VANBw 1. Los

VANBw 1. Los (relocatable Bundeswehr access networks) provide in-field Bundeswehr forces with a local, network-compatible communications infrastructure. This handles all of the communications services and functions of a convergent network. VANBw provide subscribers with all of the functions needed to access networks. The particular significance attached to VANBw flexibility and availability under military field conditions is also and ultimately presented in its special distinction contrasting with conventional IT networks in a civil environment.


The system provides the subscribers with access to the network and serves as the local source of all the functions of a convergent network complying with public standards. It can then be used to handle all applications (e.g. central services, command and specialized information systems) on a standardized network.

One of the system’s core applications is VoIP, which depends essentially on IPv6. In-field links to the homeland are safeguarded over long-distance IP-compatible media. Transmissions make use primarily of satellite communications and radio relay systems. The system can link to any long-distance transmission system as a means to safeguard uninterrupted communication with the higher command levels.

Intended for use in crisis regions, these systems have been accommodated in operations, transport and storage containers certified pursuant to military standards. These containers (abbreviated officially as “BTuLB”) have been developed by the provider steep specifically for use under the most diverse climate conditions and provide IP54 protection when operating and IP64 protection during transport. One system consists of a core network module and at least five subscriber connection modules. A core network module consists of two identical submodules (“I” and “II”) and is therefore designed for 100 per cent redundancy. This redundancy enables the system to continue operating to full capacity even when one of the submodules fails. The core network submodules are interlinked likewise over redundant 20 Gbit/s optical waveguides. Fitted with a UPS module and a specially developed air conditioning unit, it is also operable under extreme climate conditions and can balance out or bypass power supply fluctuations for up to 15 minutes. In addition, it exhibits an extreme operating temperature range of -32 °C to +49 °C.

In addition to the BTuLB variant, VANBw are also available as cabin installations. Each of the components are mounted on racks, yet provide the same functions to the same extent as their BTuLB counterpart. When transported by truck, the transport and storage containers are loaded with their equipment remaining in the cabin.
