FIELD: electrical engineering.
SUBSTANCE: proposed method can be used in low-voltage lines of 220 V to organize communication channel in frequency band of 13 to 23 kHz included in remote burglar alarm systems for objects, such as suburban plots of land, garages, shops, and the like, where means for telephone and radio communications with internal affairs agency are not available.
EFFECT: enhanced signal transfer speed.
