Open 5G Stand Alone Campus Network for a 5G Testbed in Bavaria

Planning and realisation of an open and flexible system and network architecture

Together with its partner siticom , FMBE is implementing a self-sufficient 5G stand-alone campus solution for a 5G testbed in Bavaria for a leading German research institute. In this realistic mobile communications environment, companies will be able to simulate and evaluate their industrial applications for the new 5G mobile communications standard. For this purpose, the FMBE and siticom are bundling their competences to provide an open 5G Stand Alone Campus solution with native cloud technologies.

FMBE planned and implemented the RF network in the licensed 3.7 GHz range for private 5G applications indoors and outdoors, including the installation and integration of the radio units.
To ensure the necessary network quality for future Industrial Internet of Things (IIoT) applications, the RF network design was software-supported, including level planning, calculation of the RF coverage quality and simulation of the propagation simulation in 2D and 3D. This is essential for Industry 4.0 applications, especially in machine-to-machine communication, as one is confronted with signal effects such as reflections, diffractions, refractions or scattering at machines, shadowing as well as a higher attenuation behaviour in this frequency range. In order to ensure sufficient coverage quality at every location, i.e. in the case of a drone even outdoors at a height of several metres, a highly available RF network design is critical.

Together with siticom, which provides a cloud native 5G core system architecture and multi-access edge computing infrastructure to deliver an edge computing platform with maximum flexibility, the partner companies created an open system and network architecture that meets the requirements for testing a wide range of Industrial Internet of Things (IIoT) applications in practice.
