3-1-1 Inazu-cho, Toyonaka City, Osaka 561-0854 Japan
Tel: +81-6-6866-8529, Fax: +81-6-6862-3004

This Power Line Carrier communication system is approved as a national standard PLC communication method by Echonet Consortium, a standardization organization enhancing network home-appliance development. The key technology is Mesa-SS method that has great advantages in anti-noise and high signal margin characteristics.
Now this technology is under field-testing process at 300 households in Kansai region from 4/01/02.
Its outstanding anti-noise performance can be seen at our booth. Please visit!!

Instant Broadband Solution (PLC)

  Company: Sumitomo Electric Industries, Ltd.
  Responsible: Kenichi Hirotsu
      Energy Apparatus & Systems R&D Dept.
1-1-3 Shimaya, Konohana-ku, Osaka 554-0024 Japan
Tel: +81-6-6466-5631, Fax: +81-6-6466-6583

As an instant broadband solution, PLC modems will be displayed. Applications to Medium Voltage (MV) and Low Voltage (LV) Line are explained, and the outline of the trial service in ENDESA will be described.

High Attenuation EMI Technology for PLC-Blocking Filter

  Company: TDK Corporation
  Responsible: Mitsunari Suzuki
      Technology Group, Corporate Research & Development Center
2-15-7 Higashi-Ohwada, Ichikawa-shi, Chiba 272-8558 Japan
Tel: +81-47-378-9245 (ext.7303), Fax: +81-47-378-9178

We exhibit newly developed high attenuation PLC-Blocking Filter technology.
The one of PLC issue as EMI problem is how to prevent the leakage of communication data to the outside of communicating area. For this purpose, filtering performance is necessary to exceed the dynamic range of PLC signals.
We have developed high attention blocking filter based on our new EMI technology, and confirmed the solution to block PLC-signals in the range of 2M - 30MHz.
In the case of locating it at the house connection, it will block the communication between indoor and outdoor.

Dispersed Tone Power Line Communication Modem

  Company: Mitsubishi Electric Corporation
  Responsible: Hitoshi Kubota
      Information Technology R&D Center
Processor Architecture Technology Dept.
System LSI Team Manager
5-1-1 Ofuna, Kamakura-city, Kanagawa 247-8501 Japan
Tel: +81-0467-41-2087, Fax: +81-0467-41-2639


Dispersed tone technology for power line communication modems is introduced. With this technology, cost-effective and reliable power line communication systems can be achieved. Expected applications are home energy management systems, home security systems and so forth.


Using IT800 PLCs as Microsoft Simple Control Protocol (SCP)Network devices, we will demonstrate SCP and bridged SCP to UPnP system.
