The NetModule NB2700-UW-G is a vehicle router specifically developed for use in mobile environments such as buses, trucks, or other transport vehicles. It enables internet access via UMTS and LTE networks and features an integrated access point, allowing passengers and vehicle personnel to connect WLAN-enabled devices such as notebooks, smartphones, or tablets. At the same time, the router provides operational remote access to vehicle systems, which is important for maintenance, monitoring, and diagnostics. The E1 certification allows for direct integration of the router into new vehicles at the factory, simplifying installation processes and ensuring compliance with vehicle standards.

Applications

The router is primarily designed for use in public transport, logistics vehicles, and other mobile applications where a stable, secure, and user-friendly network connection is required. It supports the provision of WLAN for passengers while simultaneously enabling the transmission of operational data via mobile broadband connections. The ability to use two mobile broadband connections in parallel allows for load balancing or assigning specific applications to specific connections, optimizing bandwidth and reliability.

Functions and Equipment in Detail

The NB2700-UW-G features an RS-232 serial interface, which can be used either as a serial device server or as a system console. This interface can also be controlled via the SDK environment, enabling flexible integration into existing systems. Additionally, two isolated binary inputs and two relay outputs are integrated, which can be used to control sensors and actuators. The logic for these inputs and outputs is programmed by the user in the SDK environment, allowing individual adaptation to specific requirements. The USB port is used for quick configuration and firmware updates via a memory stick, but can also be configured as a device server.

Technology Explained Simply

The router firmware supports common VPN technologies such as OpenVPN, IPsec, and PPTP, with both client and server modes available. This enables secure, encrypted connections between the vehicle and a central network. Managing a Public-Key Infrastructure is easily possible via the user interface, allowing two NetModule routers to be connected via a secure VPN tunnel with just a few steps. Additional services include a DHCP server, DNS proxy server, DynDNS agent, SNMP agent, Telnet/SSH server, web server, email client, and SMS client. Device management is performed via an intuitive web interface or command line.

Compatibility and Accessories

The router is compatible with suitable accessories such as the NB25er series, designed for integration into vehicles. The NB25er series serves as accessories for mounting and integrating the router into vehicle environments.

Mounting and Installation

Installation is carried out in vehicles, with the E1 certification enabling direct integration at the factory. Mounting typically takes place at an accessible location within the vehicle, taking into account connections for Ethernet, USB, serial interface, as well as relay and input interfaces. Configuration is performed via the web interface or command line, with firmware updates possible via USB or over the network.

Operational Advantages

Operation of the NB2700-UW-G offers a combination of mobile internet connectivity, WLAN availability for users, and operational remote access. Support for two mobile broadband connections increases reliability and enables flexible usage. The integrated interfaces and SDK support allow individual adaptation to specific requirements. Security features such as VPN and Public-Key Infrastructure ensure protection of sensitive data. Management via web interface or command line offers flexibility in operation.
