About Racom

Radio modem data networks are the main focus of RACOM since its birth in 1992. RACOM is currently one of the world leaders on radio modem market. Typical use of RACOM radio modems is in radio data networks for SCADA & radio telemetry system. Radio modems of RACOM family are suitable also for fleet management applications. RACOM modem radio is frequently used also in transaction and lottery radio networks.

RACOM radio modems exceed in unique anti collision packet protocol on radio channel. This radio packet protocol allows both polling and spontaneous communication at the same time. The possibility of store and forward repeaters enables to built large radio data networks with unlimited number of radio modems. The intelligence of RACOM radio modems is so high, that it is better to call RACOM radio modem a radio router.

Together with radio modem family RACOM designs and produces GPRS/EDGE/UMTS modems for industry applications. GPRS/EDGE/UMTS modem and radio modem can be combined in unique communication system called MORSE. Therefore MORSE joins together advantages of both radio network and GPRS/EDGE/UMTS network.

Another accessories such as communication routers, power supplies etc. are designed and produced by RACOM as well. RANEC is a network management software made by RACOM to be used for MORSE data network maintenance. MORSE is a convenient system for wireless data packet networks of any scale mainly used for SCADA and Telemetry communication.
