Zusammenfassung: | FIELD: electro-radio engineering, possible use for delivering notification broadcast signals to clients via ultra long-wave channel. ^ SUBSTANCE: device additionally includes commutator of lines of manipulation connected to ultra long-wave transmitting radio-stations. ULW radio-stations emit electromagnetic waves, received by client radio-receivers at extensive distances (2000 kilometers and more). ^ EFFECT: increased delivery distance of broadcast signals with given time-probability characteristics along ultra long-wave radio-channel of pager notification system. ^ 1 dwg |
