Company Profile
Willfar Information Technology Co., Ltd.
- Established in 2004;
- Listed on the STAR Market of the Shanghai Stock Exchange in December 2019;
- Leading supplier of meter reading (AMI) equipment and operation service;
- The first company to develop "One DCU Reading Multi-meter" solution in China;
- The first company to have large-scale application of technologies and systems like "CPU smart-card Charge and Control", "One DCU Reading Multi-meter", LoRa-based RF Communication and "District Metering Area (DMA)”

Introduction

- DC210 RF Repeater unit is a Repeater device will be a relay node in RF Mesh Neighborhood Area Network (NAN).

- The DC210 Repeaters will form a Mesh amongst themselves to reach the Gateway either directly or via hops in the Mesh, which used to extend the distance of communications.

- Willfar DC210 RF Repeater integrates the DC2-RSF1 RF NIC, which is according to Wi-SUN FAN Specification. Wi-SUN is open-standards based secure, interoperable communications for large scale IoT for Smart Utility and Smart City networks.

- DC210 RF NIC integrates Zhonghui SWMW920S Radio Module, which certification identifier in Wi-SUN Alliance is WSA 0215.

- The DC210 RF NIC contains transceivers operating in 900 MHz.

- In a typical application, the module will be installed in electricity metering applications. The module will communicate with other network devices using the 900MHz. This can include other meters, relays, access points, Distribution Automation devices and other host devices.

Antenna Terminology

Typically, the external antenna cables are routed to a bulkhead SMA connector on the outside of the host enclosure. An external antenna solution will require safety isolation from the AC mains voltage.

Situation

For smart meter required data repeating function. Pluggable.
