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.
