Telephone jammers are necessary for a good environment for important meetings

We’re tired of being interrupted, especially in important places, and I’m tired of the phone ringing. He was very angry when the leader was chairing an important meeting and was interrupted by the ringing of the cell phone. The frequency jammer is used in the conference room so that the conference has a good environment.

With the popularity of cell phones, cell phone ringtone makes people more tired, especially in some quiet public places. In many places, cellphone use is prohibited as it affects others, affects others to rest or work, and even affect the websites such as the use of the instrument and the moderating effect of cellphone. While there are clear instructions on how to ban cell phone use, there are a lot of people in these places using gas stations for example, as we use cell phone at gas stations is dangerous and probably caused the explosion.

We should know that the important national meeting will last for many days. The content of the meeting must be kept strictly confidential and must not be interrupted by the outside world. Therefore, the mobile phone is prohibited. Not only is this a national meeting, but it was also adopted at a series of corporate meetings where cell phones were banned and cell phone blockers were gradually installed. What do you think is reasonable about Office installation of the cell phone jammer?

Not only are cell phones banned in gas stations, but many public places are starting to ban them. It may also be banned in some private places. We have heard of cell phone jammers being used in schools and cell phone jammers being used in prisons to disable cell phone signals and protect prison security. What about the conference room? Have you seen any examples of this? With people increasingly relying on cell phones, many companies are starting to install an adjustable device in the meeting room. The cell phone jammers will be held in the meeting. The meeting leader conducts the meeting properly without the ringtone intervening. opens and adjusts the disruption area in the conference room. This not only affects the normal use of the outside, but also provides the environment for the meeting.

If the ringing of a cell phone interrupts the speaker’s thinking at an important meeting, it will upset them and distract attendees from the meeting. The cellphone in the meeting room with important rings is rude behavior. Therefore, in many meetings, before the prompts begin, the phone will shut down or put into mute state. Many companies are not allowed to take cell phones with them while attending the meeting, visible on cell phones in the Internet age, the use of cell phones is regulated more and more clearly.

If you’re part of a conference, how do you feel when you hear your cell phone ring frequently during meetings? I think you will be as mad as I am, dissatisfied with this behavior, and even berate the owner of the phone. This is an unfortunate ending, not what we want to see. To avoid these unpleasant results, the conference room to use portable jammer is very important. There are many advantages to using in the meeting room, as you can see above, to prevent the uncivilized phenomenon from occurring. There is not only a ban on cell phone ring tones, but also a ban on cell phone use during the period.

If you’re a boss, you need to attend the meeting often. A cell phone rings or someone is looking at a cell phone in the meeting. Then you can prohibit the use of the cellphone by installing a cellphone signal jammer. It can now be bought in our store www.jammer-shop.com, which will make you more accessible and respected for the staff.

Pros and cons of mobile phone signal jammer

Nowadays, with the rapid development of science and technology, traditional mobile phones are becoming more and more intelligent, and they have become an important communication tool indispensable in people’s daily work and life. Of course, the negative effects caused by mobile phones are also immeasurable. Negative impacts in special scenarios and specific times have become new leak channels and new criminal methods, posing a threat to the security of confidential information. Therefore, it is urgent to strengthen the management and standardized use of mobile phone signal blockers.

Mobile phone signal jammers are mainly used in places where no mobile phone communication is required, such as in various examinations, office premises of confidential departments, gas stations, etc. Because of their easy installation and simple use, more and more companies use signal blocker. And the equipment signal is always in a relatively static state, which will not interfere with other electrical equipment, and has played a certain role in some special places.

GPS signal jammer

The mobile phone signal jammer is also called mobile communication jammer, mobile phone signal isolator, conference security device, etc.The signal jammer transmits a strong signal consistent with the frequency of the mobile phone’s downlink frequency band, and is tuned with the signal sent by the base station to the mobile phone, so that the base station sends to the mobile phone The downlink signal is deformed and cannot be recognized by the mobile phone, which interrupts the connection between the mobile phone and the base station. Simply put, its main function is to make the phone unable to use normally. Its essence is to implement electromagnetic interference to the wireless network on which mobile phone communication depends, so that the mobile phone cannot access the network, and thus cannot receive information from the mobile network, and cannot send information through the network.

However, with the promotion of signal jammers, it has also brought some adverse effects. The wide use of signal jammers will interfere with the normal use of surrounding residents, causing residents to use mobile phones without signals. If the shielding range is shortened, there will be a lot of It is also difficult to control the blind angle and blind zone, the shielding edge distance, and the long-term coverage is wide, the power will be large, and the radiation generated will also affect the human body. Therefore, the quality of a mobile phone signal shielding device depends not only on the The effective shielding degree of mobile phone communication signals, but also whether the radiation pollution produced by it meets the national electromagnetic radiation protection standards

Especially in government agencies, once the staff of the agency accidentally leaked the content of their work, they could easily be stolen by illegal elements. This is a very dangerous thing for agencies and agencies. In order to prevent such incidents from happening, government agencies will be equipped with mobile phone signal jammers or mobile phone signal shielding cabinets to avoid leaks.

