Design and Implementation of Cell Phone Jammer by Using Microcontroller

Abstract

Cell phones are unable to receive or send signals from mobile network base stations when a mobile jammer is installed. Without interfering with other forms of communication, mobile jammers efficiently disable cell phones inside designated, regulated zones while a mobile jammer may be used anywhere, places like temples, libraries, and hospitals are particularly good places to utilize it because phone calls can be quite disruptive there. In the mobile phone frequency band, the jamming device transmits an RF signal. As per the other radio jamming the mobile jammer blocks mobile phone use by sending out the radio waves along with the same frequencies to the use of mobile phones. This affects the interference to the communication between phones and communicating towers for renders the phones unusable. Mobile phone jammers can affect several factors the presence of buildings and landscape, proximity to the tower, indoor and outdoor settings and mainly the temperature and humidity play a particularly significant role in it. People constantly interact with this technology in the modern world, and all these people have secure data and confidential information. However, in this case, someone uses this technology and tries to get the data illegally.
