The Wi-SUN Alliance provides sub-GHz communication standards for automatic meter reading (AMR) applications, as well as smart home appliance applications, due to their low power consumption and smart network connection.

The Power Meter with RF Communications solution uses a combination of the Renesas 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).
