What Are Mobile Phone Network Signal Jammers? An Overview

Mobile phones are being misused at a very threatening level nowadays. Right from being a threat to someone’s security to being a weapon for cheating in exams, this technology is being used for some of the worst reasons in the world.

Thankfully technology has not only created phones, but Mobile Phone Network Signal Jammers as well!

What are Jammers?

 Jammers are devices that disable any communication from mobile phone or GPS in its effective area. These jammers can be portable as well as stationary. The use of jammers has increased manifold in the last few years and they now find applicability in military, education departments, meetings, VIP security, as well as the corporate sectors.

How do Jammers work?

 Mobile phones or any other communication devices work through transmission of radio waves. The nearby mobile tower receives the transmission and sends a signal to the receivers’ mobile, which in turn makes communication possible.

 To prevent such communication, jammers transmit signals of the same frequency as the mobile phones and interfere with the mobile’s transmission to the cellular tower. This interference disables the mobile network thus barring it from communication of any sort.

What are the various uses of a Jammer?

 The mobile phone network signal jammers are used for various purposes; some of them are listed below:

 ●        Military area - Highly sensitive areas like military cantonments install mobile phone jammers to disable any transmission for the purpose of security. These jammers prevent the military hub from spying activities as well.

 ●        Examination Halls - Easy entry of high-tech cheating devices like ultra small Bluetooth devices, pen cameras and mobile phones enable cheating during examinations. Portable mobile phone jammers block the communication of such devices with gadgets outside the examination centre, thus playing a successful role in enabling fair conduct of examinations.

  ●        Prison Mobile phone Jammers - Mobile phones can easily be smuggled inside the prison and act as a threat to the system’s security as inmates use them to re-establish harmful contacts with their allies. The stationary jammers installed in the prisons act as an excellent tool to prevent such incidents and maintain the sanctity of the system.

  The usage of mobile phone signal jammers has increased a lot in the last few years. With the advancement of technology, usage of these jammers has become a necessity for all the reputed educational institutions as well as for high security areas. The mobile phone network signal jammers thus acts as a multi-purpose tool, whether it is needed in an examination hall or in the parliament house.

How Military Jammers can change warfare?

In this digital era, the term ‘Spectrum Warfare’ has replaced the term ‘Electronic Warfare (EW).’ Spectrum Warfare is a blend of electronic warfare technologies and electro-optical technology. It involves usage of devices like Powerful Signal Jammers for Military, interception, radars, electronic spoofing, infrared sensors, multi-spectral and hyper spectral sensors, visible-light sensors and laser technologies.

An enormous amount of strength and accuracy has been infused by the usage of the afore-mentioned technical advancements, thus creating a much better detection system in the armed forces and a higher capacity to combat impending attacks. Currently the radar system is frequently being used to detect real-time enemy actions and to identify their location to help missile launches at the targeted locations. The radar jamming technology offers a perfect solution to warfare threats through emission of radio signals at a specific frequency, which in turn degrades the quality of enemy’s radar detection system. Thus these strong Signal Jammers are effectively mislead the enemy and act as a deterrent towards implementation of rival strategy.

Influential countries in the world are employing mobile phone Signal Jammers to enhance their security measures. These countries have successfully implemented jamming technology to demoralize the rivals.

Usage Of Mobile Phone Jammers In Hospitals

The ideal atmosphere of a hospital is quite depressive and stressful. There is a lot of hustle and bustle going on in general wards and emergency wards whereas pin drop silence is expected to be maintained in the operation theaters. Not to forget, we are surrounded with nincompoops who find it difficult to understand how to behave at what place. Needless to explain, there is a need for a solution that puts an end to this kind of nuisance. Mobile Phone Signal Jammers are a definite solution to put an end to the connectivity device based issues in various areas inside the hospital.

 It would be wrong to say that the entire hospital vicinity must be equipped with jammers since the staff, the patients admitted in the hospital, the relatives of the patients need to contact the outside world. There is no way that barring cellular communication in the complete hospital campus would lead to a positive result. There is a fine line between a necessary communication and the communication that causes disturbance.

 To create a balance in a situation like this the most wise decision will be install low radius jammers in and around operation theatres. Leaving the rest of the hospital campus to be jammer free so that the hospital staff, the patients and their relatives can make make the necessary phone calls in the other wards of the hospital.

