jammer

The classroom is an ideal setting where the implementation of cell phone jammer is strongly recommended. Over the past few years, the proliferation of cell phone usage in educational institutions has posed a major challenge, leading to concerns among educators and administrators regarding the potential distractions and disturbances it may cause to the learning environment.The act of using cell phones in the classroom enables students to cheat by either searching for information or sharing answers through text messages.

Why do classrooms need cell phone jammers?

1. Mobile phones have become a prevalent source of distraction for students in the classroom, causing them to inadvertently overlook significant information that is being taught by their teachers.


2. To safeguard the authenticity of vital examinations, it is crucial to establish measures that discourage students from sharing answers or, more seriously, resorting to purchasing exam solutions. By doing so, we can mitigate the occurrence of erroneous and unjust test outcomes.


3. In order to prevent the unauthorized sharing of vital information, teachers in certain significant classes take measures to ensure that students do not directly transmit it to third parties, thereby mitigating the risk of information leakage.

What kind of disruptors are needed in the classroom?

Save time on antenna installation and removal as the device comes equipped with a built-in antenna. Its user-friendly nature and excellent concealment make it effortlessly usable.

Equipped with a remote control, you hold the power to oversee the functioning of the jammer at any given moment. For instance, you can activate the blocking feature towards the end of an exam, when certain students may resort to cheating. Subsequently, you can swiftly disable wifi jammer using the remote control after the test concludes.

How to use jammers safely in the classroom?

• It is essential to apply in advance to the school safety director and promptly report to the FCC government. Upon receiving authorization, you may legally utilize it within the designated area and during the specified time period.


• Opt for low-power jammers to prevent the disruption caused by excessive power on signals outside the classroom environment. Although it may only partially hinder the mobile phone signal, it is imperative to prioritize safety, acknowledging that no solution can provide absolute accuracy.


• Opting for a signal jammer with a relatively inconspicuous shape instead of an external antenna can effortlessly captivate students' attention. In numerous movies and TV series, the jammers portrayed often come equipped with multiple external antennas, which can effortlessly pique the interest of students.

How can one prevent children from accessing the internet on their mobile phones and control the duration of their usage?

Blocking children's mobile phone signals is a necessary step to protect their well-being. Since birth, children are constantly surrounded by electronic gadgets, which can negatively impact their growth and development. Hence, it is essential for us to take prompt action in order to safeguard children from the harmful effects of mobile phones.

In light of the new coronavirus pandemic, a considerable number of children have developed a habit of spending excessive time on mobile phones and playing online games on computers. Employing a signal jammer can aid children in gradually overcoming their internet addiction and gaining better control over their online activities. Additionally, adults can reduce their own mobile phone usage, allowing for increased engagement with their children and fostering a more harmonious family environment. Ultimately, this contributes to an improved family happiness index.

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

By utilizing the security settings, all modern routers possess the capability to filter the MAC address of mobile phones, effectively preventing children's mobile devices from connecting to the Internet.By leveraging the router's capabilities, individuals with greater flexibility can effectively control children's internet usage by setting limitations on both access time and internet speed. This feature is commonly available in contemporary routers. Through the restriction of internet speed, children will only be able to utilize their mobile phones for informational purposes, while being unable to indulge in gaming activities.

Method/Step 2: Use a signal jammer

The advent of wireless networks has undeniably simplified Internet accessibility for individuals, yet the associated issues cannot be overlooked. It is not solely a question of network accessibility, but also a matter of ensuring network security.Signal jammers are employed in various locations to uphold a favorable network environment by deterring excessive network usage. This equipment has found extensive utilization across different countries and regions globally. Schools, prisons, libraries, reading rooms, and gas stations exemplify the typical settings where it is commonly deployed.

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

1. In which situations does a cell phone jammer exhibit subpar shielding capabilities? In what specific environment can a mobile phone signal jammer be deployed to ensure optimal signal disruption?The efficacy of mobile phone signal jammers utilized in specific locations can be influenced by various factors such as the surrounding environment, installation position, distance, and the quantity of jammers employed.

