A cell phone jammer is an electronic device that can obstruct the reception or transmission of cell phone signals by generating interference within the frequency bands used by mobile phones. By transmitting signals on the same radio frequencies as cell phones, the jammer disrupts the communication between the phone and the nearest cell phone tower, effectively rendering the phones within its vicinity unable to receive signals.

When contemplating the purchase of a cell phone jammer, it is advisable to take certain factors into consideration:

• What is the required range of coverage for the cell phone jammer?
• Are you seeking a small and inconspicuous cell phone jammer that can be conveniently carried in your pocket?

When it comes to reducing disturbances caused by people nearby in public spaces or silencing the use of cell phones within your business or educational institution, cell phone jammers provide numerous advantages. However, it is vital to conduct thorough research in advance to ensure the purchase of a signal jammer that will effectively meet your specific requirements.

When searching for cell phone jammers for sale, you should take the following into consideration…

1. What is the length of time the vendor has been in business?
2. Is the vendor offering a range of products, or are they exclusively selling signal jammers?
3. What is the desired range of coverage for the cell phone jammer?
4. Are you searching for a discreet (handheld) cell phone jamming device that can fit easily into your pocket?

Effective measures should be taken to eliminate potential safety hazards and jammer gps buy ensure the safety of gas stations.On the one hand, the customer does not know the safety management regulations of the gas station, and believes that it is unnecessary for the gas station employees to let them use their mobile phones in the gas station, which is prone to rebellious psychology.

One of the more difficult to manage is the prohibition of customers using mobile phone calls in gas stations mobile signal jammer.The exercise of any right is limited and must not prejudice the rights of others or the public interest.The freedom of communication and speech that citizens enjoy in accordance with the Constitution and the law shall not exceed their due scope.As we all know, gas stations dealing with flammable and explosive materials are high-risk industries, and “safety first” is the most basic requirement for gas stations.Common safety measures at gas stations mainly include turning off motorcycles to refuel, gas station employees must wear anti-static clothing to work, prohibiting open flames and using mobile phone calls in gas stations, and not refueling in plastic buckets, etc.

Because refueling and gas stations are now generally controlled by computers, high-intensity mobile phone signals will cause induction with computer equipment, and the instantaneous electronic friction between the two may ignite fuel vapor and cause an explosion.Therefore, it is recommended to connect the power of the shield to the battery of the car as much as possible to ensure that the device can work continuously.In recent years, with the rapid development of mobile phones, it is not uncommon for students to use mobile phones to affect their life and learning.It is still one or two o’clock, so in order to prevent students from playing mobile phones in the middle of the night and give themselves a better rest, many schools have to choose to install wifi jammer in their dormitories.

On the other hand, the customer knew that he could not use the mobile phone in the gas station, but he was lucky, and one-sidedly believed that the accident would not happen when he was using the mobile phone, so he did not listen to the persuasion of the gas station staff and went his own way.Strictly speaking, vehicle anti-monitoring and anti-tracking is a comprehensive professional discipline.It integrates communication engineering, radio technology, electromagnetic research, information science, network security, psychology and other disciplines.If the car turns off halfway, the jammer gps will definitely be powered off, then the location information of the car will be exposed again.

As long as the RF spark lasts for more than one microsecond and the energy is greater than 6 milliwatts, it will ignite the methane-air mixture.So is it enough to put a high-power mobile signal jammer? Is every room in the school dormitory like a school exam room? Actually, how to select and install it is explained below.The cell phone signal jammer gps in the school dormitory are mainly used at noon and evening when students are resting.The wifi jammer gps can be big or small, and there are many channels in any frequency band of mobile communication.Obviously, the school’s behavior is mild and does not affect students’ freedom of communication and expression.

Some students often use their mobile phones to surf the Internet in bed, and some even use their mobile phones to surf the Internet in the middle of the night.At the same time, in order to make the communication signal clearer, the frequency of mobile phone use is very high, and the transmission power is relatively strong.Since gasoline is a volatile substance, in the combustible danger area formed by the leakage of oil and gas tanks and natural gas pipelines, the radio frequency sparks generated by mobile phones can easily cause explosions and lead to disasters.When RF current circulates between metal conductors, RF sparks will be generated in case of corrosion or poor contact.

