone danger, cell phone safety or cell phone radiation to your head
and are concerned for yourself and your loved ones. On this web site you will get straight answers.
You can reduce by approximately 90% (sometimes more) the cell phone radiation (the radio frequency energy) to your head
with our device. We will tell you how and show/demonstrate its usage here in these web pages. We will show you our laboratory test data.
We have data from our own microwave (radiation) laboratory
for testing with the NASA / Military method of testing radiation reduction (attenuation). We don't make vague, non-specific references like "tested by a major laboratory". On our Engineering page, we will discuss what a microwave is, and what a microwave laboratory is. There are links at the top of each page to take you to any other page.
In this web site we will describe the physics of cell phone radiation
to your head that you have no doubt been wondering about. Specifically, we will discuss the radiation that is coming off your Cell Phone antenna and travelling to your head. We will provide credible, expert explanations of various approaches to reduce radiation, including
the dreadfully bad idea of using a Blue Tooth
wireless headset/microphone.
You don't have to buy anything to receive this lesson in Electronic Engineering and Physics! Just keep reading and also visit our Engineering page.
Best of the best
We do not manufacture this product. We have surveyed other original equipment manufacturer's products and after 2.5 years of testing in our own microwave radiation laboratory, we have selected the best of the best and are marketing it under our own name.
We were shocked and dismayed
to read the ads on the Internet for cell phone radiation reduction devices that used scare tactics like "
your cell phone is killing you
",
and make audacious claims for the device they are selling, like
"
this product will save your life
".
We have seen so many sites for products that seem to be run by people that are hiding their identities, no resumes, no curriculum vitae, no street addresses, no phone numbers. Do these people exist? Why are they hiding?
You must be frustrated and confused
with so many web sites and experts claiming: cell phone danger, cell phone health issues, cell phone safety issues, and simultaneously reading that the cell phone makers and cell phone carriers indicate that there is little or no such problem. Who should you believe?
Perhaps you have come to the conclusion that it's a good idea to reduce the cell phone radiation exposure to you and your loved ones. We want to help.
We are doing our job only, and doing it well.
You may notice that in our words we never assert that cell phones are in fact dangerous, that cell phone radiation is bad for you, that adults and children are in harms way when using cell phones, etc. It is the job of the government to determine if there is a problem. If so, then the government must set standards and regulate that industry.
For the persons who have decided for themselves, that there may be cell phone health or cell phone safety issues to be concerned with, and want to reduce cell phone radiation to their head, our job, as we see it:
- provide a device that reduces cell phone radiation to a persons head who is using a wired ear-piece / head-set,
- provide testing / characterization of that device that is credible, and state-of-the-art

The Cellular concept is that there are sites, often referred-to as towers, that connect through radio frequencies to the cell phone that you carry in your hand. Each of these towers has a certain coverage area and that area is what we call the cell.
The basic idea is that if you have enough small cells in a given area, you can provide good service to a large numbers of users, simultaneously.

When you speak, sound waves radiate from your mouth to the surrounding area.

This radio wave radiation is often referred-to by its most general name in physics, namely, electromagnetic radiation.
Radio waves have a specific length associated with them. The higher the frequency of the radio wave, the shorter the wavelength. When waves get to be quite short, they are referred-to as microwaves, but it is still the very same basic phenomenon: radio waves (electromagnetic radiation).';