Insufficient attention was given to data analysis, plane survey, shielding coverage plan, and other essential tasks during the early stage. Consequently, blind installation resulted in no impact and poor shielding effect. To avoid such issues, it is highly recommended to contact professional shielding customer service before installing the shielding device. They can offer expert advice and guidance. Furthermore, it is advisable to seek professional installation advice before purchasing a shield suitable for 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 specified requirements for installation height are not met, and the installation position is deemed improper due to the presence of obstructions. Additionally, the use of partition walls leads to signal blockage.

3. The effectiveness of wifi jammer installed in specific locations may be compromised due to environmental factors. In particular, the presence of intelligent base stations within a distance of 200-500 meters can result in shielding failure. It is worth noting that these base stations typically operate at power levels exceeding 200 watts.When the base station encounters interference, it will automatically increase the transmission power, switch to a channel with a weaker interference signal, and have the ability to freely switch between channels. Mobile phone signal amplifiers are often found on the ceiling of locations where customers install mobile phone signal jammers.When the jammer and amplifier are employed concurrently, the effectiveness of the jammer's signal cancellation is compromised.

4. The incorrect selection of jammers can lead to their ineffectiveness. It is recommended to choose jammers based on the specific locations they will be used in. For example, prisons and detention centers should consider the completeness of channel shielding and the ability to operate continuously throughout the year. Medium-power mobile phone signal jammers are employed in prison buildings.Supplementary shielding and high-power directional shielding are achieved through the use of jammers in playgrounds and the release square, respectively, to ensure complete blocking of the prison signal. However, when prisons extensively rely on mobile phone signal jammers, it becomes arduous to manage and maintain them, resulting in escalated costs. To address this, the adoption of remote control software is being considered for efficient batch management.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.

Educators were quick to observe a shift in students' cellphone behavior when they returned to school amidst the pandemic. Their increased attachment to these devices during class became more apparent, with a rise in activities like posting on social media, searching YouTube, and texting friends.

So this year, schools in Ohio, Colorado, Maryland, Connecticut, Pennsylvania, Virginia, California and others banned the devices in class to curb student obsession, learning disruption, disciplinary incidents and mental health worries.

In no uncertain terms, Superintendent Elizabeth Lolli of Dayton Public Schools declared, "We clearly communicated our position: this behavior must cease. The academic challenges we face will persist if our students continue to be preoccupied with their phones."

Cell Phone Signal Jammer For Schools

Educational institutions may resort to the use of cell phone signal jammers to dissuade students from utilizing their mobile devices during classroom sessions. The presence of cell phones in classrooms can be highly disruptive, posing a significant challenge to students' ability to concentrate and adversely affecting their learning outcomes.

Instead of using cell phone signal blocking device, many schools have implemented policies that restrict or prohibit the use of cell phones during class time. Some schools require students to keep their cell phones turned off and stored in their backpacks during class, while others provide cell phone storage lockers or charging stations.

Furthermore, there are schools that have adopted technological measures to restrict or regulate the use of cell phones in particular zones of the school. For instance, some schools utilize Wi-Fi networks that can effectively block access to social media and other distracting websites.

In general, while the use of cell phone jamming
may appear to be an efficient means of curbing cell phone use in schools, it is important to address this issue in a lawful and responsible manner. Educational institutions should consider adopting policies and technologies that can limit or regulate cell phone use, without resorting to illegal and potentially dangerous methods like cell phone signal jammers.

The Bad

Students tend to be highly susceptible to the kinds of distractions smartphones provide. My colleague caught a student watching Grey's Anatomy during her class. Other students tweet, text, and listen to music when they should be on task. According to Jeffrey Kuznekoff, who conducted a study on phone use by college students, "You're putting yourself at a disadvantage when you are actively engaged with your mobile device in class and not engaged in what's going on." Saraswathi Bellur, a researcher at the University of Connecticut, found that multitasking in class "is likely to harm academic performance."

The post-covid-19 years have brought about heightened challenges, particularly in the academic domain, with numerous districts lagging behind by a year or more. These districts are putting forth all their efforts to support students in catching up. Surprisingly, social media platforms accessed through students' mobile phones are now being seen as a significant factor in the deterioration of mental health. Consequently, several school systems have resorted to legal measures against these platforms.

