Efficient communication, cost-effectively implemented.

Network & Communication


SITA Airport IT GmbH offers network services for all lessees on the Düsseldorf Airport campus. These include air operations, airlines, administration, airport concessionaires, ground handling services, cargo and catering organisations as well as commercial areas, including retail companies from a wide variety of sectors.

The airport network includes the terminal building as well as cargo, hangar and administrative areas across the entire campus. It offers the flexibility of wired and wireless services, both on the land side and air side of the airport.

As the airport is a multi-customer environment, security and the separation of traffic and services between the different lessees is of crucial importance.

SITA Airport IT provides a secure, flexible and fast network for your customers.

Gateway into the airport network

If access to the airport's secured systems – such as the AODB flight database or the FIDS flight information – is required from a customer’s network, a gateway that is protected by a firewall will be activated. This can be done via a defined router/firewall access on campus or be provided using corresponding VPN technology.

Router/Firewall connection

Virtual firewall services can be made available in order to secure customer networks.

Remote Access and LAN-to-LAN VPN

Thanks to VPN/IPSec technology (Virtual Private Network), confidential data can be exchanged securely and easily via the Internet. Mobile users are able to access internal airport services. It is also possible to provide LAN to LAN couplings after corresponding scrutiny.


The latest technologies enable scalable and individually tailored networks as well as high-speed connections in our data centres.
