Golden opportunity to try out 5G

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.

The performance of a private 5G campus network can be tailored precisely to specific requirements of the planned applications. Usually this involves things like more data throughput, lower latency and utmost reliability in transmission. Anyone who wants to try out a campus network before investing in their own 5G infrastructure has a golden opportunity with the mobile campus network. Basically, this is a transportable testing environment for 5G that can set up a little 5G network for testing purposes practically anywhere.

Testing 5G applications directly at the site of the action

The mobile campus network consists of an antenna, a radio head and a local computer that fulfills the role of the 5G base station and the 5G core network. As such, the equipment is compact and can be set up quickly and easily on a few square meters. A 5G cell is erected with a range of up to a few hundred meters and can be used both in buildings and outdoors.

Meanwhile, there are fixed testing installations for 5G that can be used for comprehensive performance tests. In venues such as the factory floor, company premises, construction sites, event locations and farm settings in particular, it is often important to test 5G specifically in the place where it will later be used. This renders the benefits of 5G directly visible in the concrete application case. A good example is the For5G project, in which we are involved, where 5G is used in cherry farming to transmit images of the cherry trees taken by a drone. Using the transmitted image data, digital twins of the trees are created, which help monitor their health and develop yield forecasts. In this project, our mobile campus network provides the requisite – but not yet available on-site – 5G coverage, which makes it possible to transmit the image data from the drone to the network in the first place.

Full network load ahead

The mobile campus network opens up detailed insights into the performance capabilities of wireless transmission. With a 5G load generator, additional data traffic is generated in the network. It increases virtually, so to speak, the number of devices transmitting in parallel in the campus network. As a result, it is possible to investigate the effect of the network load on the performance of planned applications. This makes it clear from the beginning whether an application will work without problems even when the network is working at full capacity, and whether installing a permanent campus network is worth it.

For further detailed analyses, we can carry out supplementary investigations at our 5G Bavaria Industry 4.0 test bed. The test bed allows us to conduct a more comprehensive range of tests with more configuration options in a full-performance campus network with on-site industrial equipment.

Test phase is just the beginning

After intensive testing, it is a matter of utilizing the results and taking them into account when, for example, a company wants to build its own campus network. After all, 5G creates new opportunities in all sectors for further developing products, systems and processes in highly innovative ways. And our commitment to the task extends far beyond the testing of new 5G technologies: backed by our know-how from the development of wireless communication systems and current 5G standardization, we create concepts that illuminate the most suitable technological implementation possibilities for every use case. When it comes to concrete implementation, we offer companies ongoing assistance with 5G projects, advising them on the choice of suitable technologies and equipment and supporting them through technical coordination. Our goal is to help our customers get 5G up and running so that they can create improved products, services and processes that secure their competitiveness.