This type of jammer gps can basically be powered by the cigarette lighter, so after being installed in the car, it must be ensured that the jammer GSM is always in working state.At present, the main way for gas stations to prohibit customers from using mobile phone calls at gas stations is to persuade, but sometimes the effect of persuasion is not ideal.The current required to ignite the fuel gas is very small, and the static current generated by the mobile phone in the working state can completely reach this limit.Although it meets the national standard, it still poses a serious threat to refueling and gas stations.

That is to say, there is no need to shield the mobile phone signal 24 hours a day, so the shielding device of the ordinary power supply such as the external adapter is also optional.As a radio communication tool, the mobile phone emits radio waves, which can induce radio frequency currents in the antenna that receives the radio.Why can’t you make phone calls in the gas station? Some people think that it is alarmist that a mobile phone can cause an explosion at a gas station, and they have never heard of an explosion caused by a mobile phone.First of all, people have misunderstandings about the safety hazards caused by using mobile phones in gas stations.

Teacher suspended for blocking students’ cellphones

LAND O’ LAKES, Fla. –The act of a science teacher in Florida using a signal jammers to prevent his students from using their cellphones during class has resulted in his suspension.

WTSP-TV, the CBS Tampa affiliate, highlighted Dean Liptak’s efforts to engage students in their lessons by diverting their attention away from their phones.

Liptak’s five-day, unpaid suspension was officially sanctioned by the school board members in Pasco County on Tuesday. Liptak did not raise any objections to the decision.

According to officials, Liptak utilized the phone jammer in his Fivay High School classroom, commencing on March 31 and concluding on April 2.

In his conversation with the school district investigator, he made it clear that he had no intention of causing any disruptions. He explained that he believed the jammers were permissible as long as they were not intended for any malicious purposes.

According to WTSP, the district has acknowledged that Verizon made the choice not to pursue charges against him.

Superintendent Kurt Browning conveyed his concerns in a reprimand letter, pointing out that Liptak’s actions of signal jamming had the potential to violate federal law and create interference for individuals attempting to contact 911 during emergencies.

“Verizon had come to the school saying someone had a jamming device, because the cell phone service was being interrupted in the area,” WTSP quotew Pasco County School District spokesperson Linda Cobbe as saying.

It has been stated by Cobbe that Liptak’s jamming device effectively hindered communication to the cell tower situated on the Fivay High campus.

It is high time that steering wheels were equipped with cellphone signal jammers.

In California and a minimum of twelve other states, it is considered unlawful to operate a vehicle while holding a cellphone. Despite the clear prohibition, many individuals still choose to disregard this law.

Without fail, we encounter thoughtless and self-entitled individuals on a daily basis, who pose a danger to themselves and others by engaging in conversations or texting while driving.

In motor vehicle accidents last year, a staggering 37,133 fatalities were recorded by the National Highway Traffic Safety Administration, with distracted drivers accounting for more than 3,000 of these deaths. Moreover, each year, a significant number of individuals sustain injuries due to drivers being distracted and not paying attention to the road.

In order to gauge the perspective of car manufacturers, I reached out to the Alliance of Automobile Manufacturers, an industry association. According to Bryan Goodman, a representative of the organization, automakers approach this issue with great seriousness.

“We can all agree that hands on the wheel and eyes on the road continue to be critical to safe driving,” he said, adding that cellphones “were never designed to be used while driving.”

The statistics speak for themselves: distracted driving fatalities exceed the number of lives lost in the Sept. 11 terrorist attacks, underscoring the urgent need to address this grave public-safety concern.

The rise of the Internet of Things has led to an increasing demand for location services. According to certain institutions, it is predicted that 60% of Internet of Things devices will rely on geographical location data. Outdoor positioning, in particular, is expected to be a significant market that should not be overlooked.

