There Are Good And Bad Aspects Of The Jammer

When you present your Drone Jammer to potential customers, the first question is always the same: “What is the range of your signal jammer?”

To better explain the problem, we will first try to explain the basic concept of communication jamming.

The role of the Jammer is to interrupt the communication link (or network) between two (or more) “partners”, when they try to talk to each other or deliver certain data between them. Blurring the communication link between a drone and its operator is a specific case among many others; we can try to scramble the communication between a cell and the base station, between two tactical radios, between a bomb and a remote control which is used to activate it, etc.

Unfortunately, most customers are familiar with communications links and equipment, but they are much less familiar with the concept and interference equipment. Therefore, they do not understand why there is no “simple” or unique answer to this question.

The objective of this article is to explain how distance calculations and / or measurements of an interference “link” are made. Clearly, the Jammer does not establish a “link” with the victim, but we can look at the interaction between them in the same way as we look at a normal communication link between two “partners”.

In general, we can say that if a communication link has only one dimension to calculate (TX-> RX), for the interference case, two dimensions must be calculated (TX-> RX and Jammer-> RX ) and then compared. The “link” which will present a stronger signal at the input of the receiver, will prevail; it can be the transmitter (the “partner”) or the jammer.
