Introduction

The AWK-3131A-RTG Series Wi-Fi 4 (802.11n) railway train-to-ground IP30-rated wireless AP/clients are designed for reliable train-to-ground (T2G) communication, supporting seamless controller-based Turbo Roaming with handover times under 50 ms. Featuring both M12 and SSC models, the AWK-3131A-RTG Series meets different deployment needs, while the DIN-rail design and QMA antenna connectors simplify installation.

  • WLAN Standards

    2.4 GHz: 802.11b/g/n with 64 QAM support, 20/40 MHz
