　　One of the most popular things used in schools today is cell phone jammer. There are many teachers and schools who see school as an institution of learning, and devices like cell phones can distract students and interrupt their learning. We all know that students stubbornly can't make phone calls in class, but they can text their friends.

These antennas are designed not to interfere with each other. However, if you try to stop the signal from leaving the device by covering it with something like metal foil, it can also affect the device's ability to receive signal jammer from orbiting satellites.

　　In order to capture this information from as many Earth-orbiting satellites as possible, taking into account any potential interference to these satellites, four different frequencies have been allocated exclusively for civil use: L1 (1575 MHz), L2 (1227 MHz), L5 ( 1176 MHz) and L6 (1278 MHz).

　　If you have multiple devices that need to be blocked; for example, a work phone and a personal phone. You also need to know the power of each incoming signal and where they are received in order to effectively block them at the same time.

　　GPS tracking devices are used to track people's movements, especially in vehicles. It can be used for good or bad purposes. For example, in some countries, police use GPS tracking devices to monitor the cars of people involved in crimes. They can check if a car is passing a certain area at a certain time.
