Raspberry Pi Cell Phone Blocker Block Do Not Track

The main purpose of a cell phone blocker is to block cell phone signals in a specific area. So when you're looking for Raspberry Pi Cell Phone Blocker you should think about what type of cell phone signal you want to block. Since 3G and 4G cell phone signals are mostly adapted, the jammer should be able to block 3G and 4G cell phone signals. This device can meet this need. Also, this is an optional model, so you can choose to block all kinds of cell phone signals you want in different situations. All you have to do is press the button because this device is very easy to understand and operate. You may also want to block the GPS signal, as this signal can be used to develop trackers. When the GPS signal is blocked, no one can track you anymore. Therefore, your personal privacy is protected. What's more, this portable device protects you from being tracked while you're on the move, as it works with the battery. The car charger is designed so that you can charge your device in the car.

Our mobile phones must emit qualified electromagnetic waves in order to connect to our telecommunications carrier base stations. Different communication systems use different frequencies, so that everyone is safe and does not interfere with each other. The basic principle of cell phone jamming equipment is to emit the same radio frequency signal as the cell phone. Since the frequencies are the same, the cell phone cannot tell which signal is a regular base station signal, thus "jamming". As long as there is a machine on the same frequency as the phone, the base station will make a lot of "noise" when it tries to connect to the phone. You will find that the signal from the phone is unrecognizable, so you will refuse to communicate with the phone. In the early days, Raspberry Pi Cell Phone Blocker only blocked one set of frequencies, like 2G, while sophisticated jammers can block several types of networks simultaneously, like 2-3-4-5G. So how is this multi-network interference achieved? Actually simple. That is to say, the interference bands corresponding to these three signals are repeated in a cyclic manner, covering these three interference bands at the same time. The interval of this cycle is so small that the mobile phone has no chance to speak, and can only sit and do it quietly. a brick. Covering 2/3/4/5G, what about bluetooth and wifi? It doesn't matter, it can be done easily. cell phone jammer Evolved again, adding the frequency bands of bluetooth and wifi to the scanning range, so that several common communication methods in the society are completely covered.
