Well this question is on technology.?
In a cell-phone jammer,there are components.They are voltage-controlled oscillator,tuning circuit,noise generator,RF amplifiication (gain stage),Antenna and power supply.Here’s the question:how these components help the cell-phone jammer?Any useful information about these components will be appreciated.Please explain the controls of these components as clearly as possible.
It is almost impossible to jam a cell phone. They use frequency hopping techniques and information coding that make it virtually impossible to jam. By the way, don’t try. If you’re caught you’re probably looking at a few years in jail and tens of thousands in fines.
