Signal jammer reduces wireless fidelity network and global system in local environment

Abstract

Cellular networks are a way of long distance communication without the use of cables, this system is a modern style of communication that was previously communication using a landline-based telephone. Cell phones (cellphones) or cell phones (cellphones) are electronic-based telecommunications devices that have the exact same basis as telephone telecommunications devices using cables or wireless wireless. The use of cellular or wireless phones is very useful, but in certain conditions their use can be limited because it can interfere with people around him such as the implementation of worship, examinations, meetings and so forth. To answer complaints about how to reduce cell phone and wireless signals, a tool that is able to deactivate GSM and Wi-fi cell phone signals at certain radii will use a jammer, a device that works by emitting full noise signals at 900 MHz frequency banks, 1800 MHz and 2700 MHz, so that the communication device cannot be used until the time limit and the distance of the radius that reaches the communication device. The results of this study have been successfully carried out by deactivating cell phone and wireless signals at a maximum distance of 7 meters from the jammer.
