METHOD FOR CREATING NON-MODULATED ACTIVE INTERFERENCE FOR SUPPRESSING MOBILE COMMUNICATIONS INSIDE A BUILDING Russian patent published in 2007 - IPC H04K3/00 

Abstract RU 2292651 C1

FIELD: technology for radio-electronic suppression of radio-electronic means, possible use for aimed interference with mobile communications within a building.

SUBSTANCE: method includes receiving radio electronic means signals and emitting interference signals from two points in space, beginning phases of which have no determined connection, while frequency of first interference signal f1 and frequency of second interference signal f2 is selected from condition f1=f2=fp, where fp - working frequency of radio-electronic device being suppressed.

EFFECT: decreased radiation power of signal of interference required for full suppression of mobile communications within given area of space.
