Cell Phone Jammer – Is it Legal to Buy on Amazon?
If you’re thinking about buying a cell phone signal jammer, you’re not alone. Amazon is just one of many retailers in the United States that sell jammers. A simple Google search turned up dozens of companies selling these devices. In addition to Amazon, retailers are also required by the FCC to state in advertising that they are illegal to sell. While Amazon is an excellent resource for locating jammers for sale, you need to know that the FCC is very strict about this issue.
Car tracker jammer
There are two basic types of jammer available in the market today. One type operates on the GNSS or GPS frequencies, while the other blocks the signals from the GSM networks. Using a GPS jammer will effectively make your vehicle invisible to tracking systems. This type of jammer is not widely used by motorists, but is frequently used by truck drivers and taxi drivers. This type of jammer can cause damage to GPS equipment when activated and must be used in conjunction with a signal blocker.
The first type is the most commonly used. It blocks GPS satellite navigation signals and other kinds of cellular phone signals. These devices are also used by teachers to prevent their students from being spied on by their peers. The other type is the Personal Anti Drone Jammer, which can frustrate spying drones. The last type of jammer is useful for preventing noisy neighbors. If you’re looking to block cellular or WiFi signals, a jammer made of 555 timers is the best choice. However, if you’re not willing to go through this hassle, a cell phone wrapped in aluminum foil might be a great choice.
Portable 8-band cell phone jammer
Portable 8-band cell phone jammer is a convenient device that blocks signals from all four cell networks. It is a perfect tool for any home or office, and it can work in various locations, including classrooms. With its powerful 4W output and 8 powerful antennas, it effectively blocks all signals within its specified range. It also has a selectable jamming mode, which means you can choose which band the jammer will target. The compact size also allows you to choose which frequency to jam, which means it won’t affect other bands. This device also does not interfere with the signal from the uplink station.
Besides office buildings, portable cell phone jammers are great for protecting children in school. They can be hidden in a cabinet or teacher’s desk drawer. Hence, children can’t be distracted by their mobile phones while in class. They can also prevent the use of cell phones in prisons. As cell phone usage and illegal smuggling have grown exponentially in the last few decades, portable 8-band cell phone jammers are highly useful in these settings.
Type “B” device
Cell Phone jammers of the Type “B” variety do not send an interfering signal on cellular control channels but act as detectors in designated quiet areas. Because of their unique identification numbers, they can communicate with the cellular base station. Once they detect the presence of a mobile phone, they block the establishment of the call. Thus, they are a useful tool for blocking unauthorized cell phone use in a public area.
Cell phone jammers are typically made of three components. The transmitter section is a power amplifier, and the receiver is the jamming signal. The Type “B” device can be used to disrupt the communications of multiple mobile phones. Its power output can vary, so it is important to choose a unit that matches the receiving station’s power output. Both types of devices have similar functions, but they differ in frequency selectivity. A jammer designed to disrupt one mobile phone frequency will interfere with more than one mobile phone signal.
Legality of cell phone signal jammer
Although cell phone signal jammers may be tempting to buy, they’re completely illegal in the United States. Doing so can result in hefty fines, the seizure of your illegally obtained equipment, and even criminal sanctions. In some cases, you may experience loss of service due to a variety of reasons. Before you buy a signal jammer, contact your wireless provider or equipment manufacturer to determine the cause. If you can’t figure out what’s causing the problem, try troubleshooting methods recommended by your service provider.
Many people are concerned about the legality of cell phone signal jammers, which are becoming increasingly popular in restaurants and theaters. In some cases, blocking cell signals may even be justified for a greater good – like safety for drivers. In one case, a Texas warehouse owner was stopped from selling his signal jammer after AT&T complained. The owner admitted using the device for safety reasons, and was asked to give up the device, but eventually sold it to an FCC agent who contacted the company.