The GNSS (Global Navigation Satellite System) is a highly esteemed international club comprising of merely four members, which garners the interest of global leaders and the scrutiny of numerous esteemed scientists and engineers. These four members include the GPS of the United States, GALILEO Galileo of Europe, GLONASS of Russia, and Beidou COMPASS of China.

There are four prominent satellite navigation systems worldwide, including China’s Beidou satellite navigation system, the United States Global Positioning System (GPS), the European Union’s Galileo satellite system (GALILEO), and Russia’s GLONASS satellite system (GLONASS). These four systems are acknowledged as suppliers by the United Nations Satellite Navigation Committee.

China Beidou is a recent addition, yet it stands out as the most dynamic member in terms of development. What exactly is Beidou and how does it influence our daily lives? This intriguing subject has garnered significant attention. Numerous scholarly publications delve into the intricacies of Beidou; however, these professional articles often employ jargon that may deter the interest of the general public.

Small GPS signal blockers great use

Across the world, the GPS satellite positioning system stands as the most commonly employed satellite positioning system. It facilitates vehicle tracking, route navigation, information inquiry, traffic command, emergency assistance, and other crucial functions. Although the GPS satellite positioning system has significantly improved convenience in our lives, it has also introduced certain troubles that even pose a threat to individual safety.

As an example, mortgage car companies provide financial aid to the original owner, temporarily gaining control of the car. To prevent any clandestine attempts by the original owner to reclaim the vehicle, these companies invest in GPS shields. These shields are installed in the vehicle’s parking lot and on the car itself, rendering the original owner unable to locate the vehicle. This precautionary measure ensures the protection of the property.

As the GPS locator market continues to expand, individuals who wish to avoid being tracked by GPS signals are increasingly searching for GPS signal blockers. These blockers are designed to prevent signal tracking, but their actual efficacy in achieving this remains uncertain.

Most GPS locators can be effectively shielded by gps blocker. The use of blockers disrupts the normal functioning of the GPS locator, preventing complete data transmission to the locator monitoring platform. Similar to mobile phones, GPS locators require the insertion of a mobile phone card or an Internet of Things card to retrieve data. Therefore, as long as the GPS signal blocker can obstruct the signal transmission of the mobile phone card, it can also block the GPS locator.

After the new wipe that made its way into Escape from tarkov on 28th December, players have been trying to grind in the game and have been completing quests given by traders to reap rewards, experience points, and reputation. Broadcast – Part 1 Quest is the starting point for a series of quests under trader Sergey Arsenyevich Samoylov, known by his alias “Mechanic.” Once you finish this quest, you will have the opportunity to finish the other Broadcast quests and also do other ones offered by Mechanic. This particular quest happens on Lighthouse, the eighth location that was added to the game.

When you take up this quest from the Mechanic, he says that he does not really understand anything in life and that he heard something about a live broadcast in the city somewhere. He adds, “They say that someone is performing surgeries and filming it on their camera. I’d understand if it was an actually good willed doctor helping people. I would even understand if there was an organ trade, although that in itself is disgusting. But tell me, why stream this? Is this a kink for some perverted oligarchs? I honestly don’t have an answer. But I do know that this broadcast must be shut down. Can you put a cell phone blocker near them?”

The Broadcast – Part 1 quest objectives are:

• Locate the hidden recording studio on Lighthouse
• Place a Signal Jammer inside the studio

For this task, you will need the Operating Room key. This can be found in the pockets and bags of Scavs as well as in jackets. However, that being said, it is a rare key. It can sometimes also be bought from the flea market.

Firstly, you will have to go to the Water Treatment Plant on Lighthouse for this quest and enter Building 1. Your PMC will start just outside Building 1 and as you enter it, you will have to hug the right-side wall and walk all the way straight till you find a door. This door leads you to the Operating Room where you will use the key.

Once you enter the room, you will immediately be prompted to plant the signal jammers anywhere in the room. It is a 10-second timer and if you happen to die while planting, you will have to start from scratch. However, the good news is, if you successfully plant the jammer, the Broadcast – Part 1 quest will get auto completed and you will not have to survive an extract from the raid.