The matter has resulted in differing opinions among parents, as many critics assert that it is crucial for their children to have mobile phones as a precautionary measure for emergencies.

“We’re not trying to infringe on anybody’s freedom, but we need to have full attention in the classroom,” said Nancy J. Hines, superintendent in the Penn Hills School District, in the suburbs of Pittsburgh.

Following the return to in-person instruction amid the pandemic, Hines encountered an escalation in cellphone-related challenges within their diverse 3,000-student system. Aiming to redirect the students' attention towards educational pursuits rather than constant scrolling, the district implemented a ban in its middle school. Homeroom teachers were responsible for collecting the students' cellphones every morning and securely storing them in zippered cases. The students were then able to retrieve their phones prior to heading home.

The use of signal jammers in schools is typically against the law. Furthermore, it is questionable how the school managed to acquire them initially. Unless the school is located within a correctional facility, the procurement of signal jammers should not have been possible. It is crucial to acknowledge that signal cellphone jammer are subject to strict regulations, and the consequences for their usage are severe if one is caught.

It is likely that your school has implemented restrictions on the wifi network, allowing only school devices to connect. Within our district, we have set up several wifi networks. The Mobile Data Network is dedicated to chromebooks used on campus, while the Staff Network is exclusively accessible to staff members. Additionally, we have the BYOD network for guests, which can be disabled at any time by the school administration. It is worth mentioning that network usage significantly rises during lunch breaks and passing periods.

I believe that in most states it is illegal to operate a radio transmitter without a licence, except for low-power type-approved (in your country) devices within certain frequency bands - e.g. garage door openers, baby monitors, CB radio in some countries, WiFi etc. Cellular radio bills include a yearly licence fee - at least mine used to. It is unlikely that you would get approval to operate a device designed to cause interference; the licence for other devices often includes a clause stating that you will not cause interference. So if you use a GPS jammers you are probably guilty, at least, of an offence of operating a non-approved transmitter without a licence, if not other offences.

The operation of a transmitter inherently exposes your whereabouts to individuals equipped with a receiver, unless you possess a low-power device near a GPS receiver that remains undetectable from more than a few meters away.

Not long ago, a Special Forces soldier was accused of unlawfully killing an Afghan civilian. The soldier in question had witnessed the civilian in possession of a cell phone and, taking into consideration the circumstances and environment, along with other indicators that only experienced soldiers and police officers can identify, determined that the civilian was likely using the cell phone to activate an Improvised Explosive Device (IED). This method of detonating IEDs is frequently employed. Although the soldier was acquitted during the formal hearings and trials, the unit could have prevented a significant amount of time and trouble by utilizing a jammer.

Various styles and strengths exist when it comes to jammers. However, they all possess a key characteristic. These devices are specifically designed to interfere with a particular radio frequency. Essentially, a high-quality jammer can impede electronic communications from one or multiple points, thereby denying cell phone usage, drone activities, and a wide range of other radio frequency devices.

Undoubtedly, the employment of jammers in overseas, military, and contracting operations is significantly less limiting and represents the most effective approach to counter IED attacks initiated through radio frequency. A proficient jammer will effectively hinder remote IED detonation, thus denying adversaries the anonymity they often depend on for their protection. Furthermore, jammers will equally prove highly effective in preventing drone attacks or impeding image and intelligence gathering.

In a united effort, Oklahoma's new attorney general and other top prosecutors nationwide are urging Congress to pass legislation that would grant legal permission to disrupt cellphone signals within state prisons.

According to Attorney General Gentner Drummond, criminal enterprises can operate within prison walls. He emphasized the critical importance of providing law enforcement with the necessary tools to tackle this problem, urging Congress to take swift action.

Drummond joined 21 other attorneys general last week in a letter urging Congress to pass ''meaningful" legislation allowing states to jam cellphones at prisons.

According to the prosecutors, during their discussion with congressional leaders on Wednesday, it was revealed that inmates are utilizing contraband cell phones to coordinate acts of murder, riots, drug deals, fraud, and various other illegal activities. The concerning fact is that these cell phones are still being used without any means to block them, thus posing an active and continuous threat to public safety.

