For what purpose the uav jammer was born

Usually, in the Anti-Drone application, the intention is to jam the Drone when it is hundreds of meters away from the sensitive area/perimeter (where the Jammer is installed). For example, we want to jam a Drone, which is 300 meters away from the Jammer and flying at an altitude of 10 meters. As can be understood, in this case the diagonal distance between the Jammer and the Drone is about the same as the horizontal distance between them. Therefore, in order to simplify things, we will be discussing horizontal distances and we will not bother our selves with calculating the exact distance, because the difference is quite small.

This equation, though in its simplest form (without cable losses, SNR, etc.), can be used for the calculation of ANY 4G jammer scenario/budget. As can be seen, it consists of two dimensions/links (Jammer<->Drone and Operator<->Drone), and not only one dimension/link as in the case of a communication link. In other words, for each specific condition of the Operator<->Drone link (specificoutput power, antennas gain and heights, distance, etc.), exists a specificscenario/condition of the Jammer<->Drone link, required in order to jam It… that is why answering the question of “What is the range of your Drone Jammer?” is never an easy task. There are MANY possible answers to it !

Its basic principle

Cell phone jammer  is the App that allows you to detect presence of jamming devices around. In that situation your mobile phone loses the ability to make a phone call. If it happened, the App gives you a visual or sound message. The time for reaction on a working jammer depends on hardware communication part of your device and typically can be in 30-60 sec range.

An effective jammer does not necessarily need to be outputting a significantly higher power level than the devices it wishes to jam. most Cellfones use CDMA technology which means they are all essentially broadcasting on the same frequency, but they are all synchronized with the base station and transmit different “codes” within that frequency to allow the base station to decipher them individually. However, a single rogue phone on the CDMA frequency that is constantly blasting out garbage noise instead of carefully synched CDMA codes will drown out its immediate neighbors…
