OAO "AGAT-SYSTEM" has designed and started batch manufacturing of “Agat-R801” locomotive terminal of GSM-R standard in the context of “Creation of modern radio communication systems and development of their manufacturing in the republic of belarus for 2007-2010” state scientific and technical program (SSTP “Radio communications”) for the benefit of the Ministry of Transport of the Republic of Belarus. The company has received permission to use radio frequencies for manufacturing of this equipment. The terminal complies with the requirements of international standards ETSI TS 151 010-1, EIRENE. SRS (v.15), FRS (v.7) in its basic parameters, when operating in GSM-R network.Supported services:
• GSM phase 2/2 + communication services;
• GSM phase 2/2 + additional services;
• GSM phase 2/2 + data transmission service (GPRS)
Power class - 2 (maximum output power - 8W).
Sensitivity - minus 104 dBm. Frequency range (MHz):
• during transmission - 876 - 880 (UIC);
• during reception - 921 - 925 (UIC).
The terminal is power supplied by the voltage ranging from 24V to 110V DC of onboard network of the locomotive with a tolerance of the supply voltage of ± 20%.
Basic package set
• Radio unit
• PUR-01 radio control panel
• MP-01 control panel manipulator