Dad Uses Signal Jammer to Stop His Kids from Going Online

Due to his unawareness, a resident living in the southwestern French town of Messanges might face a prison term of six months for inadvertently disabling telephony and mobile internet services in his local area using a signal jammers.

Surprisingly enough, his actions were not fueled by malice. His only intention was to restrict his teenage kids from using their mobile devices to go online once it was time to sleep.

According to the French planning and radio frequency management agency (ANFR), a complaint of an unusual nature was filed by a local mobile phone operator. The complaint highlighted the inconvenience faced by the residents of Messanges, who were unable to utilize their cellular and mobile internet services from before midnight until 3 AM every week.

The French planning and radio frequency management agency (ANFR) has reported an atypical complaint lodged by a local mobile phone operator. The complaint stated that the residents of Messanges faced an inconvenience as their cellular and mobile internet services were unavailable from just before midnight until 3 AM every day of the week.

In light of their investigation, the ANFR has established that a mobile phone jammer, a device prohibited in many European countries, including France, was responsible for interfering with radio frequencies in the area.

Around 1:30 am, a technician skillfully traced the source of the signal to a residence nestled in the coastal town. The following day, investigators, accompanied by police officers, proceeded to knock on the man’s door. Without any delay, the individual immediately admitted to utilizing a multi-band jammer.

The ANFR clarified that the father of the family had taken the step of installing a jammer to discourage his teenagers from using their smartphones to access the internet late at night. This decision was prompted by the children’s addiction to social networks and various applications. After consulting online forums, the father concluded that a jammer would be the optimal solution to address his kids’ excessive screen time.

Version 4: Besides demanding the owner to switch off the jamming wifi and refrain from using it, the ANFR agent emphasized the need to comply with the regulatory framework, as stated by the agency.

The inclination of parents to buy cell phones for their children and teenagers is understandable. The underlying reason is to ensure that their children remain connected to them. By having a phone, children have the convenience of contacting their parents at any given time, whether it is to arrange for a pick-up from school or to seek immediate assistance in case of an emergency where their parents’ presence is needed.

Nonetheless, it is important to be aware of certain matters that come with buying a cell phone for your child. These matters hold significant importance and should be recognized by numerous parents, as they involve not only the potential risks associated with cell phone use but also behavioral issues. Prior to giving your child a mobile phone, it is crucial to observe their behavior diligently.

Addiction is problematic

The captivating technological features of cell phones easily entice children and teenagers, leading them towards addiction. Whether it’s the constant texting, browsing social media, or engaging in non-stop conversations with friends, these activities consume their time and attention. Disturbingly, the prevalence of cell phone addiction is on the rise, exacerbating the situation.

The detrimental effects of excessive cell phone usage can lead individuals to disregard their educational obligations and other crucial aspects of life. This is evident as students persistently utilize their phones to access social media platforms like Facebook or Twitter, engaging in conversations rather than prioritizing their studies and other course-related activities.

Misconduct

The worst part about cell phones for kids is that many of them can engage in extremely inappropriate and potentially dangerous behaviors. Questions about bullying and how easily it spreads online have persisted for years. With mobile devices, people can easily be bullied. Children and teenagers can send each other angry messages non-stop. They may even make it harder for other children to enjoy their lives, or they may even ruin their own lives.

Additionally, children may send inappropriate images and text to others. They may send or receive dirty and possibly sexually explicit messages. They may not know how inappropriate these things are.

The pictures children take of themselves can also be quite disturbing. Children may take photos of themselves without clothes and send them to others. This can be harmful because children expose their bodies to others who want to see them. This is a serious threat and not many children realize what they may sometimes encounter.

How teens and parents can deal with screen time and device distractions

54% of U.S. teens say they spend too much time on their phones, and two-thirds of parents are concerned about their children’s screen time.

Parents are also concerned about the impact of screen time on their children, a separate survey showed. About two-thirds of parents said they were concerned about their children spending too much time in front of screens, and 57% reported setting screen time limits for their children in some way.

Meanwhile, some parents of teens admit they too struggle with the lure of screens: 36% say they themselves spend too much time on their phones. 51% of teens said they often or sometimes find their phones distracting them when trying to talk to their parents or caregivers.

