FIELD: radio engineering.
SUBSTANCE: invention refers to radio telephone systems for servicing variety of remote user stations. Cluster of system user station is removed from base station. System applies common pool of modems with frequency agility, each of which provides digital synthesis based on " time domain by time domain". To maintain communication between number of user stations and base station, the various intermediate channel-identifying frequencies is required. Power is reduced due to control of modem dials, maintenance of non-dial switched-off (reduced power) modems, and due to dial number control when the same time domain is used. Dial delay of switched-off (reduced power) modem is eliminated due to availability of all modems to high-quality synchronisation information received by one of active modems.
EFFECT: reduction of maximum power consumption.
