NB3701-2Wac – EN50155 Railway Router with Dual WLAN-ac by Hirschmann, a Belden Brand

The Hirschmann NB3701-2Wac is a multi-service EN50155-certified on-board railway router designed around dual WLAN-ac radio modules, providing simultaneous dual-band Wi-Fi access for passenger and operational wireless connectivity on light rail and mainline railway vehicles. Developed within the NetModule product portfolio under the Hirschmann brand, the NB3701-2Wac is a proven and well-established platform that rail operators and rolling stock integrators across Europe have deployed extensively for on-board Wi-Fi passenger services, wireless device connectivity for CCTV systems, ticketing terminals, maintenance computers, and driver advisory systems. The dual WLAN-ac configuration enables independent radio operation on separate frequency bands, supporting passenger-facing public Wi-Fi on one radio while simultaneously providing secure operational wireless networking on the second radio, without requiring separate hardware for each function. This consolidated single-device architecture reduces installation footprint, power consumption, and system complexity in space-constrained rolling stock environments. EN50155 certification covers the full range of environmental, electrical, and mechanical requirements mandated for railway electronics installation, including the temperature cycling, vibration, humidity, and EMC performance demanded by European railway operators and certification bodies. The NB3701-2Wac suits trams, light rail vehicles, regional trains, intercity trains, and metro rolling stock deployments throughout Nordic, Baltic, and Central European rail networks. With a 5-year hardware warranty and an established field track record, the NB3701-2Wac represents a reliable and cost-effective choice for operators seeking EN50155 dual WLAN connectivity.
