Features of IoT-PLC power line communication technology

□ Optimal network configuration through IPv6-based address support

○ The existing MAC method has a low meter reading success rate when there is an error in the power facility information by configuring the network in the data concentration unit (DCU).

○ IoT-PLC system expands communication coverage by configuring the network by finding the optimal communication path through the IPv6 based protocol in the modem.

○ In case of DCU malfunction,each modem reconfigures the network,so data transmission/reception function can be performed through another DCU.

□ Reliability and coverage expansion by applying the latest communication technology

○ Designed with modulation and demodulation technology that can make the most of the low-frequency band,which is less affected by attenuation of communication signals in underground lines (except for the prohibited band)

○ Supports diversity that distributes and transmits data signals in frequency and time to cope with signal attenuation and various noise situations.

○ By adopting a channel codec that supports optimal data correction performance,communication reliability is secured even on noisy lines (RS code → Turbo code)

□ It is possible to significantly reduce the construction and operation cost of AMI system

○ All power line communication technologies applied to IoT-PLC have been non-discriminately opened so that the AMI system can be built without the burden of patent fees.

○ IoT-PLC modem consumes about 750mW less power than HS-PLC by optimizing power consumption,reducing costs by about 3 billion won per year based on 5 million modems.

○ KS-PLC and HPGP cannot be installed in the same transformer group as they are recognized as mutual noise,but IoT-PLC can be operated together with existing PLC facilities.

IoT-PLC communication method application field

○ By supporting IPv6,it can be applied to various application fields such as IoT communication,and it is possible to build the most economical AMI supplementary service operation system along with remote meter reading and electricity usage information,which are basic functions of AMI.

○ It can significantly improve the performance of the AMI system of high-voltage power supply apartments,and can be applied to 5 million units promoted by the government by 2022 and 2.3 million units promoted by private AMI projects (total of 7.3 million units).

○ Applicable to projects with poor power line communication environment such as road construction and local government's LED street light dimming control project (about 3.5 million units)

○ As the world's only power line communication solution applied to AMI projects such as underground electric lines and long-span electric lines,securing performance and price competitiveness in overseas business
