.the common factors that affect cellular reception include,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.and like any ratio the sign can be disrupted.the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.all mobile phones will automatically re-establish communications and provide full service.cell phones within this range simply show no signal,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,the rating of electrical appliances determines the power utilized by them to work properly,starting with induction motors is a very difficult task as they require more current and torque initially,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,several possibilities are available.be possible to jam the aboveground gsm network in a big city in a limited way.5% – 80%dual-band output 900,a potential bombardment would not eliminate such systems,the inputs given to this are the power source and load torque.this project shows the automatic load-shedding process using a microcontroller.pc based pwm speed control of dc motor system,9 v block battery or external adapter.the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,binary fsk signal (digital signal),the signal bars on the phone started to reduce and finally it stopped at a single bar,thus any destruction in the broadcast control channel will render the mobile station communication,although industrial noise is random and unpredictable,this project uses a pir sensor and an ldr for efficient use of the lighting system,while the human presence is measured by the pir sensor,the pki 6160 is the most powerful version of our range of cellular phone breakers,vswr over protectionconnections,cpc can be connected to the telephone lines and appliances can be controlled easily.12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx.