Cellphones used to direct drug rings from inside prisons, DOJ says

As the U.S. Department of Justice unveiled its latest statistics, the urgency to bring about a change in the law has intensified, emphasizing the seriousness of the situation in Oklahoma.

According to a news release issued on Friday, the U.S. attorney from Oklahoma City stated that state inmates associated with four different criminal organizations were able to acquire illicit cell phones while incarcerated. This enabled them to maintain control over their drug trafficking and violent networks by coordinating with their contacts outside the prison walls.

“Now, 275 dangerous criminals have been held accountable, more than a half-ton of poisonous drugs and 393 firearms have been removed from the streets, and $1.3 million in cash has been taken away from drug traffickers," U.S. Attorney Bob Troester said about the results of the drug prosecutions.

The news release discloses that thirty offenders were taken into custody for their participation in drug rings. Remarkably, these individuals were found to be orchestrating the operations, which were often marked by violence, through the use of smuggled cellphones.

Sentenced in December was Eduardo Rosales, a leader of a ring operated by the Southside Locos gang that distributed methamphetamine from Mexico across the state in 2019. Rosales, 37, of Oklahoma City, was already in state prison at the time for drug offenses.

December marked the sentencing of Chance Alan "Wolfhead" Wilson, who was convicted for the murder of his sister. While serving his sentence in state prison, Wilson was discovered to be operating a drug ring. Federal prosecutors have identified Wilson, a 38-year-old individual from Purcell, as a leader within the Universal Aryan Brotherhood, a prison gang.

Both individuals were given a 30-year federal prison term as part of their sentence.

Thousands of cellphones seized from Oklahoma facilities

The Oklahoma Department of Corrections revealed on Friday that a significant number of 5,247 cellphones were seized within state-run and privately managed correctional facilities during the course of last year.

"Despite the presence of cellphone-detecting K-9 units and nonstop intelligence-gathering efforts, some phones still manage to get through. That is a reality faced at all levels, from county jails to federal prisons," said Josh Ward, chief of communications.

According to court records, it has been discovered that guards have been smuggling cellphones into Oklahoma prisons. Furthermore, these devices have been illicitly transported by either being thrown over prison fences or dropped via drones.

Oklahoma officials have demanded alternative measures to combat contraband cellphones.

In 2019, Governor Kevin Stitt emphasized the significance of finding a technology-based resolution to tackle the issue at hand. This statement came after a series of gang-related fights took place in six prisons, resulting in the imposition of lockdowns.

Communication via contraband cellphones among inmates, as stated by the governor's office, played a crucial role in enabling the "premeditated acts of violence".

In the aforementioned year, U.S. Senator James Lankford expressed his support for states to employ jamming signal technology.

“Why don't we change that law?” Lankford asked on the Senate floor. “Great question. A question that should have been answered by this body a long time ago, but communications companies and cellphone company lobbyists overwhelmed this body and pushed back and say, ‘Let's study the issue.’”

He said he repeatedly met with leaders at the Federal Communications Commission in an effort to resolve the issue. "Each year ... they say, 'We're studying it.'"

FCC opposes cellphone jamming, citing safety concerns

Over an extended period, the FCC has consistently been against the inclusion of jamming wifi technology within state prisons.

The FCC has stated that it results in more problems than it solves. Furthermore, it has the ability to interfere with mobile 911 calls and public safety communication.

Lankford joined as a cosponsor for the Cellphone Jamming Reform Act in August, but despite his efforts, the bill never made it to a vote and eventually expired.

Last week, Lankford tweeted about the urgency of states acquiring the authority to jam signals.

The FCC introduced a mechanism in 2021 that permits designated prison officials to request wireless providers to deactivate cell signals, one by one, without the involvement of a court order.

The FCC has reported that the store owner proposed selling the signal jammers to the agent. Despite this, the agent politely declined the offer and proceeded to issue a Notice of Unlicensed Radio Operation, clearly stating the illegal nature of signal jammer operation.

Despite their illegality, a Dallas store owner took the unconventional route of utilizing cellular signal jammers. The underlying purpose behind this decision was to discourage her employees from wasting valuable time on their phones.

The recent FCC report underscores the intricate landscape of deliberate cellular interference, revealing the widespread use of commonly accessible cellphone jammers.