 So, now that we are aware of where the jammers are used in the hospital, let us gain a clear perspective on why are jammers used in the hospitals:

 To avoid disturbance:

 Under strict government permission and a valid license the hospitals use mobile signal jammers to cut down any kind of unwanted communication.

 To avoid frequency merge of the radio signal operated medical devices and the cellular signals:

 The hospitals bring into use many radio signal machines. The signal of these machines can be interrupted by the cellular signals, bluetooth signals or the wireless devices used by the visitors or the hospital staff. The signal jammers are capable of blocking a specific kind of frequency. Thus, the frequency that is capable of merging or disturbing the radio signal operated medical devices, are blocked with the help of jammers.

 To Conclude

  The use of jammers in hospitals is practiced under the permission and guidance of the government. There is a legal license issued by the government for the usage of jammers by the hospitals. There are certain areas in a hospital where the signals are jammed using 2G 3G mobile phone network jammers to avoid disturbance in that area.

Everything You Need To Know About Mobile Network Signal Jammers

In this blog, we aim to cover all the aspects of a jammer. So let us begin with understanding the basics: What are Jammers? A jammer is a device that is used to intentionally block connectivity signals like mobile networks, infrared rays, bluetooth connectivity, WIFI connectivity, radio signals, etc.

So, we know that jammers are electronic devices that are used to block signals in order to curb unwanted communications. Let us further take a look at the list of the places where the network jammers are used.

Application of the Mobile Signal Jammers:

Prisons: Jammers are installed in prisons to bar the signals of the prisoners using any kind of communication equipments to converse within themselves or the outside world. Hospitals: Hospitals have areas like the operation theatres, emergency wards, etc. that require utter attention and thus, to avoid distraction via devices, jammers are installed in hospitals.

Defence, Military & Police: The Defence, Military & Police personnel make use of jammers to curb any kind of unwanted communication in the area. The Defence forces make use of military jammers to block IEDs and radio signals.

Classrooms: In order to stop the students from technical cheating, the school board makes use of jammers to disrupt the signals. Meetings/Conferences: The boards make active use of jammers these days to carry out distraction free meetings and conferences. Convoy/Vehicles: To protect and secure the VIP movements ,transportation of critical assets and property, often jammers are installed to bar unwanted wireless signals.

It is a great experience to be able to communicate with anyone at any point of time. The problem arises when people don’t know where and when to stop talking. The main reason why places like churches, cinema halls, restaurant, live play theatres have begun installing jammers in the vicinity. Let us further read to understand how jammers work. 

How does a Mobile Signal Jammer work?

The jamming device attacks the frequency to which the cellular network is connected and disrupts the signals to block the communication.  Let us understand this better with a little bit of details.  

Jammers transmit a high-power signal of the same frequency as that of the cell phone, in a way that both the signals collide and cancel each other out. A majority of the jammers use this working module for blocking the signals. The low quality devices have the option of blocking devices of one frequency only. Whereas the high-quality devices are capable of blocking multiple frequencies at the same time.

Cell phones being the full-duplex devices, use two different frequencies; one for receiving the signals and the other for sending out signals, i.e. one for listening and the other for talking. There are some basic jammers that only block one of these frequencies. However, blocking one signal out of the two has the same effect as of blocking one. This happens because even when one signal is blocked, the cell phone assumes that there is no service available. Since the mobile needs two frequencies to function properly, the functioning of the mobile is disrupted.

There are some jammers that create a new frequency in order to create noise and disturb the cellular communication. By generating noise on a new frequency the cellular signal is interrupted.

 Components of a Jammer

  Antenna: Jammers come with an attached antenna which is used      for transmitting radio signals.    

Voltage-controlled oscillator: It produces the radio signal which overrides the phone     signal.

Tuning circuit: There is a tuning circuit installed in jammers that     help in controlling the frequency of the radio signals.  

Noise generator: Produces random noise in a particular frequency range     to jam the network.

RF amplifier: The RF jammer is an extremely important component that     does the task of boosting the frequency to a level high enough to jam the     network.

Power supply: As the name suggests, it supplies power to the jamming     device.

 So, this was all about jammers. We aimed at covering all the possible dimensions of a jammer. Beginning from what is a jammer, it’s applications, how a jammer works, and its components. I hope by now you are well versed with the basics of Jammers.
