Features and Benefits 

  • Redundant 12 to 48 VDC power inputs
  • Controller-based Turbo Roaming (less than 50 ms)
  • Supported models: AWK-RTG series
  • IEEE 802.11i-compliant wireless security
  • DIN-rail or wall mounting (optional) for onsite installation
  • -40 to 75°C operating temperature range (T model)


The goal of zero-latency-roaming is to create networks that maintain communications seamlessly as clients move from one access point to another. For this, as a part of the AWK-RTG series, Moxa has introduced the WAC-1001 with Controller-based Turbo Roaming technology, a wireless access controller that can achieve less than 50 ms roaming on three channels. This advanced roaming capability securely hands off clients at speeds so high that wireless clients may roam between APs almost seamlessly, with virtually no interruption in connectivity.

Maximum Availability 

  • Sub-50 ms Turbo Roaming
  • Configuration back-up
  • Dual redundant DC power inputs

Advanced Security

  • IEEE802.1X/RADIUS supported
  • WPA/WPA2/802.11i supported
  • Integrated DI/DO for on-site monitoring and warnings

White Paper:

Truly Uninterrupted Train-to-Ground Communications with Sub-50 ms Turbo RoamingDownload

The architecture of 802.11 ground to train data communications requires technology that can provide uninterrupted data streams for the onboard requirements. This white paper discusses the solutions to maintain seamless connectivity at high speeds through such technology as Moxa’s Turbo Roaming deployed with Wireless Access Controllers (WACs), specialized handoff parameters that can be effectively tweaked, and multiple redundancy measures to provide failsafe data links.
