New Power Line Communication (PLC) that Enables Mixing of Data and Voice Communication in Power Line Network from Renesas

Power Line Communication (PLC) is the new era for power and electronics field. Renesas Electronics announces on 11th April 2017, that it has developed “PLC (Power Line Communication) voice communication solution. So this solution enables mixing of voice communication as well as data communication in existing power line network. The company will commercialize the new prototype a software and reference boards as a solution and plan to offer it from around September 2017.

Power Line Communication New Technology

The solution combines LSI “R9A06G037” which handles the transmission and reception of PLC. Also there is the field use of “RX651” microcontroller which processes voice codec. So that it can realize stable voice communication even when it has mixing with data communication on the same power network. Here the voice transmission new technology works to suppress sound interruption (delay fluctuation) to almost zero by priority control at the same time. It is said that prototypes of software and reference board can withstand the wiring of 1 km or more length. So it is possible to communicate on long distances without using repeaters.

Cost Savings in Power Line Communication

This makes it possible to add voice-attached security systems. Also this is an option for low cost budget. And it can reduce the the number of wires when wiring of various sensor. So with the new facility the communications on the power line network can reduce the cabling cost up to 60%. Furthermore, since the wiring is only requires for the power lines. So Power Line Communication reduces the wiring management system inside the building and contribute to the cost reduction of maintenance.

Power Line Communication Date of announcement

This PLC voice communication solution was exhibited at the company’s private comprehensive exhibition “Renesas DevCon Japan 2017”.
