Implementing Passenger Wi-Fi Networks: Five Key Considerations

Onboard Passenger Infotainment

  • Wireless Broadband

    Passengers can move around freely without losing Internet access because the AWK-3131A-M12-RCC wireless access points provide connection speeds of up to 300 Mbps.

  • Full-GbE Backbone

    The TN-G6512 switch has 12 Gigabit ports to meet the increasing bandwidth requirements of passenger services and to enhance operational efficiency.

  • Seamless Mobility

    UC-8580/UC-8540 computers feature GPS, multiple dual-SIM card slots, and intelligent WAN routing that includes Wi-Fi and cellular connectivity, to ensure seamless train-to-ground communications.

  • Media Servers

    Powered by an Intel® Core™ processor, the V2400A Series is ideally suited for streaming on-demand video infotainment.

Broadband Wi-Fi Access

Moxa’s AWK-3131A-M12-RCC 802.11n access points provide onboard wireless Internet to passengers, supporting up to 60 device connections with 2 Mbps connections to provide a superior multimedia experience.

The AWK-RCC Series supports wireless client isolation through packet filtering to disable communications between Wi-Fi clients associated to access points. This provides an added layer of protection against passengers gaining access to other devices for malicious purposes.

To ensure reliable connectivity, the AWK-RCC Series Wi-Fi access points are equipped with M12 and QMA connectors, and are designed in accordance with the mandatory sections of the EN 50155 standard to withstand vibrations, shock, and electrical noise on moving trains.


  • Wi-Fi access with connection speeds of up to 300 Mbps
  • Connect up to 60 concurrent devices per access point
  • Reliability ensured by anti-vibration connectors, dual power inputs, and dual isolation on power and antenna inputs

Full-Gigabit Train Backbone

Higher bandwidth supports faster communications and more passenger services. The compact TN-G6512 switches have 12 Gigabit ports, 8 of which can supply PoE+, to facilitate a full-Gigabit backbone infrastructure that makes it easy to integrate more multimedia applications and PoE devices in space-limited train car environments.

TN-G6512 switches come with millisecond-level redundancy and are designed in accordance with the EN 50155 standard to provide protection against vibrations, surges, and EMS to guarantee availability and reliability for train backbone operations.


  • Full Gigabit speeds
  • Compact size for easy installation
  • 8-port PoE switches to simplify connection of PoE powered devices
  • Network recovery time under 50 ms
  • Reliability ensured by push-pull M12 connectors and an IP67-rated enclosure
  • Cybersecurity features based on the IEC 62443 standard

Seamless Train-to-Ground Communications

Passengers can use their laptops and handheld devices to keep in touch with their friends, family, and office with reliable onboard communications provided by the Moxa UC-8580/UC-8540 gateway computers, which include GPS and dynamic routing for seamless connectivity over Wi-Fi and 4G LTE for train-to-ground communications.

Based on MIRF 2.0 (Mobile Intelligent Routing Framework) firmware, the dynamic routing feature enables switching between WANs, ISPs, and telecom carriers as the train travels through different regions.

Both computers support VLAN and VRRP for network load sharing. VRRP also enables master/backup router switchover for redundant connectivity.


  • Built-in GPS, Wi-Fi, and multiple 4G LTE modules for versatile Internet connectivity
  • Optimize WAN connectivity through dynamic routing
  • Dual-SIM support for each 4G LTE module to prevent downtime if one SIM in a module fails
  • Compact and single-sided I/O wiring for easy installation
  • Anti-vibration M12 connectors for increased reliability

Media Servers

The V2406A computers are media servers that are specifically designed for the rail industry that support high-speed downloads for on-demand entertainment services.

The compact and robust computers come with 1 SATA connector/slot, 2 CFast sockets, and dual Gigabit ports to store and transmit large amounts of multimedia data for onboard infotainment.


  • 2 x HDD/SSD expansion slots for multimedia storage
  • Anti-vibration M12 connectors for increased reliability

Improving Onboard Wi-Fi to Enhance Passenger Satisfaction

Onboard Wi-Fi access while traveling has become key to increasing ridership for rail and metro operators. One of the biggest challenges to providing sufficient bandwidth for passengers is the complexity of retrofitting existing trains with interoperable network infrastructure. Moxa has over 400 rail-proven products to enable full Ethernet communications onboard moving railcars, which allow passengers to remain productive and entertained throughout their entire journey.

System Requirements

  • Stable Wi-Fi connectivity
  • Sufficient bandwidth for high-speed Internet access
  • Simplified network maintenance to handle daily inter-car and inter-consist changes
  • Easy, flexible, and reliable routing across various locations and IP service carriers
  • Durable devices and reliable network connectivity help ensure reliable operations
  • Compact size that fits into the space-limited environments on trains