The FCC's report reveals that a complaint was filed by an AT&T employee with the commission, raising concerns about the potential use of a phone jammer near Ravi's Import Warehouse in Dallas. The website of this vast store emphasizes its wide array of affordable goods.

The complaint prompted the FCC, the US government agency responsible for allocating and managing the nation's airwaves, to launch an investigation.

As per the Federal Communications Commission (FCC), after reaching the company's premises, their agent had a conversation with Anita Bhatia, who claimed ownership of Ravi's. The FCC's official statement indicates that Bhatia admitted to the agent that Ravi's employed a signal jammer as a means of prohibiting its employees from using mobile phones during their work hours.

In 2019, Senator Tom Cotton, a Republican from Arkansas, pursued the passage of a bill that would have enabled state and federal penitentiaries to employ jamming devices. Unfortunately, his efforts did not succeed.

As per a recent report by ABC, the primary trade association of the US wireless industry continues to oppose the utilization of cellular signal jammers in prisons. CTIA, the association responsible, highlights the necessity for a multi-faceted and collaborative strategy to address the challenge of contraband phones. CTIA recognizes the seriousness of the issue and actively advocates for the implementation of solutions such as Managed Access Systems, which intercept calls originating from unauthorized phones while safeguarding lawful communications. The industry has made substantial commitments in terms of resources and funding to assist corrections officials in combating this problem and maintains ongoing cooperation with policymakers at all levels of government to ensure the adoption of effective solutions.

The subject of signal jammers is a matter of worldwide concern, and it should be noted that not all jammers are intended for malicious purposes. A case in point is a recent incident highlighted by ZDNet, where a father in France employed a signal jammer to restrict his children's access to social media during nighttime. However, this well-intentioned action unintentionally resulted in the disruption of internet connectivity for the entire town.

To ascertain the capability of a mobile phone signal jammer to offer complete wall-to-wall shielding, it is imperative to examine different circumstances.

Take a moment to examine the mobile phone signal shielding device itself. This device emits a radio frequency signal that is specifically targeted at mobile phone signals. As this signal encounters obstacles in its transmission path, it undergoes attenuation. The degree of attenuation varies depending on the nature of the obstacles it encounters. For example, when faced with an entire steel-concrete wall or a brick-concrete wall, as well as a reinforced concrete wall followed by two consecutive brick-concrete walls, the signal is capable of effectively blocking small and medium-power mobile phone signals. The radio frequency signal emitted by the device is attenuated, thereby preventing the shielded mobile phone signal from penetrating through the wall. It is important to note that the shielded mobile phone signal, being a wireless signal, lacks the ability to pass through obstacles and reflect.

Mobile phone signals can be blocked to different extents depending on the type of wall material used. For instance, walls made of light steel keel gypsum board or glass, as well as wooden doors, offer lower levels of attenuation. Additionally, even when the mobile phone signal is blocked, it can still affect the space behind the wall through open doors and windows or by reflecting and refracting off the wall, creating a false perception of the signal-blocking device having the ability to penetrate.

A signal jammer with a protective metal casing.

Does the utilization of a metal casing enhance the performance of this signal jammer?

Initially, let's delve into the advantages offered by this specific signal jammer.

With its simple yet effective structure, the aluminum profile excels in dissipating heat. Widely recognized as the preferred material for heat dissipation, it boasts remarkable performance in this aspect. Additionally, the heat dissipation teeth of the profile can be customized into diverse shapes, enabling seamless integration as the protective shell of a signal jammers. This not only adds to the product's visual appeal but also highlights the meticulous craftsmanship involved.

The affordability of aluminum profiles stems from their high production volume and extensive usability. This, in turn, significantly diminishes the material expenses involved in manufacturing signal jammers. Moreover, it eliminates the necessity for a dedicated housing, thereby reducing costs even further.

Next, we shall discuss the negative aspects of signal jammers that come with metal casings.

The product's unappealing appearance stems from its metal casing and the direct screwing of external antennas onto its body. To ensure comprehensive signal blocking for 2G, 3G, 4G, 5G, and WIFI, a mobile phone jammer requires a minimum of 10-12 frequency bands, which translates to the need for 10-12 antennas. Consequently, the device takes on the resemblance of a hedgehog, devoid of any aesthetic charm.