Mhz means megahertz (millions of cycles per second).
Ghz means gigahertz (billions of cycles per second).
In the early days of cell phones, they were analog phones. Said another way, they were not digital phones. They operated, and some still do, in the 824 Mhz to 896 Mhz range. These will sometimes be referred-to as the 850 Mhz region, or even the 800 Mhz region.
As time went on, a digital version of cell phones was authorized by the FCC, in the same basic 850 Mhz region.
Then a new concept emerged. It is called Personal Communication Service (PCS). It operates in the 1850 MHz to 1990MHz range and is sometimes referred-to as the 1900 Mhz region or the 1.9 Ghz region. The vast majority of the cell phones that people use today should most properly be called PCS phones. The PCS system is digital and has many convenience features associated with it, including short text messaging and two-way radio service. NOTE: people think that Nextel invented the push-to-talk two way radio feature that they offer. In fact it was always in the PCS specification, but until today, few carriers implemented it (offered it as a service).
It seems that the U.S. and Europe have to be different. Europe has a type of system for cell phones called GSM (General Services Mobile). There are a few carriers in the U.S. who offer GSM service. Yes, you have to have a cell phone that is designed for GSM in order to use GSM.
Some cell phones have dual band of tri band capability and can operate throughout different carrier service networks.
Most carriers feel that one day the entire cell phone world will be GSM-based.';

Some of this RF (microwave) energy couples into (gets onto) the ear piece wire that is going from your Cell Phone to the ear piece that is positioned in your ear. The wire, usually of a primarily copper construction, is quite happy to carry the RF. It can carry it reasonably efficiently up to your head.

There is a Cell Phone ear piece that is referred-to as an "air phone". It has a wired connection to an audio transducer module. From this module, a hollow tube brings the sound to the ear. The tube is plastic. The idea here is that the tube will not conduct the RF to the persons head.
We are often asked whether this is a viable approach to reduce Cell Phone RF to the head. As long as the length of the tube is such that it extends down to a location that is approximately 1/2 of the distance from the waist to the chin then this approach is effective. Some of these products that we have seen are sized so that the air tube only extends from the ear, down to the chin (of the person wearing it). If you are going to use such a device you might consider trying to get a model that extends the tube down to a point that is 1/2 way between the chin and the waist (of the person who is wearing it).
It may be a bit more bulky and heavier then our Noble1 device. Its cost might be more, as well. We also feel that the use of a tube to conduct the audio frequencies will give a bit of a "in a barrel" sound and therefore the receive audio will most likely be a higher quality with our Noble1 device and a conventional wired ear piece.
You could also use the Noble1 device on the wired portion of such a device to increase the effectiveness of the whole system (air phone + Noble1) for the reduction of RF to a persons head.';

Transmit audio quality using the speakerphone feature of a Cell phone is not all that great, but if you speak up, and the noise in your environment is not too high, it can be an acceptable approach.

$xtip = 'BlueTooth Wireless Earpiece - A Really Bad Idea
You may have seen people wearing an ear piece that has no wires connected to it. In addition, this device has a microphone as part of it. This is most probably a BlueTooth wireless earphone/microphone.
BlueTooth is the name of a specific type of wireless (Radio Frequency) technology. BlueTooth uses specific frequencies, and communicates using specific protocols. It is intended for wireless connectivity over very short distances - less than 10 meters. Mostly it was intended to allow various computer peripherals (keyboard, mouse, etc.) to wirelessly connect to the PC.
The BlueTooth approach for Cell Phone usage, uses a BlueTooth transmitter in the Cell Phone and a BlueTooth receiver in the ear piece so that the user (the person wearing the BlueTooth device) can hear the other party on the Cell Phone call. In addition, and here comes the problem, there is BlueTooth transmitter in the ear piece that communicates with a BlueTooth receiver in the Cell Phone so that when the user speaks, his/her voice will be connected to the Cell Phone.
If a BlueTooth device is used for the convenience of not having wires coming from an ear piece to a Cell Phone that is, say, on the users belt, well then it could be more convenient … in a way. Of course you now have another device to buy batteries for (The BlueTooth earpiece).
If the BlueTooth device is being used to keep the Cell phone radiation away from the users head, then this is an insane idea. There is a BlueTooth transmitter in the BlueTooth device! The radiation from that BlueTooth device is in the users ear. Its in his/her head!
Also, the BlueTooth frequencies, are closer to the optimum frequency for heating biological tissues. BlueTooth frequencies are in the same band of frequencies as microwave ovens.
We have heard arguments that the power of the BlueTooth transmitter that is in the ear piece, is less (power) than that of a Cell Phone. While this is probably true, since BlueTooth transmitter is so close to the persons head, one would really be defeating themselves in using a BlueTooth earpiece for reducing RF to the head.
All in all, it a user wants to reduce RF to his/her head, a BlueTooth wireless earphone/microphone is a dreadfully bad idea.';

