How different components of a mobile jammer work together?

A mobile jammer is a piece of electronic device used for disrupting mobile signals in a given area. It produces powerful signals at the frequency of mobile signals and broadcasts those signals to create a mobile free area within a few seconds of starting.

What is a mobile jammer and how it works?

A portable jamming device could be a pocket-size device with a 10-meter range or it could be a large piece with the 100-meter range of working. A jammer comes with multiple antennas – one each for GSM, 3G, and DCS. 

Important components of a mobile jammer:

Antenna: It transmits radio signals at a set frequency.
Voltage-controlled oscillator: It produces the radio signals for transmitting.
Tuning circuit: It keeps the frequency of the signals under control.
Noise generator: It produces random sound waves at a specific frequency to disrupt the mobile
        signals in a given range.
RF amplifier: It boosts the frequency of the radio waves to the point where they disrupt the                  mobile signals.
Power Supply: It supplies power to the main device.

The signals from the jammer are sent at such a force and within the same frequency that the mobiles become unusable within the range of a jammer. Cell phones are full-duplex devices. It means they use two types of signals – one for receiving and another for making calls. A basic jamming device would disrupt only one of these signals but it would disrupt two-way communication. 

Factors that affect the performance of a jammer

Presence of concrete structures and other obstructions could affect the performance of a jammer to a certain extent. Similarly, tower proximity, humidity, and temperature can also affect the functionality of a jammer. One more thing that can affect the device is its built quality and technology. When fully-functional, it can jam mobile connectivity completely.

What is a supportive security system and why is it important for home security?

Having a home security system can help ensure the safety of your family members and belongings in a great way but there has to be a supportive infrastructure for the security system. For instance, take doors. Every door should be made of tough material like steel but it learned that homeowners put more focus on the security of the main door instead of others.


They make the first line of defense of your home and for this reason, they have to be the strongest part of your home. It isn’t necessary that you use steel as wooden doors could be stronger than their steel counterparts. Your first priority should be the strength of the material and the design should be the secondary option. 


Windows often more open than doors and windows give access to the interior parts of a home. While there are many ways to bolster window designs, putting more focus on beautification could be compromising on the strength of window openings.


Electronic locks are more popular but manual locks haven’t disappeared completely. You shouldn’t compromise on the quality of manual locks while installing an electronic locking system. The manual locks are used when you are inside. Also, manual locks would improve the strength of your electronic locking system.

Multiple doors

A good idea to prevent opening your door for strangers is to use multiple doors. The main door should be protected with an access door that would give you ample time to think whether it is safe to open the door. Also, you can see the visitor from access door and even talk to him before opening the door. 

The entry-exit points of your home should be supportive of the CCTV and other security devices installed in the home. A strong door could resist forceful entry providing the CCTV ample time to record video and send an alarm signal.

To keep away from any unlawful or unauthorized entry of metal gadgets, bombs, knives, guns within the baggage bags of the character sporting them in public locations like theatres, purchasing shops, parks, airports, resorts, railway stations. Manually take a look at for everybody is pretty tough because of these metallic detectors comes in light. Some of the security devices come within the steel detectors variety are handheld metallic Detector, Door frame metallic Detector, and Explosive Detector. This web article will help you to get to recognize the short of the metal detectors operating. Let’s talk about handheld metallic Detector first. An HHMD is used in lots of safety assessments & additionally in electronic initiatives. The hand-held metal detector will come in light in the 1960s and changed into utilized in commercial packages. Basically, an ‘HHMD’ detector is a digital device that incorporates an oscillator which generates an AC contemporary that passes through a coil producing an alternating magnetic area. While even a small piece of steel is close by to the coil. The modern may be brought on in the metallic object & this generates a magnetic subject of its very own. If an extra coil is used to measure the magnetic discipline, the magnetic subject may be modified and sensed due to the steel object. Speak about ‘Door frame metal Detector’ as the call shows it's far a metallic detector outfitted in a door. This one is likewise referred to as ‘Walkthrough’ detectors. These are used for safety screening at getting entry to points in prisons, courthouses, and at airports to come across hid steel weapons on someone’s body. By using the everyday increments in an era, the DFMD’s also get up to date in various zones (like- One zone & Multi-zone Door frame metal Detectors). Where in the ‘Multi-zone’ it will cover more factors for looking as evaluate to ‘One zone’. At last ‘Explosive Detector’ comes, the one hand device allows distinguishing flammable drinks from non-flammable beverages. Specially use for airports & other traffic areas. It indicates effects in real-time detection. (Transportable gadgets comprise no radiation sources). There are many other metal detectors which are to be used for other purposes but can’t mention in the article due to lack of time. So, these are the big players in the security industry presently.
