Teldat APR2044ax

Railway Access Point for WiFi services on all trains

  • Wi-Fi 6 Multi-User-MIMO 4x4 for up- and down link
  • 2,4 Gbit/s @ 5GHz and 1,1 Gbit/s* @ 2,4 GHz
  • 802.11ax technology for 2,4 and 5 GHz band
  • Compliant with Railway Regulations
  • Integrated Bluetooth for IoT applications
  • 8 antennas for optimized coverage and performance


The APR2044ax is Teldat’s new WiFi Access Point for
railway applications. It features two state of the art WiFi 6
modules that can provide connectivity to a high number of
passengers. It’s especially designed to meet the more
demanding railway regulations (such as EN 50155). The
APR2044ax seamless integrates with HotSpot and
WebFilter applications, creating a full solution for on-train
Internet connectivity. With two 2.5GbE ports It has the
ability to be mounted on a daisy chain configuration which
reduces the need of additional switches.
