1. The effective shielding range of the test room signal jammer will be different in different use sites. This is closely related to the signal field strength on site. The shielding range of mobile phones of different standards may not be the same at the same site;

2. The factors that affect the shielding range include but are not limited to: distance from the base station, orientation, obstacles, the wall material of the site building, the installation height of the shield, the installation specifications, etc.;

3. Each antenna has a frequency band identification, which must correspond to the frequency band identification on the host one-to-one. Before turning on the jammer, ensure that each antenna is connected reliably. It is never allowed to turn on the device without connecting the antenna;

4. The surface temperature of the shield is about 40~50℃ after working for a long time, which is normal. If the surface temperature is too high, please turn off the power and try to contact your local dealer or agent;

5. The normal installation height is 1.8 meters ~ 2.5 meters, try to choose a place where there are no obstacles between the target shielding area. The wall-mounted installation requires the antenna to face up vertically. When placed on a desktop, the antenna can be folded 90 degrees and then up vertically. There should be no AC power lines or other audio and video lines within 0.2 meters of the antenna;

6. During use, in order to avoid possible interference with some electronic equipment, try to keep it at least 1 to 2 meters away from the following common equipment: audio, wireless microphone, radio, computer, TV, Wi-Fi router, etc.

The above are the precautions when using the test room signal jammer introduced by Jammer-mart. I hope it can help everyone.

All that you did not know about jammers for mobile

Many devices based on gps jammer are effectively used to protect personal information or business information. Possession of confidential data can greatly harm both the interests of a single person, and the whole enterprise. Almost everyone can need such a device, so we will try to figure out the main points of their device and application.

Many devices based on GPS signal jammer are effectively used to protect personal information or business information. Possession of confidential data can greatly harm both the interests of a single person, and the whole enterprise. Almost everyone can need such a device, so we will try to figure out the main points of their device and application.

What is the principle of work?

Jammers of cellular GSM signals, CDMA phones, Wi-Fi, 3G, Bluetooth signals, GPS jammers or anti-GPS trackers – they all work according to the general principle: signal emission in the same range as the suppressed signal. Around the device is created the so-called “white noise” and the signals are “lost” in it.

How do they look?

Signal jammer devices are:
stationary – from the name it is clear that this is a device of a noticeable size, weighing several kilograms, with the need to connect to the mains (some models have a battery). Installed in meeting rooms, cinemas, theaters, classrooms. Has the ability to block mobile signals at more than 10 radio frequencies and in a radius of up to 300 meters;
portable – these are inconspicuous compact devices weighing 300-700 grams that easily fit in your pocket. They work autonomously for a short time from one hour to three and with a radius of action of 5-10 meters;
Hybrid – these are the smallest in size devices that work from the cigarette lighter;
covers – look like ordinary covers for a mobile phone, but with the properties of a muffler.

The device is chosen, focusing on the method of use and the objectives pursued.

How to understand that a jammer works?

The best way to detect a gsm jammer is with a radio signal detector. This device also helps to detect spyware bugs. And in everyday life – if there is no communication signal at once on several mobile phones, then a silencer is definitely used.

Can I get around the jammer?

Standart and Premium class blockers are so powerful that they guarantee jammer of all signals in all ranges and in the declared radius, and you can only get around them using a walkie-talkie.

It is possible to bypass a GSM network jammer in several ways:
 using a walkie-talkie and earpiece
 portable Wi-Fi router + earpiece + micro camera
 repeater or additional antenna, with previously disabled mobile communications on the phone

Guaranteed 100% of the result does not give any of the proposed options.

In some countries, the Internet is disconnected throughout the country during state exams! In Russia, an educational institution to install a cell phone jammer is required to obtain permission from Roskomnadzor, if this requirement is not met, the device will be confiscated and a fine will be imposed.

What do we pay special attention to when choosing a jammer for a GSM signal?

The appearance of the device, its mobility and range are important. But if the battery runs out at the wrong time, this is unacceptable, so we carefully select the battery (duration and ease of replacement).

We hope that now, having basic information about jammers, choosing this device will not be difficult.

Jammers make you feel comfortable

Distracted driving is a trend that shows no signs of slowing down. Even though Manitoba imposes some of the most severe penalties in the country, a fine of $ 200 combined with five penalties, it still does not seem sufficient to prevent drivers from answering a call or text. The affected father, Hart Levine, designed a cell phone jammer called Drive ID. Global reports by Zahra Premji.

A car manufacturer has developed a compartment that blocks mobile phone signals.

Nissan says the Signal Shield prototype, built into the armrest of its Juke crossover, will eliminate distractions from incoming calls, messages and social media notifications.

The box works on the principle of the Faraday cage – invented in the 1830s – which uses a material such as a wire mesh to protect its contents from electromagnetic fields.

All mobile, Bluetooth and Wi-Fi signals are prevented from reaching the interior of the compartment once the cover is closed.

