Product Description

- The DC2-RSF1 RF Mesh Communication Module is based on SoC (System on Chip) platform as configured for energy meters and other devices to be used in Willfar AMI Solution.

A basic block diagram of the module is shown in Figure as below:



- Willfar DC2-RSF1 conforms to Wi-SUN FAN Specification, which is open-standards based secured, interoperable communications for large scale IoT for Smart Utility and Smart City networks.


- DC2-RSF1 integrates SWMW920S Radio Module produced by Zhuhai Zhonghui Microelectronics Co., Ltd (a sub company of Willfar), whose certification identifier in Wi-SUN Alliance is WSA 0215.

- In a typical application, the module will be installed in electricity metering applications.

- The module will communicate with other network devices. This can include other meters, relays, access points, Distribution Automation devices and other host devices.

- DC2-RSF1 could be adopted to Single Phase Electric Meter