With the rapid development of mobile communication technology and the popularization of smart devices such as smartphones and tablets, students’ use of smartphones has reached the level of one for every student. In the past two years, due to the epidemic, students’ use of smartphones has also increased. Come more and more. It is impossible to learn school class knowledge through online classes on mobile phones. Although the school has repeatedly banned students from bringing mobile phones to campus, some students still bring mobile phones to campus. Schools face many challenges in managing smartphones:

• Students use mobile phones to play games and chat online, and even adolescent children browse unhealthy content online, which seriously affects physical and mental health;
• Students do not sleep at night after school, cannot concentrate in class the next day, and easily fall asleep in class, etc., resulting in serious deterioration in academic performance;
• Use mobile phones and other devices to cheat in exams, etc.

Based on the current situation, what we can do is:

Parents should increase the time for interaction and communication with their children, pay more attention to their children’s life and study, and take their children for outdoor sports. This will reduce the time children spend playing at home when they have nothing to do, and will also help cultivate parent-child relationships.

1. Guide children to play some educational games or learning software to make education interesting and emphasize that the Internet is a learning tool, not a toy.
2. Control the time children play games: Use a cell phone jammer to properly control the Wi-Fi network signal of the mobile phone so that students’ mobile phones cannot play online games within a certain period of time. Reduce conflicts between children and parents during the communication process.
3. Jamming mobile phones can be installed in school classrooms. Mobile phone wifi jammer can be turned on during class to block mobile phone signals in the classroom, and mobile phone signals can be restored during breaks.
4. The dormitory can be equipped with a mobile phone signal jammer. After turning off the lights at night, turn on the mobile phone signal jammer to restore the mobile phone signal late at night. Use cell phone signal jammer wisely.

Cell phone jammers find great relevance in classrooms, making them highly recommended. The pervasive use of cell phones in educational settings has become a matter of utmost concern, with teachers and administrators expressing worry about the detrimental impact on students’ focus and the disruption it causes to the overall learning environment.The presence of cell phones in the classroom allows students to cheat by utilizing them to look up information or communicate answers with their peers through text messaging.

Why do classrooms need cell phone jammer?

The use of mobile phones by students in the classroom often leads to their inadvertent neglect of crucial information being imparted by their teachers.

To maintain the integrity of significant examinations, it is imperative to adopt measures that prevent students from exchanging answers or, more seriously, from procuring exam solutions. By doing so, we can ensure the avoidance of incorrect and unjust test outcomes.

In select classes of utmost importance, teachers take precautions to prevent students from sharing the knowledge they acquire with third parties, thus effectively averting any possibility of information leakage.

What kind of disruptors are needed in the classroom?

The antenna is seamlessly integrated into the device, eliminating the need for any installation or removal procedures. Its user-friendly functionality and exceptional concealment make it incredibly easy to use.

Equipped with a remote control, you possess the capability to manage the jammer’s operation at your discretion. For instance, you can activate the blocking feature towards the end of an exam, when certain students may engage in dishonest behavior. Subsequently, you can immediately deactivate the wifi jammer using the remote control after the test concludes.

How to use jammers safely in the classroom?

In order to use it legally within the designated area and during the specified time, it is necessary to apply to the school safety director in advance and report to the FCC government. Once authorization is obtained, you may proceed with its usage.

Employ low-power jammers to counter the negative impact of excessive power on signals outside the classroom premises. Although it may only partially block the mobile phone signal, prioritizing safety is crucial, as no solution can guarantee absolute accuracy.

By utilizing a jammer that possesses a relatively inconspicuous design rather than an external antenna, it becomes effortless to capture the attention of students. In numerous movies and TV series, the signal jammer showcased often feature multiple external antennas, thereby effortlessly arousing the interest of students.

What measures can be taken to block the signal of children’s mobile phones and supervise their internet usage time?

It is crucial to shield children from mobile phone signals. Since birth, children are increasingly exposed to various electronic products, which can have adverse effects on their growth and development. Therefore, it is essential for us to promptly take steps to keep children away from mobile phones.

