Take A Closer Look At What Makes Your Cell Phone Jammer Work

Although cell phone jammers are quite simple to operate and do not have many visible components, they do have a number of highly technical components on the inside that make it possible for them to get their signal jamming job done right.

In fact, every cell phone jammer contains electronic components such as…

* Voltage-controlled oscillator
* Tuning circuit
* Noise generator
* RF amplification

The voltage-controlled oscillator on a cell phone jammer is designed to generate the radio signal that is needed to interfere with the signal produced by a cell phone. The tuning circuit, on the other hand, allows the user to control the frequency the jammer uses to broadcast its signal. In order to control the frequency, a certain voltage is sent to the oscillator.

The typical cell phone jammer also contains a noise generator, which produces a random electronic output within a specific frequency range. This way, it can jam the cell-phone network signal that is part of its tuning circuit.

Finally, the RF amplification component is used to boost the power of the radio frequency output. This boost is used to produce a frequency that is high enough to jam the signal.jammer circuit board image

Of course, even the best cell phone jammer needs to have a power supply. In the case of smaller cell phone jammers, the power supply is usually a battery. Stronger devices, however, may need to be plugged in or can be directly wired into the electrical system of a vehicle.

Be sure to check local regulations prior to operation of these devices as there are restrictions from country to country regarding their purchase, operation, and use.

Sophisticated cell phone jammers

Are You Looking For A Sophisticated Cell Phone Signal Jammer?
An Adjustable Cell Phone Jammer May Be Just What You Need!

If you are looking for a top-of-the-line cell phone signal jammer, you might be interested in an adjustable cell phone jammer.

Adjustable cell phone jammers are considered to be the most sophisticated type of jammer on the market today. This is because they are fixed units that contain adjustable settings, making it possible to keep cell phone chatter and disturbances away from large areas restricted from areas considered to be Mobile Free Zones.

There are a number of places where this more sophisticated type of phone jammer may be used. Some of these include…

* Hospitals
* Libraries
* Cinemas
* Theatres
* Prisons
* Schools
* Places of Worship
* Manufacturing Facilities

These institutions commonly maintain cellular-prohibited areas that may benefit from the ability to adjust the settings on a blocker without having to move it from place to place. These jammers are able to do this because they offer quad band technology and external antennas, making it possible for them to reach a larger area.

If you are uncertain about the type of cell phone jammer you need and reside or work in a country where they are permissible, contact the friendly folks at The Signal Jammer. Their representatives will be happy to help you find the jammer that fits your application and help provide you with the peace and quiet you desire.

Small cell phone jammers

From Big To Small…
A Cell Phone Jammer Can Get The Job Done!

When cell phone jammers first hit the market, consumers didn’t have many options to choose from. In fact, they were quite large and could be difficult to carry around.

Today, however, you will find many more cell phone jammer options available — and can even find some that are small enough to fit within the palm of your hand.

One of the great aspects of having a small cell phone jammer is the fact that you can carry one with you wherever you go! Why would you want to do this?

* Have you ever been caught in line at a fast food restaurant behind someone that won’t turn off his cell phone and place his order?

* Would you like to make sure that you don’t fall victim to a covert audio bug which may be hidden at your meeting place?
* Have you ever been caught in your morning bus commute, being forced to listen to every detail of last night’s escapades from one of the other commuters?

If so, you can appreciate the thought of having a small phone jammer that you can activate whenever you like!

When you use your personal cell phone jammer, you will enjoy…

* Instant peace and quiet
* Faster processing in lines when you are behind a cell phone user

Although the range of cellular phone jammers is not as broad as larger models currently on the market, they are large enough to help you bring peace and quiet to your personal space.

Cell phone jammers and emergency services

Are You Concerned About Using A Cell Phone Jammer?
Cell Phone Jammers Still Allow Access To Emergency Personnel!

Are you considering using a cell phone scrambler in your building or your place of business? If so, you are probably curious about how cell phone jammers actually work — and what effect they have on cell phones.

When you use a cell phone jammer, a lower power radio signal is broadcast. This signal is capable of cutting off communication between the cell phone and its cellular base stations. When this happens, all the cell phones in the area will show “No Service” — and incoming calls are blocked. To the caller, it simply seems as if the cell phone is turned off.

Although jamming cell phones causes them to have no service, certain pre-defined zones are not blocked. By default, these zones include…

* Fire
* Police

Therefore, when you use a cell phone scrambler, you don’t have to worry about putting yourself or anyone else in danger. Rather, police, fire, and EMS radio users can still communicate, but your customers won’t be disturbed by non-emergency cell phone chatter.

Once the cell phone jamming device is turned off, the phones will automatically reestablish communication with the cellular base stations — and those affected by the scrambler will once again be able to receive cellular services. The cell phone jammer does not damage phones in any way.