Penalties and fines for illegal telephone use by drivers doubled to six points and £ 200 on March 1 following a series of high profile cases and research suggesting the practice is widespread.

Nissan Motor GB general manager Alex Smith said, “Mobile phone use is a growing concern in the auto industry, particularly with the high number of push communications like texts, social media notifications. and application alerts. to reach their devices.

“The Nissan Signal Shield concept presents a possible solution to give drivers the choice to remove all distractions from smartphones while driving: it is about providing more control at the wheel, not less.

“Some pilots are immune to smartphone activity, but for those who struggle to ignore beeps and pings, this concept offers a simple solution in this very connected world in which we live.”

A RAC survey of more than 1,700 UK motorists found that the proportion of people admitting to using a mobile phone while driving increased from 8% in 2014 to 31% last year.

In October, truck driver Tomasz Kroker was jailed for 10 years after killing a woman and three children while plowing his stationary car while distracted by his phone on the A34 near Newbury, Berkshire.

Twenty-two people were killed and 99 seriously injured in accidents on UK roads in 2015, where a motorist using a mobile was a contributing factor, according to figures from the Department of Transport.

RAC spokesperson for road safety Pete Williams said, “Our research shows that driver use of the mobile phone has reached epidemic proportions.

“As mobile phone technology has evolved a lot, many people have become dependent on it, but using a mobile phone while driving is both a physical and mental distraction and has been illegal since 2003.

Using gps jammer can effectively solve this problem, place jammers in your car, your car without any signal, cell phone no signal status. So you cannot use mobile phones to focus on driving.

Frequently asked questions about cell phone jammers

1. When jammer phone while working, Why do some phone signals indicate that there is still a signal indication?
It’s just a false impression. In fact, this time the phone could not communicate. When you press the dial key, the signal indicator on the signal which is nothing remains.

2. Does the phone’s signal jammer interfere with the work of other electronic devices?
No. Since the telephone signal interferers emitted by the electromagnetic signal fall completely within the international requirements of the operating frequency band of the mobile phone, Block only the role of mobile communication. And this signal is still in a relatively static state, Will not act any electronic product.

3. Are cell phone jammer dangerous for the human body and the phone?
Please users comfortable. The signal strength of the electromagnetic signal emitted by the handset’s signal jammers is very low, Display test data force This signal strength is far away and does not cause harm to humans. At the same time, the phone signal jammers only block the front signal of the phone, so that the phone cannot contact the base station, so there is no damage on the phone itself.

4. Cell phone signal jammers The distance between inside and outside Are there any differences?
Of course. Telephone signal effective distance jammers usually refers to the indoor distance. Whether indoor or outdoor, effective in shielding the distance The range of interference will depend on the environment, such as the distance from the base station, the location of the installation and so on.

IG (Prison): Fixed a jammer

IG (Prison): Suman Gupta discovered misconduct at Ghaghidih Central Prison in Jamshedpur during an assault inspection. Gupta spent over two hours visiting the Central Prison for the first time and assessed the situation at that time, including the visitors, and communicated directly with the prisoners there. The IG prison expressed concern that even if it has been recently repaired, the cheap signal jammer installed in the central prison will not work. Additionally, the search by district police officers was unsuccessful.

Gupta expressed satisfaction with the fact that more than 30 CCTV cameras are working properly. She said she has given specific instructions to ensure that the CCTV camera is not damaged by anyone. Because they function as a third eye in prison. Sources said IG also contacted the inmates to understand their problems. It is worth noting that there are more than 1,450 prisoners, including prisoners in the Ghaghidih Central Prison. In June 2009, the Home Office conducted a survey of the prison and then recommended additional cell phone jammer to the prison. Sources continue to express concern about the situation in the prisons and the government plans to increase surveillance and deploy more security forces.

Inmates cannot use mobile devices because their signals are completely jammed and supervisors are free to use wireless networks (radio, smart phones, etc.). This is not everyone’s solution? I may be wrong, but I want to do it. Despite this, the problem still exists. There is no doubt that in addition to simply receiving calls and text messages, there are many smartphones that can connect to wireless networks. This can be a problem for signal blockers.

When we call someone or text messages, we use the standard GSM wireless frequency. In Europe and Asia, the GSM 900/1800 standard is widely used. It is used in GSM 850/1900 in the United States, Canada, and Latin America. These standards cover the 824 to 1990 MHz frequency band. The Wi-Fi frequency is completely different. When we use a Wi-Fi connection, our operating frequency is 2.4GHz to 2400-2483MHz. Therefore, the entire band that the compiler blocks will be 824-2483 MHz, which is a very broad spectrum. In addition to the wide frequency range that the necessary portable occluders have a configurable output power, it is also possible to work within a clear range to avoid interference that does not interfere with communication. To be honest, not all interferers can accomplish this task. But can provide the right solution for this particular task.
