A Square Kilometre of Private 5G at Altenwerder
Deutsche Telekom and Ericsson have built a private 5G campus network over HHLA's Container Terminal Altenwerder in Hamburg, covering one square kilometre on 3.7–3.8 GHz.

Deutsche Telekom and Ericsson have deployed a private 5G campus network at Container Terminal Altenwerder, the HHLA-operated facility in the Port of Hamburg. The network covers one square kilometre on Germany's 3.7 to 3.8 GHz industrial spectrum and is intended to connect cranes, trucks, sensors, mobile devices and IT systems in real time. Klaus Werner of Deutsche Telekom described it as taking the digitalisation of port logistics to the next level with HHLA, and HHLA's Michael Albers framed it as a high-performance and reliable wireless infrastructure for testing new applications under realistic conditions. The deployment lands in a port with a long private-network history: Nokia and Deutsche Telekom ran 5G slicing trials with the Hamburg port authority in 2019 under the EU's 5G-MoNArch project, and Deutsche Telekom won a €6.6 million project for private 5G at the separately operated Eurogate terminals in 2023.
The seven-year gap between the first trial and this deployment is the part worth reading carefully, because it is typical rather than unusual. Container terminals are among the most frequently cited private-5G use cases and among the slowest to convert, for reasons that have little to do with radio: the equipment is long-lived, the automation already works on something else, downtime is unusually expensive, and the business case has to beat an incumbent Wi-Fi or licensed-narrowband system that is paid for and understood.
What makes a terminal genuinely well suited is a specific set of properties rather than the obvious one of size. The site is privately controlled, which makes local spectrum straightforward. It is dense with metal and moving structures, which is where Wi-Fi roaming suffers most. The devices are high-value and mobile — a crane, a straddle carrier, an automated guided vehicle — so a per-device cost that would be prohibitive on a sensor fleet is immaterial. And latency and handover reliability translate directly into container moves per hour, which is a number the terminal already measures in money.
For industrial operators weighing the same decision, the transferable question is whether the applications on the network are ones that fail badly on Wi-Fi. Mobility across many access points, deterministic handover, and predictable uplink for machine control are the honest reasons to choose private 5G. Coverage area and device count alone are not; a square kilometre of yard is well within what a properly engineered Wi-Fi network covers, and the advantage in Hamburg is in the behaviour of the link under movement, not in its reach.
