Abstract

With mobile telephony reaching many people's budget, cell phones work for a wider userbase. Mobile technology is a technology type that is used primarily in cellularcommunication and other related aspects. The broad use of cell phones may cause someproblems such as irritating ringing sound or vibration that is not appreciated in some areas.One of many possibilities to disrupt these mobiles are by installing certain devices whichmake mobile phones obsolete. While different cellular systems produce different frequencyrange signals, all mobile phone networks use radio spectrum frequencies. And so, thesesignals can be blocked using different jamming techniques. This project discusses the designand implementation of a basic jammer for mobile phones. A cell phone jammer circuitry aimsat producing signals of the same frequency as the mobile signal and disrupting connectionbetween base station and mobile phone. Thus, avoiding transmission or reception of radiosignals by the mobile phone. The military first created and used the communication jammersfor spoofing and various other applications. Spoofing is the method of concealing acommunication from an anonymous source as being from a genuine known source. Since cellphone jammers interrupt contact and disrupt the operation of authentic mobile phonenetworks, in many jurisdictions the use of such devices is not accepted and is illegal. There isa risk that when operational, these jammers can also block access to various emergencyservices which is undesirable. Hence the authority must have a license to use the systemlegally and make sure it doesn’t interfere in the working of other essential organisations inany manner. Some countries have regulations that their telecommunications authoritiesfederate as to where and when a jammer for mobile phones should be used. Irresponsible useof jammer cell phone will play havoc with the coverage map of a cell phone carrier.Keywords: bandwidth, coil antenna, gain, jammer, signal