The BlueTooth approach for Cell Phone usage, uses a BlueTooth transmitter in the Cell Phone and a BlueTooth receiver in the ear piece so that the user (the person wearing the BlueTooth device) can hear the other party on the Cell Phone call. In addition, and here comes the problem, there is BlueTooth transmitter in the ear piece that communicates with a BlueTooth receiver in the Cell Phone so that when the user speaks, his/her voice will be connected to the Cell Phone.
If a BlueTooth device is used for the convenience of not having wires coming from an ear piece to a Cell Phone that is, say, on the users belt, well then it could be more convenient … in a way. Of course you now have another device to buy batteries for (The BlueTooth earpiece).
If the BlueTooth device is being used to keep the Cell phone radiation away from the users head, then this is an insane idea. There is a BlueTooth transmitter in the BlueTooth device! The radiation from that BlueTooth device is in the users ear. Its in his/her head!
Also, the BlueTooth frequencies, are closer to the optimum frequency for heating biological tissues. BlueTooth frequencies are in the same band of frequencies as microwave ovens.
We have heard arguments that the power of the BlueTooth transmitter that is in the ear piece, is less (power) than that of a Cell Phone. While this is probably true, since BlueTooth transmitter is so close to the persons head, one would really be defeating themselves in using a BlueTooth earpiece for reducing RF to the head.
All in all, it a user wants to reduce RF to his/her head, a BlueTooth wireless earphone/microphone is a dreadfully bad idea.

As time went on, a digital version of cell phones was authorized by the FCC, in the same basic 850 Mhz region.
Then a new concept emerged. It is called Personal Communication Service (PCS). It operates in the 1850 MHz to 1990MHz range and is sometimes referred-to as the 1900 Mhz region or the 1.9 Ghz region. The vast majority of the cell phones that people use today should most properly be called PCS phones. The PCS system is digital and has many convenience features associated with it, including short text messaging and two-way radio service. NOTE: people think that Nextel invented the push-to-talk two way radio feature that they offer. In fact it was always in the PCS specification, but until today, few carriers implemented it (offered it as a service).
It seems that the U.S. and Europe have to be different. Europe has a type of system for cell phones called GSM (General Services Mobile). There are a few carriers in the U.S. who offer GSM service. Yes, you have to have a cell phone that is designed for GSM in order to use GSM.

There is a Cell Phone ear piece that is referred-to as an "air phone". It has a wired connection to an audio transducer module. From this module, a hollow tube brings the sound to the ear. The tube is plastic. The idea here is that the tube will not conduct the RF to the persons head.
We are often asked whether this is a viable approach to reduce Cell Phone RF to the head. As long as the length of the tube is such that it extends down to a location that is approximately 1/2 of the distance from the waist to the chin then this approach is effective. Some of these products that we have seen are sized so that the air tube only extends from the ear, down to the chin (of the person wearing it). If you are going to use such a device you might consider trying to get a model that extends the tube down to a point that is 1/2 way between the chin and the waist (of the person who is wearing it).
It may be a bit more bulky and heavier then our Noble1 device. Its cost might be more, as well. We also feel that the use of a tube to conduct the audio frequencies will give a bit of a "in a barrel" sound and therefore the receive audio will most likely be a higher quality with our Noble1 device and a conventional wired ear piece.
You could also use the Noble1 device on the wired portion of such a device to increase the effectiveness of the whole system (air phone + Noble1) for the reduction of RF to a persons head.';

Transmit audio quality using the speakerphone feature of a Cell phone is not all that great, but if you speak up, and the noise in your environment is not too high, it can be an acceptable approach.
