[Introduction]:E51-470NW16S is a long-distance, low-power transmission SoC hardware module. The module uses SiliconLabs' EFR32FG25 series chips, which can achieve wireless broadcasting up to 0.3~2.5 kilometers with minimal data loss in dense urban canyon environments. . It also supports the introduction of orthogonal frequency division multiplexing modulation technology (OFDM) into Wi-SUN Field Area Network (FAN), which can achieve high data bandwidth of up to 3.6Mbps. It enables the large-scale networks required for applications such as smart cities and smart utilities, where there can be thousands of nodes. It has small dimensions, rich interface resources, supports secondary development by users, and can be widely used in the Internet of Things industry.
