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。

1.2 Module Features
