What role do cell phone jammers play in our lives

If there is an emergency meeting going on and you want no one to attend any unwanted calls or messages during an important meeting, you can take advantage of cell phone blocking technology. The technology allows people to avoid calls and messages without turning off their mobile phones. Enabling this technology directly blocks signals from base stations, making it impossible for people to communicate with others via mobile phones.

At present, the main principle of signal shielding and cell phone jammer is to emit huge noise in the frequency band used by mobile phones, interfering with the reception and transmission of normal signals of mobile phones. The gadget is often used not only to prevent cheating on exams, but also to prevent terrorist attacks, politically and militarily. But a signal jammer is not like a grocery store. It’s not something you buy and use casually.

Once again, jammers have evolved to add bluetooth and wifi bands to the scanning range, leaving several forms of communication common in society completely covered.

While many people don’t think installing screens in schools is a solution because children can access the Internet in several other places, including their homes and open wi-fi areas throughout the city, some think it’s a good move. Teenagers do not have enough maturity to use the Internet properly. Sometimes, out of curiosity or under peer pressure, they may be exposed to things they should not be exposed to. Installing a jammer is a very good initiative, so no one should make this mistake even unintentionally.

Most people don’t understand the difference between bluetooth, wi-fi and mobile data. It seems to be wireless communication technology, but the main difference between them is frequency band. In the mobile communication technology, 2G mainly works in the band of 900-1700mhz, 3G works in the band of 1900-2100mhz, and 4G works in the band of 2300-2500mhz. Bluetooth and WiFi work in 2.4GHz.
