Power Line Communications (PLC) carrying information over existing power lines is arousing strong interest and producing tangible outcomes recently.
Intermingling with digital technology, PLC is overcoming handicaps such as low transmission speed and reliability and expanding into broadband communications.
Korea Electrotechnology Research Institute (KERI) recently developed PLC-based healthcare system allowing users to access real time health care information and professional advices without worrying about communication fees. PLC is also being applied to related areas such as integrated meter-reading and energy-management system on a test basis.
Meanwhile, KERI and Korea Electric Power Corporation will host IEEE ISPLC 2008 (International Symposium on Power-Line Communications and Its Applications) for three days from April 2 in Jeju Island. On this occasion, KERI and KEPCO will introduce research outcomes and demonstrate Korea’s PLC technology using the test bed in Jeju. KERI says “The test bed in Jeju is a pilot networking complex using real networking facility and provides a complete model for commercial PLC network.”
The demonstration in Jeju will present wireless Internet services using high-voltage (22.9kV), high-speed PLC network, automation system for electric power supply and remote metering based on high-speed PLC.
PLC fulfills power supply and data transmission at one time over a single power line. It is used for home network controlling home appliances such as TV, refrigerators, air conditioners and micro-wave ovens as well as PC.
