The jammer is designed for those who want to block all kinds of signals, including cell phone signals and GPS signals. It can block cell phone signals from 0 – 4 GHz or 2.4 GHz, but it cannot block GPS signal from 1.2 GHz.
Cell phone jammer can allow you to completely shut down all mobile phones within the required range. As long as the cell phone jammer is turned on, any mobile phone (whether it is a 3G,4G or other mobile phone) within the specified range will not be able to communicate or receive a signal from the base station, so as to achieve the intended purpose of isolation and protection.
A cell phone signal jammer is a device that blocks cellular communications. It can be used to block cellular phones in a specific area, such as an office or school building. For example, you might use a cell phone jammer if your employees are frequently distracted by incoming calls and texts during working hours. Cell phone jammers are also useful for blocking signals in places like theaters and meeting rooms where important information needs to be shared without distractions from mobile devices.
Cell phone jammers are considered illegal in many countries because they prevent people from using their phones when they need them most: emergencies! However, some countries allow the use of cell phone jammers under certain circumstances (for example, with the permission of local authorities). And there are legal ways to get around this problem by using software that blocks calls on Android or iOS devices without affecting other things on your network (like Wi-Fi).
The main advantage of using this jammer is that it can isolate your own cell phones and avoid being disturbed by others. In the classroom, it can also be used to prevent students from cheating in exams.
Do you know how cell phone jammers work? This device jams the frequencies used by mobile phones. The jamming frequency depends on the type of mobile phone you are looking for.
You can use a portable cell phone jammer to prevent people from using their phones in places you do not want them to. For example, if you are in a restaurant and want people to have conversations without being interrupted by someone’s mobile phone, then you might need a cell phone jammer. If you are in an exam hall and do not want students using their phones during the exam, then you may also need one of these devices.
They work on several different types of frequency and depending on what type of device they are designed for will block different frequencies or even specific phones from working within its range.
The most common device is a portable cell phone jammer designed to block transmissions between cell phone towers and specific handsets. In addition, there are also high-power fixed installations that can disrupt signals over wider areas such as airports and bus stations. These devices interfere with Global Positioning Systems (GPS), which use satellite signals to track location information and help guide services like Google Maps and Uber find their way. but the effects will eventually wear off, especially if someone else uses GPS nearby.
The purpose of a cell phone jammer is to block signals from being transmitted by the device. The signal can be blocked in a number of ways: through the use of an antenna or other method that sends out electromagnetic energy, which will interfere with signals from cell phones and cause them not to work. Cell phone jammers can be used for law enforcement purposes as well as for personal reasons, such as preventing people from calling in sick at work or making sure kids aren’t texting during class time