Due to the profound impact of the new coronavirus outbreak, many children have become accustomed to using mobile phones and playing online games on computers while staying at home. The utilization of a signal jammer can assist children in gradually breaking their internet addiction and gaining better control over their online activities. Simultaneously, adults can reduce their own mobile phone usage, allowing for increased interaction with their children and fostering a more contented family atmosphere. This, in turn, contributes to an improved family happiness index.

Method/Step 1: Restrict children’s mobile phone access to the Internet in the router

Through the utilization of security settings, all current routers offer the functionality to filter the MAC address of mobile phones, enabling the prohibition of Internet access for children’s devices.The router can be employed to limit children’s internet access in terms of time duration and internet speed, among other features, if you are more flexible. This feature is commonly found in most up-to-date routers. By restricting the internet speed, children will only be able to browse information using their mobile phones, while being unable to play games.

Method/Step 2: Use a signal jammer

Wireless networks have undoubtedly made Internet access more convenient for individuals, but the challenges they pose should not be underestimated. It is not just a matter of network accessibility; network security is equally important.In an effort to maintain a high-quality network environment, cell phone jammer are strategically placed in various locations to prevent excessive network usage. This equipment has gained significant traction in countries and regions across the globe. Schools, prisons, libraries, reading rooms, and gas stations are prominent instances where it is commonly employed.

Under what circumstances does a mobile phone signal jammer have poor shielding effect?

What circumstances lead to a mobile phone signal jammer’s ineffective shielding? In what specific environment can a mobile phone signal jammer be successfully implemented to achieve optimal signal disruption?The impact or lack thereof of mobile phone wifi jammer
in certain areas can be attributed to factors such as the surrounding environment, installation position, distance, and the quantity of jammers employed.

1. Due to the lack of data analysis, plane survey, shielding coverage plan, and other necessary work during the early stage, the blind installation resulted in no impact and a poor shielding effect. To avoid such issues, it is highly recommended to contact professional shielding customer service before installing the shielding device. They can provide valuable assistance and guidance. Moreover, it is advisable to seek professional installation advice before purchasing a shield suitable for use in locations that require shielding.

WiFi is transmitted in many segments. Without testing or checking the professional frequency band technical parameters given by the manufacturer, it cannot be completely shielded. WiFi is divided into three segments (2.4G+5.2G+5.8G) with a bandwidth of several hundred megabits. This is why many customers say There is a WiFi signal shield, but when used on-site, you can still connect to WiFi and watch videos online normally.

2. The requirements for installation height are not fulfilled, and the installation position is deemed improper due to obstructions. Moreover, the signal is blocked as a result of using partition walls.

3. The installation of mobile phone signal jammers can be affected by environmental factors, leading to shielding failure. This is particularly evident when intelligent base stations, operating at power levels above 200 watts, are located within a distance of 200-500 meters from the jammer’s location.In case of interference at the base station, it will automatically raise the transmission power, switch to a channel with a weaker interference signal, and have the freedom to switch between channels. Mobile phone signal amplifiers are commonly placed on the ceiling of locations where customers install mobile phone signal jammers.Concurrent usage of the jammer and amplifier leads to a deterioration in the jammer’s ability to cancel out signals.

4. Choosing the wrong jammers can lead to their malfunction. The selection of jammers should be based on the specific locations where they will be used. For instance, prisons and detention centers need to assess the completeness of channel shielding and the ability to operate continuously throughout the year. Medium-power mobile phone signal jammers are commonly employed in prison buildings.In order to provide additional protection in playgrounds, jammers are used for supplementary shielding, while high-power directional shielding is employed in the release square to completely block the prison signal. However, the widespread use of mobile phone signal jammers in prisons can result in management difficulties and higher maintenance expenses. To address this issue, the possibility of utilizing remote control software for batch management is being considered.School examination rooms and conference rooms are generally open for a short period of several hours. They do not have high requirements on machine performance, but high requirements on shielding effect. For large areas, low power is recommended, or the power is insufficient and shielding cannot be performed. Directional shielding is required and external shielding is used. Problems such as insufficient full coverage lead to poor shielding effect and intermittent shielding effect when installing a mobile phone signal jammer. Choosing a low-power jammer in a large area or too high a power in a small area will result in improper purchase and poor shielding effect.

