Product Descriptions

The E51-470NW16S is the ideal SoC (System on chip) hardware module for long distance, low power transmission, and it is equipped with Silicon Labs' EFR32FG25 series chip, which can achieve wireless broadcasting up to 0.3 to 2.5 kilometers in dense urban canyon environments with minimal data loss. It also supports the orthogonal Frequency division multiplexing modulation (OFDM) technology introduced in Wi-SUN Field Local Area Network (FAN), which can achieve high data bandwidth of up to 3.6 Mbps. As data rates increase, the large networks required for applications such as smart cities and smart utilities can be realized, where nodes can be in the thousands.

The E51-470NW16S wireless communication module has small dimensions, rich interface resources, and supports users' secondary development, which can be widely used in the Internet of Things industry.