The metal casing, functioning as a radiator, is designed to dissipate a substantial amount of heat generated by the signal shield during extended operation. Consequently, the temperature of the casing rises rapidly, and at times, the surface temperature can even reach 60-70 degrees. It is crucial to refrain from direct contact with your hands to prevent the possibility of burns.

Using a mobile phone signal jammer through walls is not recommended, whether it is a high-power or small-to-medium-power device. The main reason behind this is the lack of guaranteed shielding effect. Therefore, it is advisable to install the mobile phone signal blocking device in a location where the need to block mobile phone signals arises, rather than relying on its usage through walls.

The significance of mobile phones in people's lives cannot be overstated. Nevertheless, their usage during conference room sessions frequently gives rise to significant problems, such as hindering the meeting's progress and diverting the attention of others. Therefore, the utilization of a mobile phone signal jammer emerges as a highly effective solution to ensure a seamless and productive meeting environment.

To prevent any interference caused by cell phones during meetings, the utilization of cell phone signal jammers in the conference room has proven to be highly efficient. By disabling the functionality of mobile phones, participants are able to fully concentrate on the meeting's proceedings without any distractions. Furthermore, this measure also plays a crucial role in protecting the personal privacy of attendees and preventing any unauthorized acquisition of confidential meeting information.

Additionally, the mobile phone signal jammers boasts an efficient signal shielding effect and wide coverage. It is capable of encompassing the entire conference room, thereby ensuring that the meeting remains undisturbed by external influences. Moreover, thanks to its advanced technology, the signal shielding effect is also exceptional, guaranteeing that mobile phones do not disrupt the proceedings.

Furthermore, cell phone signal jammers are designed with utmost simplicity in mind. Their operation is straightforward and easily comprehensible, requiring no technical expertise. Once installed in the conference room, the device is immediately ready for use. Consequently, there is no need for specialized technicians to handle its operation.

Within conference rooms, mobile phone signal jammers are designed to function within a specific range.

It is important to note that the mobile phone jammer, despite its name, does not obstruct the signal like a conventional jammer. Rather, it behaves in a manner similar to a signal jammer.

The connection between mobile phones relies on the signal tower, which acts as the conduit for transmission, following the path of mobile phone-signal tower-mobile phone. However, when a signal gsm jammer interferes with this connection path, the transmission is disrupted, causing an interruption in normal usage. It is worth noting that the signal tower itself remains unaffected by this interference. Due to the shared nature of mobile phones within a specific area, it is not uncommon to experience situations where mobile phone signals cannot be used normally, even when not in a conference room.

While conference room cell phone signal jammers have their benefits, they should not be seen as a cure-all solution.

At present, cell phone signal jammers available in the market can restrict cell phone signals from a distance of 1640ft 5in meters from the transmitting station and a radius greater than 65ft 7in. The range of the shielding can be modified. It only blocks mobile phone signals and does not affect other electronic devices. Therefore, if you are facing poor mobile phone signal even when you are not near the examination room, do not blame the signal jammer. It could also be an issue with your own mobile phone.

The frequency bands affected by mobile phone signal jammers in conference rooms are regulated by specific guidelines.

From a few Hz to several hundred GHz, the entire frequency band of electromagnetic waves is extensive. Although every segment can be utilized, some are more commonly used than others.

1. The GSM receiving frequency band is 885~960MHz;

2. The receiving frequency band of CDMA is 869-894MHz;

3. The receiving frequency band of DCS is 1805-1880MHz.

The defendant, Trenton Lisak, from Mobile, has pleaded not guilty to charges of obstructing public safety communication and drug possession on June 15, 2023.

According to the allegations made by prosecutors, he employed expensive and extremely advanced equipment from an apartment situated at the Tower on Ryan Park. Mobile County 911 officials assert that this action essentially halted communications in downtown Mobile on June 6 and caused disruptions for the following week.

The judge has set Lisak's preliminary hearing to take place on July 19th.

ORIGINAL STORY:

Expensive and advanced black market jamming device caused disruptions in police and emergency services transmissions for a considerable amount of time last week, as per law enforcement authorities.

