How the information flows
Crisis-relevant information is stored on the device, even without a network.
Warnings reach citizens via an independent radio network.
The crisis team can communicate even during a total outage.
Operated on a local server with emergency power supply.
Municipalities must be able to reach their citizens reliably in an emergency – during floods, power outages or cyberattacks. Yet that is exactly when all existing digital channels fail.
When the flood came, power, mobile network and landline failed. Many people received the warnings too late or not at all – exactly when they were needed most.
Without power and mobile network, warning apps fall silent, and websites and social media are unreachable. Citizens are left on their own, not knowing what is happening or what to do.
The crisis team in particular depends on reliable communication. If telephone, email and mobile network fail, situation reports can no longer be shared, decisions can no longer be agreed and measures can no longer be coordinated.
Ortsnetz is the municipal platform that serves as a complete citizen app in normal operation and switches seamlessly to a self-sufficient communication system in a crisis – without power, internet or mobile network.
A local server at the public utility coordinates all registered citizens, provides everyday and crisis information for download and synchronizes messages via the mesh network – on emergency power during a power outage.
A decentralized 868 MHz radio network connects all districts of the municipality and reliably delivers messages to citizens' devices – entirely without mobile network or internet. Self-healing: no single point of failure.
Dedicated devices in public buildings provide their own Wi-Fi and deliver all important information as a web app – access via QR code, no app installation required.
An optional satellite link of the hub server can bridge the connection to the outside world. In the future, aerial situation images are also to be available.
Four layers, one system: in everyday life Ortsnetz uses the usual networks, in an emergency your municipality's own infrastructure with emergency power supply.

The crisis team sees who or how many people have received and confirmed a message.
Group chat via the mesh network, logged in an audit-proof way.
All critical information and maps available even without a network.
Which expansion stage shall we discuss together?
Book a consultationYes. In a crisis, the mesh network carries the communication. The hub server and info points run on emergency power with at least 72 hours of autonomy, the solar-powered repeaters permanently. The network is self-healing: if a node fails, neighbouring nodes automatically reroute the message.
No. The app is the visible part. Behind it are a local server in your municipality, a dedicated radio network and devices on site, which together keep working even when no public infrastructure is available anymore.
The crisis team can communicate even during a total network failure, sees whether warnings have been received and has offline access to all stored crisis documents. Communication within the crisis team is recorded separately for documentation purposes.
All user data remains on the server in your municipality. There is no mandatory cloud and no disclosure to third parties. Transmission and storage are encrypted throughout; the architecture is designed for GDPR, KRITIS and NIS2 requirements.
