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.

A plea of not guilty was entered by Trenton Lisak, a Mobile resident, on June 15, 2023, after being charged with interfering with emergency communications and possessing drugs.

He is accused by the prosecution of utilizing costly and highly sophisticated equipment from an apartment at the Tower on Ryan Park. Mobile County 911 officials report that this action effectively crippled communications in downtown Mobile on June 6 and led to disturbances throughout the rest of the week.

July 19th has been designated by the judge as the date for Lisak’s preliminary hearing.

ORIGINAL STORY:

According to law enforcement authorities, costly and highly sophisticated black market jamming device caused interference in police and emergency services transmissions for a significant period of time last week.

The police arrested Trenton Edward Lisak on Saturday for interfering with public safety communication, a Class C felony that can lead to imprisonment for a period of one to ten years. He has also been charged with drug possession. According to prosecutors, the FBI is conducting an investigation into the matter.

Monday witnessed Mobile County District Attorney Keith Blackwood describing the charge as peculiar. He underlined its significant nature, emphasizing the indispensable requirement for law enforcement and first responders to possess the means to communicate effectively, not only within downtown areas but also in any given place.

How peculiar!

Blackwood acknowledged that this was a first-time occurrence for him. He couldn’t recall any other case where such an event had taken place, particularly not on this scale. The considerable amount of equipment involved made it a highly significant incident.

Lisak’s arrest record comprises charges related to theft, breaking into cars, possession of a forged instrument, and acts of criminal mischief.

Mobile County District Judge Jennifer Wright has established a bail amount of $15,000, which aligns with the highest recommended bail for this particular offense. Furthermore, she has mandated that 10 percent of the bail be paid in cash. Additionally, Judge Wright has imposed an extra $5,000 bail specifically for the drug charge.

Additionally, the judge implemented a curfew that would be in effect from 8 p.m. to 8 a.m. and issued a directive for Lisak, aged 31, to maintain a distance from the Tower at Ryan Park located downtown. This residential complex is where the equipment, which disrupted the communication systems of all 57 law enforcement, fire, and emergency medical agencies within the Mobile County Communications District, was discovered.

According to Lisak’s booking information, the address mentioned is his registered home address. However, the prosecutor informed the judge that investigators have expressed skepticism regarding his actual residency at that particular location.

Robert Jackson, a district administrator, characterized it as “an exceptionally advanced apparatus arranged within the apartment, specifically engineered to disrupt our signal.”

Jackson added, “In order to locate it, we had to make adjustments to our instruments.”

In a statement to FOX10 News, Charlie McNichol, the director of the 911 system, revealed that the interference resulted in a complete cessation of communications for a day during the previous week.

During the Tuesday of the previous week, it gave rise to significant issues in the downtown area,” he mentioned. “To be more precise, the alarms were emanating from our tower site situated at Government Plaza. Consequently, the initial responders faced serious difficulties in their communication efforts.”

It remains unclear what the motive may have been, officials said. Blackwood said he does not know what the defendant was planning, or where he got the equipment.

McNichol said he does not know if Lisak just enjoys watching chaos or if he had something more sinister planned and attempted to jam communications as part of that.

“This individual had some cell phone jamming equipment that you buy on the black market,” he said. “It’s illegal to even possess it. And that’s what was causing the problems.”

Mobile phone signal jammers are used in many places, but they cannot be used immediately after installation. We still need to go through certain testing and acceptance to determine its effectiveness and ensure its effectiveness.

It is very important to ensure whether the mobile phone signal jammers can truly effectively block mobile phone signals. When purchasing a mobile phone signal jammer, testing is a very important step.

1. Test the blocking distance of the mobile phone signal jammer. Don’t just try it with one or two network mobile phones. The mobile phone networks used are different, especially the 4G mobile phone network. The 4G network uses a broadband high-speed transmission method. If the mobile phone If the signal cellphone jammer is not powerful enough, it may not be able to block 4G;
2. It is necessary to find all the mobile phones in the current network of mobile communication providers before testing. Make sure that each mobile phone network can meet the needs of at least one classroom to be considered successful. After turning on the phone to test the shielding effect, be sure to ensure that there is no signal on the mobile phone within half an hour and no time appears. sometimes not;
3. Another important point is that if it is a mobile phone wireless signal jammer with a metal shell, touch the front and rear sides of the fuselage with your hands after 1 hour after turning it on. If the temperature is moderate and not hot, there will be no problem. If it is very hot, it will not pass, because the machine continues to heat up. It will cause the power of the mask to attenuate, make it unable to work stably, and easily cause burns.

The main functions of the four major signal frequency bands used by drones

• 1. 2.4GHz frequency band
• The 2.4GHz frequency band is one of the more common frequency bands used in drones. It is a type of radio frequency band used by drones and is mainly used for WiFi and Bluetooth communications. This frequency band has a wider coverage and a faster transmission rate, so it is widely used in remote control and image transmission of drones.
• 2. 5.8GHz frequency band
• The 5.8GHz frequency band is one of the most common frequency bands in drones. It is also used in WiFi and Bluetooth communications, and is also widely used in drone image transmission systems. Compared with the 2.4GHz band, the transmission rate of 5.8GHz is faster, but the coverage range is relatively small.
• 3. GPS satellite signal frequency band-1.5G frequency band
• The GPS satellite signal frequency band is a type of frequency band used for drone positioning. It can accurately locate the position of the drone, thereby enabling flight path planning and tracking. GPS satellite signals are also one of the keys for UAVs to achieve autonomous flight and formation control.
• 4. Remote control signal frequency band-900 frequency band
• The remote control signal frequency band is a type of radio frequency band used for remote control of drones. It connects the drone flight controller to the remote controller to achieve remote control of the drone within a certain range. This frequency band has a smaller application range, but it plays an important role in remote control of drones.
