WAC-2004

Industrial wireless access controller

Features & Benefits

  • 2-in-1 AP controller and mobile IP home agent
  • Millisecond-level controller-based Turbo Roaming
  • IEEE 802.11i-compliant wireless security
  • Layer-3 mobile IP technology
  • Up to 450 Mbps throughput for tunneling

Introduction 

The goal of zero-latency roaming is to allow clients to seamlessly maintain their communications as they move from one access point to another. The advanced Moxa Wireless Access Controller, the WAC-2004, together with Controller-based Turbo Roaming technology, enables millisecond-level roaming over different IP subnets. The
advanced roaming algorithm along with Mobile IP technology allows wireless client to roam between APs in different IP subnets within milliseconds while upholding stringent security in extremely demanding environments. The WAC-2004 is rated to operate at temperatures of 0 to 50°C and is rugged enough for on-site installation in any harsh industrial environment.

  • Device-level redundancy via hot standby controller

Minimum Handover Time

  • Millisecond-level Turbo Roaming
  • Inter-controller roaming

Maximum Mobility in L3 Networks

  • Mobile IP tunneling
  • Care-of-Address (CoA) assignment

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.
