In many countries, the use of Cell Phone Jammer is illegal due to the disruption it can cause in the communication service. If a cell phone jammer is placed near a hospital or public transportation area, then it can lead to failure in the communication process.
However, certain situations demand the requirement of setting up cell phone jammers, such as near an examination center. But, is it possible to detect a cell phone jammer? Yes, there are many advanced tools and techniques that can help you detect a cell phone jammer.
Let us walk you through this guide and help you understand how the cell phone jammer works and what tools and strategies you can use to detect it.
What is a Cell Phone Jammer?
A Cell Phone Jammer is a device that is designed to block the communication process within the set diameter. The technology used in cell phone jammers blocks cell phone communication through radio frequency signal, which is emitted at the same frequency as a mobile device.
A cell phone jammer blocks specific frequency bands that are meant for communicating with the mobile tower. Moreover, it emits the same signal as these cell towers which block the communication.
Is it possible to detect a cell phone jammer?
With the introduction to the latest technology, you can detect the signal jammer. However, the proof requires multiple attempts and going through trial and test methods. You need to detect the working signal to proceed with the cell phone jammer detection process.
However, if you are trying to pinpoint the exact location of the cell phone jammer, then you need to use highly developed military technology, which is not available to the common public.
How many types of jamming are possible?
There are two modes of jamming: Spot jamming and barrage jamming. Based on the policy implemented by spot jamming, here, concentrated power is directed toward one particular frequency. In the case of barrage jamming, the power gets spread over a range of areas, including several frequencies.
How do you avoid signal jamming?
To avoid signal jamming, the most common technique is frequency hopping (FH).
How to detect a cell phone jammer?
A Cell Phone Jammer is not easy to detect due to the nature of the radio frequency transmitted by the cell phone jammer. This makes it hard to pinpoint its actual location. However, by employing certain techniques, you can detect the presence of a cell phone jammer.
Here are the most common techniques that you can implement:
Signal strength monitoring
By identifying the signal strength of a mobile device, you can detect whether there is the presence of a cell phone jammer. The basic policy that jammers implement is that there is a signal fluctuation or complete loss of signal in the presence of a jammer. So, by monitoring the Receiving Signal Strength Indicator (RSSI) of a mobile device, you can easily detect it.
Specific issues can also occur due to the presence of a cell jammer – it can either result in call drops or repetitive failed connections. So, if you monitor the performance of a cellular network or if any anomaly is around it, then you can identify the presence of a cell phone jammer. Moreover, you can use different tools to monitor the network performance.
The process of analyzing the frequency spectrum of a signal is known as Spectrum analysis. Through this process, you get to identify the presence of interfering frequency. Now, to carry out the detection process, you have to use a Spectrum Analyser, which is an operator that can monitor the frequency used by a cell phone. If there is any unusual activity or signal spike in the frequency of the cell phone towers, then it indicates the presence of a jammer.
With the help of a Directional Antenna, you can look at the actual position of the cell phone jammer. The process is quite simple: you have to allow the operator to focus on the gain of the antenna in a specific direction. This antenna scans the environment, observes the changes in signal strength, and determines the location of the cell phone jammer.
Software Defined Radio (SDR)
Software Defined Radio (SDR) is the latest technology where you put into use software so that the device can perform radio frequency signal processing tasks and monitor through a wide range of frequency changes. You need to have the appropriate SDR receiver and software to proceed with the steps and identify the location of the cell phone jammer.
Radio Frequency can help you detect the presence of a cell phone jammer as it can identify the signals emitted through radio frequency. You can adjust the sensitivity and set the alert mode for the RF detector device, and whenever a particle signal is detected, you will get the information.
Collaborate with network operators
Local network operators can easily identify the presence of cell phone jammers. Thus, you can collaborate with them as they have access to advanced tools and data monitoring devices that can locate the actual source of the communication interference.
What is the range of a cell phone jammer?
A cell phone jammer is available in different forms and sizes, and if we consider the portable jammer, then it can block communication signals for a range of around 30 ft. However, in the case of bigger devices, the range can extend up to 1 mile.
