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. You’re probably wondering what is a cell phone detector?

What Is A Cell Phone Detector And What Does It Do?
A cell phone detector is a device used to sense the presence of an activated cell phone. A cell phone detector is 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. Similar to that of what a radio would put out. All the detector does 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.
Cell phone detectors come in a wide variety of options. Some devices are mounted in an area and are capable of alerting a central network that a device has been detected. Another option is a compact detector that can 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 A Cell Phone Detector Detect?
Any signal that is sent over the cell phone network itself will set off the doctor. That means any time you access a 4G, 3G, or a similar network. 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 cell phone detectors will go into enough detail for you to determine what frequency the cell phone is being broadcast on.
When Are Cell Phone Detectors Used?
There are a number of different uses for cell phone detectors. One of the most common reasons is to detect phone signals in areas where it is illegal to use a phone.
Some higher tier medical facilities for example or on airplanes. Military and law enforcement agencies also have uses for such devices.
One such law enforcement application is to detect illegal use of a cell phone inside a holding facility or jail. Illegal use of cell phones in these areas is a major problem.
You may also want to use these to detect phones in areas such as theatres or test halls where you don’t want people using phones.
Cell phone detectors are primarily used to prevent people from using cell phones where they are prohibited.
An Important Note About Cell Phone Detectors:
One thing you need to know about cell phone detectors is that they do not read any information from signals that are going back and forth.
They are just a detector. 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 which operate similarly to a cell phone detector 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.
