Cell phones are everywhere in the modern world, even kids have them. Along with the invention of cell phones, there have been many tools invented to work with them. One of those tools is the cell phone detector. Have you heard about cell phone detectors before?
What Are Cell Phone Detectors And What Do They Do?
Cell phone detectors are devices that are used to sense the presence of an activated cell phone.
These devices are simply used to look for active cell phones within a certain range.
For the most part, these devices do not jam the signal, they only detect the usage of cell phones.
Whenever a cell phone is using a cellular network, it connects to a specific radio frequency.
These radio frequencies are similar to that of what a radio would put out. All the detectors do is look for these signals.
Different cell phone companies use different frequencies. The frequencies also vary from one country to another.
Countries utilize a wide range of cell phone technology and some are at higher levels of technology than others, thus resulting in different frequencies that need to be looked for.
These detectors come in a wide variety of options. Some are mounted in an area and are capable of alerting a central network that a cell phone has been detected.
While others are compact and they are small enough to fit in your hand.
Alerts typically come in one of several ways. A common method is to have a LED light that illuminates when a signal is detected. Some have multiple LEDs to show strength.
Another method of alerting is a screen that provides you with an information read out. The last common method is an audio alert that you can hear when a signal is detected.
Sometimes multiple methods are combined to provide a variety of alerts.
What Can Be Detected?
So data and voice transmitted over any of the major networks will be detected. Depending on the level of technology built into the detector you can get different types of detection.
Some detectors will just tell you that there is a signal in use. While others will tell you how far away that signal is.
And some detectors will provide enough detail for you to determine what frequency the cell phone is being broadcast on.
When And Where Are These Detectors Used?
There are a number of different uses for these devices. One of the most common reasons to detect phone signals is to prevent people from using cell phones in areas where it is illegal to use them.
For example, in some higher tier medical facilities as well as airplanes, cell phone use is prohibited.
Military and law enforcement agencies also have uses for cell phone detectors.
One such law enforcement application is to detect illegal usage of a cell phone inside a holding facility or jail.
Illegal usage of cell phones in the areas mentioned above are a major problem in our society today.
You may also want to use cell phone detectors to detect cell phones in areas such as theatres or test halls where you don’t want people using cell phones.
Cell phone detectors are primarily used to prevent people from using cell phones where they are prohibited.
An Important You Should Know:
One thing you need to know about these detectors is that they do not read any information from signals that are going back and forth.
They just detect cell phones. Any attempts to obstruct cell phone signals could be illegal. Many countries have laws against cell phone jammers and similar technology.
There are other devices that operate similarly to cell phone detectors by detecting a wide range of signals.
These devices are more complicated to use and often require some level of specialized knowledge and/or training.
Signal detectors are a relatively new idea when it comes to a compact design specifically targeted towards looking for cell phones.
