|Powerline Communication (PLC) is newly emerging as new means for Automatic Meter Reading (AMR). According to a survey, power utility used to incorporate CDMA and RF including Zigbee for AMR application. However, industry quickly shifting weight to PLC with recently announced nationwide project such as Power IT is being recognized as next generation technology.
KEPCO KDN, subsidiary of KEPCO, recently supplied PLC modem and digital meters for low voltage AMR project site in Daejeon metropolitan city.
Jung Il Kim manager in KEPCO KDN says that "Although RF was primarily used until now, PLC will be adopted for AMR application if field trial proves successful. CMDA method used in high and medium field costs a lot of communication fee."
Nuri Telecom with expertise in Zigbee technology has initiated to develop remote inspection system based on PLC. Young Duk Kim as a member of committee in Nuri Telecom says "It seems that industry will embrace PLC technology for AMR application. We are closely cooperating with Xeline having broadband technology and Planet IT having narrowband technology."
