Features and Benefits

IEEE 802.11a/b/g/n compliant
M12 anti-vibration connectors
SC optical fiber connection
QoS (WMM) and VLAN for efficient network traffic
Controller-based Turbo Roaming (less than 50 ms) The Turbo Roaming recovery time indicated herein is an average of test results documented, in optimized conditions, across APs configured with interference-free 20-MHz RF channels, WPA2-PSK security, and default Turbo Roaming parameters. The clients are configured with 3-channel roaming at 100 Kbps traffic load. Other conditions may also impact roaming performance. For more information about Turbo Roaming parameter settings, refer to the product manual.
Complies with all EN 50155 mandatory test items This product is suitable for rolling stock railway applications, as defined by the EN 50155 standard. For a more detailed statement, click here: www.moxa.com/doc/specs/EN_50155_Compliance.pdf

Introduction

The AWK-3131A-RTG 2-in-1 industrial AP/client devices are designed specifically for train-to-ground communication and can perform reliably even when the trains reach a speed of 120 km/h. The AWK-3131A-RTG complies with a portion of EN 50155 specifications, covering operating temperature, power input voltage, surge, ESD, and vibration, making the AWK-3131A-RTG suitable for a variety of industrial applications. Installation is easy, with either DIN-rail mounting or distribution boxes, and the DIN-rail mounting capability, wide operating temperature range, and IP30 housing with LED indicators make the AWK-3131A-RTG a convenient yet reliable solution for any rolling stock application.

Advanced Security

64-bit and 128-bit WEP (Wired Equivalent Privacy)
Enable/disable SSID broadcasts
WPA/WPA2 (Wi-Fi Protected Access) and 802.11i support
IEEE802.1X/RADIUS support
Powerful filters for access control
