Jammer using UMTS 2100MHz covering a range of 60/70meters
Abstract
Cell phones are everywhere these days. It’s great to be able to call anyone at anytime. Unfortunately, restaurants, public places, class room, shopping malls and churches all suffer from the spread of cell phones because not all cell-phone users know when to stop talking while most of us just grumble and move on, some people are actually going to extremes to retaliate. Mobile jammer is a device used to prevent mobile phones from receiving or transmitting signals with the base stations. In this paper, we have to jam a cell phone, all we are developing a device that broadcasts on the correct frequencies. Although different cellular systems process signals differently, all cell-phone networks use radio signals that can be interrupted. GSM, used in digital cellular and PCS-based systems, operates in the 900-MHz, 1800-MHz and WCDMA 2100 bands in Europe and Asia and in the 1900-MHz band in the United States. Jammers can broadcast on any frequency and are effective against WCDMA, GSM and DCS. This project discusses the design and development of GSM Mobile jammer and aims to present a solution for the problems of occur through the cell phone. The main concept of jamming is the releasing of same frequency which is using by mobile service provider with noise so user equipment gets destruct.
