GSM welding signal. The whole truth about how the jams are working in Russia

With advent mobile phones Communication between people has become much easier. Mobile phones allow you to save a huge amount of time, to quickly solve important issues and simply maintain a pleasant communication with a close person, which is at a distance. However, thanks to various spyware devices, a personal mobile phone can turn out of a faithful assistant to a source of permanent leakage of personal information, which can lead to serious problems.

Nowadays, in order to become the owner of a device that listens to mobile phones, it is not necessary to be a special agent or an intelligence. Anyone who wants both on the Internet and in specialized stores can buy bugs and install them anywhere.

Fortunately, protect your personal information and phone From the illegal invasion is quite simple. To do this, you need to have a muffler cellular communication And the silence of GSM and GLONASS signals. Fortunately, in order to protect themselves to buy such devices optionally. Experienced radio amateurs completely under the power of collecting devices overwhelming cellular signals with their own hands. About how the silence of telephone signals work, that they can and how to make them on their own, we will talk in this article.

GPS and GSM communication jams work on a fairly simple principle. When the telephone signals fall a zone of the passage of the frequency, then there are interference that block the ability to receive and send calls from mobile devices.

Silence GSM and GLONASS Signals, in turn, work on a different principle. They scan frequencies in the search for a specific signal, and as soon as it appears, the device begins to interfere and block the signal.

Cellular Silence Difference

The operation of GPS and GSM muffins primarily vary by radius of action. The simplest signs of signals work within a radius of 10 meters and effectively manifest themselves. More complex devices are designed for a radius of 50 meters. This is quite enough to protect themselves from the "bugs" in large rooms. There are also devicesallowing you to join the signals within a radius of several kilometers, but such equipment is used exclusively by special services.

Installation and use of the muffler

The installation scheme of the exhaust signal is very simple. You must screw the antenna in the instrument connector and turn it on. After switching on for 10 seconds, the device will muffle all detected signals. Signal blocker is able to work from the network and in offline mode. It is also easily charged from the car cigarette lighter.

Sometimes there is a situation when the suppressor of the phone, GSM and GPS signals does not work well, does not find the desired frequencies or something like that. So, occurs in the case when mobile operators use other frequencies. In order for the device to catch all frequencies, you must perform the following steps:

• Remove the switch;
• Unscrew the antenna;
• Remove the device cover;
• Extract the microchip of the device;

· To adjust the purity using a screwdriver on the chip twisted the trimming resistor.

The legality of the use of suppressors of communication

According to the law "On Communication"which operates in our country, any devices of the overwhelming signals of mobile phones or other devices in obligatory Certificate and registration. And if the certificate can be obtained from sellers when buying, you need to register the device yourself. In case of non-compliance with the rules of the current law, the violators are facing a fine, and the application of the device is considered illegal. Although it is worth noting that for the illegal use of such devices to justice is attracted very rarely, and when it comes to the preservation of personal information, such conditions are justified by the risk.

Who can listen to you

Install bugs and listen to your phones Even schoolchildren can. Purchase listening devices on the Internet is very easy. But mainly by the use of "wiretapping" usually resort to law enforcement officers, wanting to produce compromising on criminals, influential businessmen who want to eliminate competitors, jealous husbands suspecting wives in treason and so on. So not to become a victim It is necessary to protect yourself from the leakage of information using exemplary signals.

How to make telephone jammed with your own hands

On the Internet you can find enough various schemesWith which the effective suppressor GPS and GSM signals can be constructed independently. Most often, the telephone extender operates at a frequency of 800 MHz. Since most mobile phones are configured to this frequency. Despite the simplicity of the principle of operation of the device, for his self-assembly Requires certain skills.

In order to make the home suppressor GSM and GPS itself, it is necessary to take a generator of synchronous signals with a frequency of 45 MHz, which reacts the port of the heteroodine. As a result, interference appears. Next, an antenna for frequency 800 is configured on the generator MHz. After that, the RF-output is connected to the amplifier, due to which the power of the device increases to 16 dBm. Next, already stressed signal Served to the device antenna. The finishing stage of the self-assembly of the device is considered the hand-made body to which the battery is installed, and the switch is created. In general, the finished suppressor of signals will be mainly from:

• Voltage controlled (GUN);
• Amplifying cascade;
• Source of interference;
• Schema;
• Antennas.