Is the cell phone signal jammer harmful?

It is very interesting that the mobile phone, which is the “enemy” of the cell phone signal jammer, has also caused controversy about security at the beginning of its appearance. However, as people gradually understand the mobile phone, people finally accepted the mobile phone, and In less than ten years, mobile phones have become an indispensable necessity in our lives, and even because of the popularity of mobile phones, a new generation has been born: the thumb generation. This shows the popularity of mobile phones. In the history of human knowledge, the development of one aspect of contradictory things can predict the future of another aspect. Such examples are not uncommon. I think the development of mobile phones as the “enemy” of the mobile phone signal shielding system may be It can provide a blueprint for us to predict the industry picture of the mobile phone signal shielding system.

Finally, I want to tell a true story: when China was building the Daya Bay Nuclear Power Plant in Guangzhou in the 1990s, Hong Kong citizens were very resistant to the project because of the safety of nuclear power. In order to dispel the doubts of Hong Kong citizens, the chief engineer of the project I joked that kitchen knives are also problematic in safety. Kitchen knives can cut fingers inadvertently, and even be used as murder weapons by wicked people. But this does not prevent us from using kitchen knives and does not prevent China from becoming a great food country, because as long as we do our best, we can Can prevent these things from happening. This very superb joke at the time greatly eased the resistance of Hong Kong people to the Daya Bay Nuclear Power Plant and made a small contribution to the smooth start of the nuclear power project.

There is no doubt that technology is a double-edged sword. We all know that mobile phone signal jammers have a certain amount of radiation. In the current situation that there is no authority to define how much this radiation can harm people, what we should do is to start from a people-oriented perspective as much as possible and make good use of technology. Advantages, control and reduction of the disadvantages of science and technology, on the premise of ensuring the safety and health of people, to decide whether to widely use in daily life, not for the uncivilized behavior of a few people, and ignore or even affect the interests of most people .

Meticulously developed high-tech product MDPB-40C jammer

The MDPB-40C mobile phone signal jammer is a high-tech product that our factory adopts foreign advanced technology, aims at the continuous development of communication standards, and is carefully developed according to the actual situation of foreign mobile communications. It can be used in a radius of 10-25 meters (about 50-300 Square meters, the shielding range can be adjusted according to the required location) GSM/ CDMA/ AMPS/DCS/PHS/3G (WCDMA, TD-SCDMA and CDMA2000) and 4G mobile phone signals can be cut off. 2. The 4G wireless signal prevents the mobile phone from making and It can answer, and cannot send or receive text messages, but it will not interfere with the work of other electronic devices, thereby ensuring the safety of the required place. The mobile phone can be used without any damage to the human body after leaving the partition range.

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

For the shielding of the internal area of ​​the building, the distance between the residents (schools) and other public facilities in the area where the building is located should be considered, and the distance and signal strength of the surrounding communication rack base stations should also be referred to, so as not to affect the normal communication of mobile phone signals in the surrounding public facilities. , Our company selects MDPB-25W indoor host product for the shielding in the building to carry out the network shielding of the indoor antenna mode.

Will it affect WIFI when using cell phone signal jammer?

In our lives, we often use cell phone signal jammer, and when we use mobile phone signal jammers, it is inevitable that there will be such a question: Will using mobile phone signal jammers block wifi? Let’s learn about it with Jammer-mart:

buy signal jamming device

The shielding frequency band of mobile phone signal jammer is generally:

CDMA frequency band transmission frequency 869-894MHz

GSM frequency band transmission frequency 925-960MHz

DCS frequency band transmission frequency 1805-1880MHz

PHS frequency band transmission frequency 1900-1990MHz

WIFI transmission frequency 2400-2485MHZ

4G transmit frequency 2300-2390MHZ

4G transmit frequency 2555-2565MHZ

If the jammer contains 2400-2485MHZ, then 2.4G wifi will be shielded. If the jammer contains 5.8G shielding frequency band, it will shield 5.8G wifi frequency band. Generally, the jammer does not include 5.8G Wifi frequency band. Can not shield the 5.8G wifi frequency band.

School installs jammers to block students from texting

SPOKANE, Wash. – Frustrated by the continued distraction of cell phone texts and calls, a Spokane school invested in a device to block phones from work.

The main reason for this is that students cannot focus on their work during class but spend a large part of their time using cell phones and therefore always look for a tool that can block cell phone signals so that students can concentrate on their class can concentrate. The cell phone jammer is a good choice, it can quickly block the phone signal, turn it off when not in use, and the phone can restore the signal.

Mobile Phone Jammer

Mt. Spokane spent less than $ 100 buying a cell phone jammer online and was just completing a three-day trial period aimed at frustrating students writing in class.

“We just thought it was something we wanted to evaluate,” said director John Hook.

The Mead School District is working with the FCC to determine if the device is legal before it can be used again.

The jamming device was switched on during class time and switched off during passing times and the lunch break.

“We believe there are times during the school day when parents need access to students and students need access to family members, doctors and the like,” Hook said.

But class time is not one of them. Student policy requires students to have cell phones if they are turned off and kept out of sight during class; but not everyone obeyed.

