In the face of signal reception and transmission, we can understand it through formulas. Although only one dimension of the communication link can be calculated (TX->RX), two dimensions (TX->RX and Jammer Phone->RX) must be calculated for the event and then compared. The “connection” that shows a stronger signal at the input of the receiver will prevail. It can be the sender (“partner”) or the interferer.
The purpose of a scrambler is to disconnect the communication link (or network) between two (or more) “partners” when they are trying to talk or transmit some data between them. There are more situations that interfere with the communication link between the drone and its operator. We can try to disrupt the communication between the mobile phone and the base, between the two tactical radios, and between the bomb and the remote control used for activation.
To avoid this, the mobile cell phone jammer sends RF energy (CW + modulation) at the same frequency as that used by the enemy link or network. The enemy’s receptors (the “hearing” side) must be transmitted both through pain and through its “partners.” The strong should have the upper hand: If the energy of the drone is more destructive than the performance of the “partner”, the “listener” will not be able to “correctly” understand the message/data. Or, if the energy of the “partner” is greater than the performance of the observer, the “listener” will be able to correctly “understand” the message/data and the communication link between the “partners”.
Sometimes, the interference signal arriving at the receiver input may be lower than the communication signal (“partner”) and still dominate. This is because the receiver usually needs a “margin” between the two input signals in order to interpret one of them (usually the stronger signal). However, in advanced communication systems, this “headroom” is sometimes even negative (meaning that the communication signal may be much weaker than the noise signal), and the receiver will still be able to interpret the signal “partner”, resulting in a difficult task. task.
