Japanese semiconductor manufacturer Renesas has launched two new sub-gigahertz band wireless communication solutions for smart meters and Home Energy Management System (HEMS) devices, compliant with WI-SUN standard networks.
At the core of these solutions is the RAA604S00 wireless communications System on Chip (SoC) which offers a dual-address filtering function for simplified communication control of smart meters, HEMS and other devices on a single chip.
The solution is reported to be the world’s first to be adopted as a certification device for testing Home Area Network (HAN) devices inter-connectivity under the Wi-SUN standard.
Renesas says that the solution also allows interconnectivity with third-party devices to simplify the process of certifying user goods, thereby shortening the development time and allowing stable communication.

The development follows Renesas’ work to expand its lineup of short-range wireless communication solutions with support for technologies such as Bluetooth® Low Energy (BLE).
In April, the semiconductor company announced the certification of the second generation of its OFDM powerline modem for worldwide frequency bands.
Renesas is the first supplier to achieve certifications for all frequency bands, defined by the G3-PLC Alliance, including ARIB (Japan Route B), Cenelec A and FCC.
G3-PLC is a technology able to address the challenges of powerline communications in the harsh, dynamic environments, found in metering applications.
The technology is able to help combat external disturbances and make efficient use of the available spectrum, through the use of dedicated modulation methodologies.
