Businesses with their own campus network benefit from a customized 5G network with guaranteed bandwidth, low latency and high reliability. Our mobile campus network provides companies with a simple and cost-effective way to find out in advance whether setting up and operating their own 5G campus network is worthwhile.
As the door of the ambulance closes, an invisible data gateway to the hospital is already opening. An initial emergency diagnosis of the patient’s health condition can be transmitted immediately via video conference to the hospital on the journey there. This means the relevant team in the ER department receives an initial medical assessment before the patient arrives and gains valuable minutes in which to prepare specific acute emergency measures.
To test the data transmission from an ambulance, we installed a temporary mobile campus network in Berlin as part of the Health5G project. This application scenario could subsequently be implemented in real-life operation with a network slice in the public 5G network; that is to say, a piece of the wireless network in which the data does not collide with that of other users. Just like the flashing blue lights in road traffic, so the transmitted data from the ambulance would also be given priority in the data traffic.
Currently, however, the only way to try out this prioritized data exchange between rescue services and hospitals is by using a mobile campus network.
Um die Datenübertragung aus einem Krankenwagen heraus zu erproben, haben wir im Rahmen des Projekts »Health5G« ein temporäres, mobiles Campusnetz in Berlin installiert. Dieses Anwendungsszenario ließe sich im späteren Realbetrieb mit einem Network Slice im öffentlichen 5G-Netz umsetzen, also einer »Scheibe« des Mobilfunknetzes, in der die Daten nicht mit denen der anderen Mobilfunknutzer kollidieren. Ähnlich wie beim Blaulicht im Straßenverkehr würden die gesendeten Daten aus dem Rettungswagen auch Vorrang im Datenverkehr erhalten. Ausprobieren lässt sich dieser priorisierte Datenaustauch zwischen Rettungsdiensten und Krankenhäusern derzeit aber nur über den Einsatz eines mobilen Campusnetzes.
Customized 5G campus networks with guaranteed available bandwidth
A campus network is a local 5G network that companies and other organizations can operate for their own use, independent of the public cellular infrastructure. In Germany, the Federal Network Agency makes the licensed frequency range of 3.7–3.8 gigahertz available for this purpose. This means that up to 100 megahertz of bandwidth are guaranteed available locally – for example, at the company site – for 5G applications at all times.
