Introduction

The AWK-3131A-RCC Series is a range of IP30-rated Wi-Fi 4 (802.11n) AP/clients designed for railway onboard use, providing a reliable wireless solution for dedicated applications such as inter-carriage backbone networks and onboard passenger infotainment systems. The Auto Carriage Connection (ACC) feature simplifies deployment and enhances the reliability of wireless carriage backbone networks. Optimized for passenger Wi-Fi services, the AWK-3131A-RCC Series supports up to 60 client connections and data rates of up to 300 Mbps. In addition, these devices can be powered via PoE for easier installation and flexible deployment.