The scheme of one of these devices is presented below:

Conclusion

From the foregoing it becomes clear that the muffler cellular communication in the modern high-tech world is a very useful device that will help save personal information and protect you from the emergence of a huge number of unpleasant situations. Buy such a device today is very simple, And if you are also an experienced radio amateur, it can easily collect such a device yourself.

GSM / GPS alarms are compatible with SIM cards of any cellular operators and work everywhere where there is a zone of the GSM signal coating.

Using the GSM alarm, you can start and turn off the car engine from any place, regardless of the distance. Receive information from signaling about closed doors, trunk, hood, ignition condition and all kinds of electronic sensors.

Some modules implements the ability to listen to the cabin using a mobile phone.

GSM auto alarms equipped with a GPS module constantly have information on satellite canals Communication about the location of the car and the speed of movement.
Information about GPS coordinates will be sent to a mobile phone. You can immediately open the map with the location of your car on your mobile phone or on the Internet site.

Well, that's how about each manufacturer describes the operation of your module. Some moments I allocated let that later it became clear why.

All is well and great in them. They cost from 4.500r to 30.000r with autonomous meals and a bunch of any additional relays, whatever the attacker could turn it off. But not one more productively says that all the essence of the work this deviceno matter how much it should be based on work cellular operator.

And now to the case ....
Now cellular operators work according to the following standards:
2G - digital cellular communication
900/1800 MHz (used in Europe, Asia)

Characteristics................................................. GSM-900 ........ GSM-1800
MS transmission frequencies and reception BTS, MHz 890 - 915 1710 - 1785
Frequencies of receiving MS and BTS transmission, MHz 935 - 960 1805 - 1880
Duplex transfer frequency and transmission frequencies, MHz 45 95
The number of frequency communication channels with a width of 1 communication channel in 200 kHz 124 374
Communication channel bandwidth, kHz 200 200
There is still 2100 MHz. This is already 3G connection. 3G - Broadband Digital Cellular Communication Committed Multipurpose computer networks, including the Internet

"The muffler"

Muffler cell phones or cellular suppressor GSM, 3G, CDMA - This is a mobile communication channel blocking device at specified frequencies in order to ensure personal safety. Cellular muffins are with different radius of action and suppress various communication frequencies. The suppressor of communication can be pocket or stationary, jammed both cellular channels of various frequencies and channels of wireless video cameras and microphone radio. The radius of the silencers depends on various factors. This is a distance from the base station of the cellular operator, the wall thickness of the room in which the suppressor of cell phones is used, as well as the output power of the GSM muffler itself.

Mobile phone suppressors duffle only specified frequency ranges, Therefore, other devices operate in normal mode when the muffler is turned on. For example, while the cellular communication GSM and 3G is blocked, the Internet via WiFi channel and DECT phone will work. The silencer of cell phones does not have a negative impact on human health. As a rule, the output power of the suppressants is small and for a person harmless.

The cell phone blocker works silently and absolutely does not affect the nearby household appliances, office equipment, computers.

We received the greatest distribution pocket cell phone suppressors. These are small mouse fouls that fit in pockets and blocking cellular communication in a small radius, an average of up to 10 meters. Pocket mobile muffler has a built-in battery and can continuously work up to 5 hours. The use of such blocks, as a rule, is associated with the protection of a personal car, with the need to conduct confidential departures, as well as the muffler of the cellular is used to suppress GSM bugs - the most common devices for the hidden wiretapping. The pocket suppressor of mobile phones can also be applied in antiterrorist purposes, for example, when neutralizing the mechanisms of fuses activated by calling to the built-in cell phone.

Stationary suppressors of cell phones, As a rule, have a greater supply radius than pocket models. On average it is about 50 meters. Stationary muffles are used mainly in offices and meeting rooms for meetings. Also these mobile phone blocks can be installed in schools, universities, libraries and in sumps for cars. GSM The muffler with a large radius of action is often mounted in correctional institutions.


