SInBOn WSM-A0x Wi SUN Module

Wi‐SUN Introduction

Wi‐SUN is a wireless communication technology designed for large‐scale outdoor industrial and utility applications. It provides a reliable, secure, and low‐power solution for connecting devices in smart grid, smart city, and other Internet of Things (IoT) deployments. Wi‐SUN is based on the IEEE 802.15.4g standard and operates in the Sub‐GHz frequency range, which offers excellent propagation characteristics and long‐ rang connectivity.

Wi‐SUN Module Scope

The VC7300‐series (Vet ExCom SoC Solution) is a highly integrated wireless MCU that perfectly fits IoT networking and sensing applications. It integrates Cortex‐M3 MCU, 512/1024 KB Flash, 128 KB SRAM, sub‐GHz radio, and other functionalities such as UART/SPI/I2C, WDT, and Timer, etc.
The VC7300‐series has varieties of power‐saving modes which can be leveraged to build ultra‐low‐ power IoT networks with powerful computing capability. The embedded sub‐GHz RF transceiver features low power consumption, long‐range and robust wireless links, being able to reject large nearby interfering RF signals.
Furthermore, our module is designed to integrate with existing IP‐based networks, leveraging IPv6 protocols for seamless connectivity with the broader Internet. This enables the integration of Wi‐ SUN networks into larger smart grid and smart city deployments, facilitating efficient data collection, management, and control.
