The Many Uses of a Cell Phone Jammer
Cellular GSM jammers are designed to prevent the reception and transmission of cell phone signals. Teachers are particularly concerned about the impact that cell phones have on students, especially high school students. Teachers have the right to control these distractions, and a mobile phone jammer can help. In a school environment, the number of cell phone calls per student is high, and students are often disrespectful to teachers. Therefore, a mobile phone jammer is often the ideal solution to this problem.
Legal uses for cell phone jammers
Illegal use of cell phone jammers and GPS signal blockers has become a common issue. Companies may use cell phone jammers to prevent their employees from using their mobile phones to track company vehicles. A recent case involves a New Jersey man who was issued a $32,000 fine by the FCC. The FCC got involved after his global positioning system suddenly stopped functioning at his worksite. This case highlights the dangers of illegally using cell phone jammers and GPS signal blockers.
One of the main concerns for jails is unauthorized use of cell phones by inmates. Prison officials have argued that the devices can prevent inmates from communicating with the outside world and committing crimes. But while jails aren’t the only places where jammers are used, many jails are considering them to keep prisoners safer. States such as New Zealand, Sweden, and Norway have banned the use of cell phone jammers in jails, while the UK has legalized their use.
Range of mobile phone jammers
The range of mobile phone jammers depends on the power of the device and the surrounding environment. For example, a hill in the middle of a city may block the signal from a mobile phone, causing it to not work. Higher-powered jammers can block all frequencies at once, while a low-powered jammer can only jam calls within 30 feet. A powerful jammer can shut down service for more than a mile, but that’s only a few feet if it’s placed on a mountaintop.
Portable jammers are also useful because they can be tuned to the frequency of a car’s keyfob. When the car is locked, a thief could turn on the jammer before pressing the lock button on the keyfob. Then, the car wouldn’t lock and they’d take your car – or any valuables you might have in the car – without any trace of the lock.
Impact of cell phone jammers on human health
Various studies have shown that high-frequency electromagnetic fields can affect the health of humans. One study, by Velayutham and colleagues, revealed that mobile phones may affect the hearing system. According to the study, exposure to 1800 MHz GSM caused the ear canal to become warmer than usual, and DPOAE domain decreased. The study also found that cell phone radiation affected the sperm motility and increased the chances of conception.
Another study looked at the impact of mobile phone jammers on hematological factors. These factors are the concentration of hemoglobin in the RBC and the width of red blood cell distribution, which is a measure of deviation in the size of RBC inside the blood sample. These factors did not differ between the experimental and sham groups. But the researchers found that rats exposed to jammers were more likely to be depressed.
Cost of cell phone jammers
If you’ve ever wondered about the cost of cell phone jammers, you’re not alone. Many people purchase jammers in order to prevent others from ignoring them. They’re effective at blocking the signals that mobile phones emit in particular ranges and frequencies. Many people buy portable jammers for this reason, but what are the other uses for these devices? A cell phone jammer can be used in a variety of places, including prisons. A jail cell phone jammer will only work on prison-owned facilities and not interfere with commercial signals.
A number of models are available, each with different capabilities. High-end jammers can block more than one signal at once. But they’re expensive compared to the cheaper single-channel models. Cheap jammers are often only good for blocking a specific signal and are only powered by batteries, so they last for short periods of time or cover a limited area. But if you’re looking for something that will keep you and your family safe and sound, cell phone jammers may be a great choice.
