FIELD: transport.
SUBSTANCE: invention relates to wireless communication hardware and can be used in passenger train wireless address emergency signaling and intercom systems, and for communication with remote stations. Proposed system comprises metal case with sealed terminals and connector assemblies that houses mother board arranged pads and accommodating DECT base stations controller. Metal platform is arranged above mother board to support mother board power supply, antenna module heater power supply, device providing protection against polarity reversal, and antenna module cable fasteners. Mother board power supply and antenna module heater power supply are connected to device providing protection against polarity reversal that can be connected to car electric power supply system. Mother board comprises connector assemblies for connection to antenna modules and system phone. Additionally, proposed system comprises at least two antenna modules, each comprising two DECT stations connected to controller. Antenna modules are arranged on the roof of staff car and connected to connector assemblies of mother board.
EFFECT: higher safety.
