what do you mean express briefly

i mean that i need to convert the mobile to jammer
"jammer is a device that block the mobiles by sending noise "
the idea is sending any noise signal over the band of gsm that mean sweeping all the frequencies of the cell phone after that the mobile could not identify the
network .

what i need here is to know how to controle the "vco" {vco:voltage-controlled oscillator is an RF chip that convert the low frequency to high frequency according to the voltage of the input }of mobile and force the mobile to sending the noise all the time .
i know that the microprocessor of the mobile control the "vco" but i do not need the microprocessor in other meaning i need to convert the mobile to analog device that always send noise .
i do not know if i could use the vco without the microprocessor .
i hope that i illustrate the idea

you mean you need how mobile works in rx and tx.then you have to know the process of working of its various parts containing a mobile handset,there are various scimatic but the fundamental is same so you decide what do you want,

yes you are very close to my idea .beside this i need to know the signal flowchart or the path of signals from microphone to antenna or from antenna to earphone . i hope you choose a common nokia mobile to explain this
