Jammers can prevent students from being scammed

Mobile phone jammers sound like this. Devices designed to prevent the transmission of mobile phone signals or interfere with the reception of mobile phones. Their role is to generate interference within the frequency range used by the mobile phone, thereby disrupting the communication between the mobile phone user and the mobile phone signal tower. But why do people think that cell phone jammers are more common and used in public schools than in any other government agency? Even a private company? Probably because it was discovered when using a cell phone jammer to block the cell phone signal in the school.

In 2015, a school district in Pasco County, Florida passed a policy instructing students to keep cell phones and mobile devices turned off during classes. When this policy change has little or no impact on student behavior in school, the teacher decides to take action.

Science teacher Dean Liptak was tired of watching a class addicted to a smartphone, rather than taking a class, tired of ending it with a cell phone jammer. Can schools block cell phone signals?

According to a report in the Tampa Bay Times, Liptak activated the signal jammer for three days from March 31 to April 2. At first, the teacher’s strategy seemed to work. Until Verizon complained that someone at Fivay High School was mocking his network.

After determining that Liptak was the cause of his network problem, Verizon suggested that efforts to disrupt his mobile phone would damage the signal of the unit outside the school. Liptak insists that this is only to solve the problem of distracting students, not to cause problems in schools.

Liptak believes that if the intended purpose is not malicious, the use of cell phone jammers is allowed.

The school district doesn’t think so. In a letter from Kurt Browning, the head of the Legislative Yuan, Liptak was told to suspend his job for five days. He explained to the teacher: “Your behavior may not only violate federal law, but also pose a serious risk to security-critical communications, thereby preventing others from making 9-1-1 calls.

Although many websites are actively selling “cell jammers” or “signal blockers” to disrupt cellular communications and create improvised “quiet areas” in cars, schools, theaters, restaurants and restaurants, use these devices elsewhere In fact constitutes infringement. According to federal law.

In fact, not only is it illegal for consumers to use cell phone portable jammer in the United States, but retailers are also prohibited from selling it for consumption. Visiting the official website of the Federal Communications Commission (FCC), its policy is very clear:

“We remind and warn consumers that using mobile phone jammers or similar devices that deliberately interfere with, block or interfere with mobile phones, police radar and other authorized radio communications violates federal law, GPS and Wi-Fi.”

Except for some isolated incidents, such as disgusting Florida science teachers taking things into their own hands, the school does not seem to have a big conspiracy to use cell jammers to prevent students from calling or texting. class. At best, it is in the best interests of school officials to maintain cellular communications for safety and liability reasons.

If interference is not the most common cause of poor cell phone reception in the classroom, why is the school cell phone reception poor? What should you do to signal at school?

When it comes to weak cell signals, students and teachers are not alone. This year, most of the country ’s 273.8 million mobile phone users will experience poor cellular connectivity at some point.

However, schools may be more sensitive to bad or unreliable cellular signals than other buildings.

According to a report from the Green School Center, in December 2017, 2,000 schools from kindergarten to grade 12 received LEED certification. This is an important milestone, especially for the use of renewable energy on site and the use of low-carbon materials to save taxes and improve efficiency.

The bad side? In many LEED-certified school buildings, energy-efficient windows are used, and foam-insulated thermal insulation materials and metal structures are also very effective in preventing incoming signals from cells. For schools built in new communities or rural areas, the distance to the nearest cell phone tower (not to mention natural and man-made obstacles) can also affect the signal of the building.