Intelligent Mobile Phone Silencer It has a function recognition function, that is, in standby mode, the phone works and the level of communication does not fall. But as soon as the phone is trying to make a call or comes incoming callThe exhaust signal is triggered and blocks the communication channel. The muffler of mobile phones with an intelligent function is convenient what only when it is necessary.

GPS Silence Signalcreated to suppress signals satellite navigation GPS. GPS suppressor jams various trackers, beams and satellite tracking systems. There are GSM, 3G cell phone blocks and satellite GPS satellite navigation combined in one device.

Suppressor WiFi, Bluetooth, wireless cameras, radio microphones and bugs- This is a muffler, which suppresses the frequency of transmission of wireless video cameras and bugs, as well as WiFi and Bluetooth channels. The blocking of hidden wireless video cameras reliably protects from the unwashed video. The muffler of the camcorder and bugs is a pocket blocker that can be used where hidden video and wiretapping is possible.

So, the muffler of cell phones, cellular suppressors, video cameras and microphone blocks, GPS silencers are generators of interference in the specified frequencies that serve to ensure personal security, negotiations and meetings, the preservation of state secrets and protection of the country.

Mobile phones, as you know, have recently become a means of hidden listener and unwashed removal of data, speech information in the place of stay of the owner of the tube. Enough to install special in the phone software, or send an SMS command, and you can listen to the phone and receive information through the microphone and the phone video camera, even when there is no connection. The muffler of cellular mobile phones allows you to neutralize such hidden removal of information. The mobile suppressor blocks the signal and the listener is neutralized. GSM bug, a small box is less than a matchbox, works on the same frequencies as phones. Muffler mobile signal GSM blocks the work of such bugs and plus it quickly plant a bug battery, because Bug will continuously try to establish a connection. The stationary block of phones will not only protect the selected room from the wiretapping, but also will promptly disable a bug, dischargeing their battery.

Now their characteristics (remember above GSM communication standards):

Pressed standards: GSM, DECT, CDMA (Skylink), 3G

Effective suppression distance:
For GSM, DECT, 3G standards up to 40 m
For SKYLINK communication networks (CDMA) up to 20 m
Operating frequency ranges: 450 ... 470 MHz, 869 ... 960 MHz, 1700 ... 1800 MHz, 1805 ... 1925 MHz, 2050 ... 2150 MHZ

Power: For pocket versions, it is 8 finger batteries or one battery.

Yes, I almost forgot, the cost of such toys from 5.000r and to 25.000r stationary middle class.

Let's sum up!

Through such a krenovin in your car and take it into a sump, where one more such is stationary and disassemble it all for the presence of such modules. And you convulsely send SMS to her number and in response silence.
So then you think about it, but is it worth spending money on the purchase and installation of such prambians?!
I'm still a supporter of the next list:
1.Pishkali C. feedback (not combined with CZ)
2.Dop.immobilizer
3.Maehanic locking of the steering wheel or box (better steering, the clutch squeezed and drooped the car, and then pick it up in the next yard until the owner woke up)

P.S. Make the findings themselves, decide to you!
P.S.S. Wanted everyone who likes it))))

Thanks for attention!

that's what I dug off on the forum from 2008

The scope of this device has a lot, and the result of the action is always one - the reduction of the radio signal. You can go for the purchase of this gadget. Here is represented a large number of Mufflers with different range of action. What is suitable for one or another sphere, we will analyze below. In the meantime, we recommend sign up for future purchase.

How to Aliexpress find cellular jams

A cellular muffler, first of all, a microcircuit that is suitable for a radio signal suppression. Such goods are sold in a specially designated section, and it's not so easy to find it, because it is a spyware and it is allowed to use not everywhere. The desired section "". On the main online page. There is a list of popular sections (left). Follow the active line "Watch all" (all categories).

On the new page descend to the header "". Themed subsections will be enshrined below it. Click on ".

The tab with a multitude of electron microcircuits will open to reduce the time to search for suitable, go to the adjacent category "". There will be more than 170,000 products and alone chips are similar to others. If you do not understand the type of board, then you will find it manually to find it. Apply the filter menu that is in the left part of the section.

