Wi-SUN communication to enhance power meter functionality
The Wi-SUN Alliance provides sub-GHz communication standards for meter AMR applications, as well as smart home appliance applications, due to its low power consumption and smart network connection.
Our Renesas solution uses a combination of the RL78/G1H MCU with a sub-GHz radio, an RX651 MCU, and RF products such as the F1420 PA and the F2914 switch. The ISL85413 buck converter ensures a stable voltage supply for applications where RF transmission, multiple peer accessing, and networking communication are required.
The 16-bit RL78/G1H acts as an RF transceiver to transmit and receive the data from the antenna. The signal is then amplified by an LNA or a PA. The entire process is fully compliant with the Wi-SUN Alliance-based PAN/FAN profile (IEEE802.15.4g/4e).
Key features:
- Full solution level support for the Wi-SUN standard
- Provide hardware package design support
- High output power and receive performance
