Renesas: PLC solution enables voice communication over power lines

Renesas Electronics announced a new voice-over-power line communication solution that enables both data communication and voice communication capabilities over existing power networks. The PLC solution reduces the amount of internal wiring required in buildings, enabling reduced implementation and maintenance costs for public address systems and security systems.

The new solution consists of Renesas’ PLC software modem, which manages the PLC communications, and the RX651 microcontroller, which controls the audio codec processing. The new solution enables system manufacturers to enhance security systems by incorporating voice capabilities to an existing installation at low cost. For a new installation that includes various sensors as well as voice communication, wiring costs can be reduced by approximately 60 percent while installation and maintenance costs can be reduced up to 40 percent.

The new voice-over-PLC solution uses priority control during audio transmission to virtually eliminate delay fluctuations in voice communication, even in cases where signal control communication and voice communication operate over the same power lines. This ensures stable audio quality at all times. In addition, it combines the audio priority control feature with Renesas’ low-bandwidth PLC technology in an optimized manner to allow the use of signal lines exceeding one kilometer in length without using repeaters. By making it possible to combine data communication and voice communication over existing power networks, the new solution significantly reduces the amount of wiring required for building management systems and contributes to lower maintenance costs.