Go down to the line "Type". Tick \u200b\u200bthere "Voltage Regulator" there. In the next application, select Computer. Thus, you will load a list of goods corresponding to the value. Among them, choose a suitable muffler.

For those who know the specific area of \u200b\u200bthe use of the muffler, you can use the search string. Enter the name there and click on the search button. For example, "Data Module" or "GSM Quad Module". So you will get unloading from suitable goods.

Radio Silence and Law, which says law

Namely a cellular signal, is a spyware. And it is necessary to apply it for any of its goals. Either this is done by law or against him. You can order from China, however, it will need to be registered. Again, it is necessary to register such a product only if there are certificates and if they have high power. If you plan to comply with all the points of the law, then require the seller's relevant documentation. As a rule, this path is chosen by commercial and government organizations that can prove the need of such a silencer.

On the other hand, private individuals can enjoy. It will be able to get permission to use it only if you are able to prove the need to install the device. For example, in a hospital, prison or school is quite acceptable to use the muffler, but to combat constantly ringing neighbors or passing chatters under the windows of your home, this option will not pass. We will have to invent the reason for effective use. This is evidenced by the "law on communication", which states that all radio transmission devices need to register. If there is no registration, they cannot be changed. Almost all silencers of radio signals are used illegally. Know that the detection of such devices threatens at least administrative responsibility.

To whom and why need a muffler cellular communication, Wi-Fi, voice recorders, GSM signal

Devices can be used for many purposes. Among them are legal consumption of overwhelming jammer and illegal For which a considerable fine can be seal or, even worse, a criminal term.

Everyone remembers the wonderful school times when the tickets passed. Now the time of EGE, GIA and other tests that require the confiscation of mobile phones came. Some students manage to carry cell phones and try writing off. At such a case in examined classes, they can not get the phone with their help incoming callAnd also make an outgoing.

Many and other places where it is used, it can be theater, cinema, museum, bank. A lot of government agencies and commercial firms in which meetings and meetings are held requiring silence. Particular attention is paid to the suppression of cellular communication in prisons and colonies, where communication on mobile phones is prohibited.

Many users are ordered for private use. For example, to join the bonds of annoying neighbors, for a block of communication during operation. Most cars are equipped with GLONASS systems that control the movement of transport. To "limit" control, some resort to with their help information with data on the movement will be lost. Instead of signals about movement on the monitor screen, there will be a message on the similarity of "Error". The same tracker also enjoy many car hijackers, but this is a completely different story.

Overview of the models of Glushokok

Divided by type of execution and type of the suppressed signal. The first were developed silencers of bugs they are configured on the range of listening device. They work from the battery and enough for several hours. Next, the device requires recharging and may again "go to battle". There are many such devices, but one of is GSM jummer. It is shuffling outgoing and incoming call signals, SMS messages and Internet access. Depending on the model selected model, a set of muffler functions may differ.

In its kind, the muffler looks like a block with several boards and wires, it is crowned with several antennas. This is if you take in pure form. In fact, he may look like a tutu cigarette or a compact cell phone. To conspict the device, manufacturers come up with different images. If you order a "naked" device, you can adjust it yourself and disguise.

Another is it blocks outgoing data in such a way that they cannot be transmitted to the tracking monitor. They stand are somewhat more expensive than mobile suppressors. The cellular wave failure is often included in their functions. It turns out a device 2 in 1, sometimes 3 in 1. When buying such devices, always remember the law and the legitimacy of their use.

The most purchased muffles with Aliexpress

Silencers of radio waves are often bought for interest. To do this choose the most simple modelsaimed at blocking incoming calls that can cost about 300-400 rubles. But sometimes the buyer clearly knows the set of functions and chooses the device somewhat more expensive. We will try to figure out how to find the most purchased muffles. The first thing you should do is enter the section "". Next, use the menu on the top panel of the section in question. Choose there "Orders". So you will learn a list of models of communication blocks that users ordered the greatest number time.

Here is a list of signal silencers:

• . Works in GSM / GPRS bands, including 850, 900, 1800, 1900 MHz;
• Supports standard GSM07.07, 07.05 AT commands and advanced AI commands;
• GPRS / GSM is compatible with Arduino;