Individuals who have undergone extensive examinations are well-acquainted with this phenomenon, as it is frequently mentioned prior to the exam that mobile phone signal jammers might be deployed within the examination venue. In certain instances, the examination rooms themselves explicitly notify candidates through the integrated speakers, ensuring that they are aware of the presence of mobile phone signal jammers within the examination premises.

The primary purpose of a mobile phone signal jammer is to disrupt or block the transmission of signals between mobile devices and cellular towers.

Mobile phone signal jammers are employed to disrupt mobile phone calls and network transmission within a specific vicinity. Typically, these devices find application at college entrance examination venues to deter certain students from surreptitiously carrying advanced electronic gadgets into the examination room for cheating purposes. However, it should be noted that the primary objective of a cell phone signal jammer extends beyond this particular scenario.

To guarantee the security of crucial locations and positions, numerous confidential establishments will deploy mobile phone signal jammers in select sensitive areas, adhering to pertinent management regulations and requirements. These jammers effectively disrupt the transmission and reception of mobile phone signals, including 2G, 3G, 4G, 5G, WiFi, Bluetooth, and other signals, within a specific range. Consequently, communication connections and data transmission become unattainable, effectively enforcing a mandatory ban.

Mobile phone signal jammers possess the capability to obstruct mobile phone signals. These devices are commonly employed in examination rooms to deter candidates from engaging in cheating activities. Due to their remarkable shielding effectiveness, mobile phone signal jammers have raised concerns among individuals regarding their potential impact on base station signals within the vicinity or surrounding communities.

A mobile phone signal blocker operates by emitting targeted signals to disrupt, obstruct, or impede the connection between a mobile phone and the base station. As a result, the mobile phone is unable to receive any signal or access network services. Additionally, the text messages transmitted and received by the mobile phone will be distorted, rendering the original content unrecognizable.

An installation plan for the outdoor signal jammer is being devised.

In order to install the signal jammer outdoors, it is crucial to implement waterproofing and lightning protection measures. It is generally advised to opt for a dedicated installation box designed specifically for signal jammers. This installation box is constructed using flame-retardant plastic and can be extended with additional meters on both sides. It features a window-type ventilation position to enhance heat dissipation. The antenna of the mobile phone jammer protrudes from the top of the box through a sealed hole using hot melt glue. At the bottom of the box, there are power input holes and diversion holes to prevent water accumulation.

The signal jammer’s host is positioned at the top of the box, while the antenna protrudes from it. It is crucial for the antenna to extend out of the box to maintain the optimal shielding effect. As for the power adapter, it should be placed in the lower and middle section of the box.

It is imperative to implement lightning protection measures when installing the signal jammer (along with the installation box) outdoors, for instance, on the exterior wall of a building. This precaution becomes even more crucial in areas prone to thunderstorms. Extra attention should be given to ensure safety in such circumstances.

The installation of a lightning rod on the shield is the actual measure taken for lightning protection. In case a ready-made lightning rod is not available for purchase, one can create their own lightning rod using the following method.

You have the option to select 3-4 steel bars ranging from 5-10mm in diameter and 50cm in length. One end of each bar is sharpened to resemble a needle, while the other end is welded together to create a “Y” shape. The welded end is then connected to a steel bar with a diameter of 2-3mm. The ground, where the iron wire is protected by PVC pipes, is connected to one end of the iron wire. This iron wire is further connected to an iron strip. Typically, the iron strip measures around 50-100cm in length and 2-5cm in width, and is driven deep into the ground. In case iron strips are not readily available, you can substitute them with 10mm steel bars.

It is imperative to install the lightning rod at a height of 30-50cm above the antenna of the mobile phone signal jammer. To avoid any interference, it is crucial that the lightning rod, including the grounded steel wire, does not come into contact with either the mobile phone jammer or the installation box. The appropriate distance between them should be maintained.