4G jammer adopting new technology

Currently, 4G network signals are on the market. New technologies are needed in the world of innovation. I heard about 3G mobile phones a few years ago. Today, 4G signals are becoming more and more popular. We have developed jamming devices such as deterrents. This is possible due to the constant improvement of technology. Ideal for using 4G phone jammers to prevent unwanted calls when you are doing important work. Some products have a handheld design. You can carry it anywhere.

Jammer VS Bugs Who Will Win?

We have recently been able to read in all the newspapers about the scandal now called “Mafia Roma Capitale“. Mostly, some intrepid journalist wanted to venture, probably because he had been lucky enough to read some minutes, or who knows what “tip”, on the use by the alleged criminal organization, of appearing “jammers” and cards in the name of third parties , in order to divert the investigation.

Both the first, the so-called wireless jammer, are addressed as NOT working, for the diversion of investigations carried out by the authorities in charge. We obviously have no “paper” in hand, just as we have no “tip”, so we limit ourselves, as far as it can be reliable, to answer the question of greatest interest; how was it possible to intercept the subjects even when they had the jammer on?

gps wifi cell phone jammers

The answer is simpler and more obvious than you might think, already visiting and reading our previous news, specifically “Which Jammer to choose”, you can give an answer to everything, but we would like to clarify again, below we explain in detail:

To be able to secure an environment, it is NECESSARY TO HAVE MORE THAN ONE JAMMER and more.

The frequencies used by the signal are wide, there is NO portable signal jammer in the world capable of canceling them all. Conceptually, it is a bit like having a room with a hypothetical number of 10 doors, closing 1 or 2 does not preclude the opening of the remaining ones.

The pocket jammers, let’s talk about the best, inhibit the frequencies of cell phones and at most the 2.4GHz WiFi network or GPS. They leave the “doors” open for all VHF – UHF radio bugs, or perhaps high radio frequency bugs and why not, directional laser pointing or more simply bugs with direct recording to MicroSD, which, the latter two, cannot be inhibited with no jammer!

Moral of the story, the device purchased could NOT be sufficient to make a safe environment.
In order to make a safe environment, at least it must cover ALL VHF UHF frequencies, cell phones, high radios and other equipment such as white noise generators aimed at protecting conversations from any recorders and / or directional. This is the only technical explanation, the rest is just chatter from bars or the writings of “newsagents” paid for by third parties.

As in any survey, most of the wiretaps carried out are by telephone. The cards, even in the name of third parties, are NOT safe. There are various methods to be able to intercept them and charge the end user. The only secure systems are encrypted mobile phones, where conversations can NOT be listened to and neither appear on any printout.

This is not intended to be a “guide to the criminal”, but it seems more than appropriate to clarify and tell the truth about the facts.

Are Cell Phone Jammers the Next Big Thing?

A Philadelphia man was caught red-handed this week for using a mobile phone jammer to prevent fellow passengers on a public transit bus from using their cell phones.

“I guess I take the law into my own hands,” he told an NBC10 reporter about the illegal jammer, “and to be honest, I’m proud of it.”

Teresa Masterson, a writer on NBC10, first encountered the jammer on her morning commute and gave NBC investigators a lead.

A jammer that blocks radio frequencies isn’t just limited to blocking people

But while today’s news and the resulting internet outrage can only be felt by a single man, the practice of jamming cell phones is widespread in both New York and Washington DC. I spoke to two such “jammers” this morning about why they bought equipment that ranged from $ 40 to over $ 10,000 on sites like jammer-welt.com. Some boast a radius of just 15 feet, while others claim they are used in military vehicles and for counter-terrorism maneuvers.

“You’re the best thing ever,” says a New Jersey-to-New York commuter who lugs around a jammer every morning on his 40-minute ride on the New Jersey Transit. He doesn’t do it for the entire trip, he says, only when a fellow passenger speaks “too loudly” or “too long”. “It fits in your pocket – they even make shady packs of cigarettes. I would guess it’s effective for a 15 foot radius, possibly more,” he says.

“When I’ve used it, it’s to turn off a loud speaker on the train that is sitting near me.” He says he bought it online from a website that imports the equipment from China, where it’s legal, and when asked, told me that he never felt guilty about keeping his passengers from talking. “No fault,” he says, “just personal high fives.”

“I always have a grace period for calls,” says another jammer who takes the MARC train to Washington DC. The journey takes about 30 minutes. “If someone says,” Okay, well, I’ll be in the office in 10 minutes, then we can discuss it. “I’m not going to bother you. But if you talk about what you did last night and what kind of curtains you are getting for the house, then yes. Silenced.”

Does he feel guilty? As if it was causing a public grievance? Not as much. “People are mad and ranting on their cell phones all the time. But I feel like it gives me some control over what I believe is becoming an increasingly reckless society.

“I’m not a threat to public safety,” he says. “I don’t put anyone in danger more than anyone else in a subway without the reception of cells being compromised.”

jammer-welt promotes the sensible and legal use of cell phone jammers and correctly protects their legitimate rights and interests.
