This paper aims at determining the remote meter-reading strategy to correspond to the ubiquitous environments. At first, it survey and analysis the present situation of domestic and foreign remote meter-reading system . Next, the advantage and the disadvantage are compared for communication methods between meter-reading device and gateway in home, which include ADSL, PLC, CATV, RF, CDMA and wireless lan etc.. Finally, the CDMA/RF based remote meter-reading system, the CATV/inter-net based remote meter-reading system, the PLC(Power Line Carrier) communication based remote meter-reading system and the optical cable/RF(PLC) based remote meter-reading system are surveyed and analyzed among domestic and overseas remote meter-reading systems. And, it is identified that the optical cable/RF(PLC) based remote meter-reading system among those is very effective at the view points of the economics and easy of installation.
Key Words : Ubiquitous System, Remote Meter-Reading System
