Chapter Ⅰ Overview
1.1 Brief Introduction
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。
