METHOD FOR BLOCKING CELLULAR COMMUNICATIONS Russian patent published in 2021 - IPC H04K3/00 H04W48/04 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, engaged in the creation of artificial interference in radio communications. The claimed method for blocking cellular communication includes amplification of the received broadband signal emitted by the subscriber unit, its re-emission with the introduction of a phase change according to the law of a low-frequency pseudo-random sequence in real time while maintaining the spectrum within the allowed frequencies of the subscriber unit. The phase change in the re-emitted signal is performed at a random value, which is selected from a set of sequence values ranging from 0 to (n-1)*2π/n and spaced from each other with a step of 2 π/n, and a low-frequency pseudo-random sequence determining the value phase shift, takes n integer values in the range from 0 to n-1.

EFFECT: increasing the size of the blocking zone and improving the reliability of the blocking.