On Saturday, Trenton Edward Lisak was taken into custody by law enforcement for impeding public safety communication, a serious offense that falls under Class C felony and can result in imprisonment for up to ten years. Furthermore, he is facing a drug charge. Prosecutors have revealed that the FBI is also looking into the case.

On Monday, Mobile County District Attorney Keith Blackwood remarked that the charge in question is out of the ordinary. He stressed the gravity of the situation, emphasizing the crucial need for law enforcement and first responders to have seamless communication abilities, regardless of their location, not just limited to downtown areas.

How out of the ordinary!

According to Blackwood, this was an entirely new experience for him. He couldn't remember encountering a similar situation before, especially not to this degree. The substantial quantity of equipment involved made it an exceptionally remarkable occurrence.

Lisak's arrest record discloses multiple charges, such as theft, breaking into cars, possession of a forged instrument, and engaging in 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.

Moreover, the judge established a curfew spanning from 8 p.m. until 8 a.m. and mandated that Lisak, who is 31 years old, refrain from approaching the Tower at Ryan Park situated in downtown. This particular apartment complex is where authorities uncovered the equipment responsible for interfering with the communication networks of all 57 law enforcement, fire, and emergency medical agencies associated with the Mobile County Communications District.

Lisak's booking information indicates that the aforementioned address is his place of residence. Nevertheless, the prosecutor informed the judge that investigators have reservations about whether he was truly residing there.

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."

FOX10 News was informed by Charlie McNichol, the director of the 911 system, that the interference caused a complete halt in communications for a full day last week.

Last week, on Tuesday, it brought about notable complications in the downtown region," he remarked. "Specifically, our tower site located at Government Plaza was the origin of the alarm signals. As a result, the first responders encountered significant challenges in their communication endeavors."

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 gps 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.”

Nowadays, almost every examination room will install an examination room signal jammer. However, this machine will become hot after being used for a period of time. The heat may affect the normal use of the machine. However, this is not certain. It's just that the heat dissipation capabilities vary depending on the brand. So, how does the signal jammer in the examination room dissipate heat? The old-fashioned signal jammer in the examination room could only rely on natural temperature to slowly cool down. But now, most examination room signal jammers are equipped with fans. Not only are these fans silent, but they also dissipate heat very well. It can help the instrument lower the temperature in time.

In addition, now schools are generally equipped with air conditioners. When the weather is too hot, the school will turn on the air conditioner or fan to ensure the safety of candidates. At this time, the temperature of the gsm signal jammer in the examination room will also drop. In fact, this thing is just like a mobile phone. In the summer, it will get hot as long as it is turned on. But it won't damage the machine. Especially for machines with better quality, you don’t have to worry.

In real life, mobile phones have become an indispensable device in people's lives. However, using mobile phones in conference rooms often leads to serious problems, such as interfering with the progress of the meeting and affecting the attention of others. Therefore, using a mobile phone signal jammer is an effective solution to ensure that the meeting goes smoothly.

What should you pay attention to when using mobile phone signal jammer in a conference room?

Cell phone signal jammers can effectively block cell phone signals in the conference room to prevent cell phones from interfering with meetings. During the meeting, participants will not be able to use their mobile phones so that they can fully focus on the meeting. At the same time, this also helps protect the personal privacy of participants and prevent others from improperly obtaining meeting information.

Although the mobile phone signal jammer is called a jammer, it does not actually block the signal. Instead, it acts like a signal cellphone jammer.

Generally speaking, the connection between mobile phones will go through the signal tower, that is, the path of mobile phone-signal tower-mobile phone. The signal jammer will interfere with the connection path between the mobile phone and the signal tower, resulting in normal transmission. However, The signal tower is used by mobile phones within a certain range, so there are often situations where the mobile phone signal cannot be used normally even if you are not in the conference room.

Conference room cell phone signal jammers are not a panacea

Mobile phone signal jammers currently on the market can limit mobile phone signals that are 500M meters away from the transmitting station and have a radius of >20 meters. The shielding radius is adjustable. It only blocks mobile phone signals and does not affect other electronic devices. So if your mobile phone signal is not good recently when you are not near the examination room, don’t blame the signal jammers. It may also be a problem with your own mobile phone.
