Urgently needed spare parts, laboratory samples or medicines must reach their destination as quickly as possible. Morpheus Logistik speeds up such deliveries using networked drones, which are highly automated and can even fly over traffic jams in low-altitude airspace. The control centre in Dortmund requires a stable mobile network connection at all times for position data, video feeds and optional interventions in the control system. This connectivity must function reliably even over longer distances, in cities or in regions with variable network coverage. Furthermore, regulatory safety requirements mandate a secure fallback solution.
