5G and Beyond

With 5G, the performance of mobile communications has been significantly increased and taken to a new level. The new generation not only offers higher data rates, but also enters completely new areas, paving the way for applications that were previously unthinkable. Particularly for industrial and vehicle communication as well as the Internet of Things (IoT), the intelligent connecting of objects offers the opportunity to further develop products, systems and processes in innovative ways.

As an application-oriented research institute, we close the gaps between standardization and application by combining research, standardization work and testing in practical applications. This means we are involved in all phases of establishing 5G and are actively shaping the mobile communications standard. We also support and advise the industry in the development and implementation of new and future 5G technologies.

Ultra-short latency of less than one millisecond, exceptional transmission rates of over 10 Gbit/s and globally available wireless connections: These strengths make 5G a true multitasker. Compared to its predecessors, the mobile communications standard offers a significantly higher degree of flexibility and therefore always remains adaptable in practice. From applications that require extremely high bandwidths, to time-critical processes that depend on real-time capable radio, to IoT products that rely on a massive number of connected devices: 5G has the appropriate and tailored solution in its repertoire for every requirement.

The global 5G network is currently still in the developmental stage. However, the mobile communications standard already offers a large pool of solutions that can be used to address a wide variety of application needs.

5G technologies for diverse applications

5G requires completely new transmission and network concepts. We want to use the flexibility of the 5G standard to develop customized solutions that are tailored to the individual needs and conditions of the industry. That’s why we have specialized our expertise in wireless communication and localization in specific application areas.

Non-Terrestrial Networks

Non-Terrestrial Networks

With the establishment of 5G, satellites are for the first time being consistently considered as an integral part of the communication infrastructure. Terrestrial and satellite-based systems merge into hybrid networks. These are intended to help expand global coverage and maintain mobile communications even under difficult conditions. One option is to connect terrestrial base via satellite to the core network (backhauling). Another way of intelligent networking is 5G Direct Access. Here, 5G-capable smartphones or vehicles can directly communicate with satellites. With new on-board processors - such as the Fraunhofer On-Board Processor (FOBP) - satellites can also be configured in such a way that they function as 5G mobile base stations providing broadband internet to remote regions, aircraft and ships.

To drive the integration of satellites into the 5G generation, we have developed a simulator for Non-Terrestrial Networks. This enables satellite manufacturers and operators to virtually reproduce the trajectories that can be expected in hybrid networks and thus predict the expected performance. The forecast parameters include, for example, the coverage area or maximum throughput. If, on the other hand, applications need to be tested directly in the field and at an early stage, our demonstration platform is used, which is suitable for both GEO and LEO satellite transmission tests.

Benefit from our 5G skill set

The introduction of 5G technologies requires a well-founded approach due to the complexity of the topic and the numerous influencing factors. With our expertise from research into wireless communication systems and our activities in ongoing standardization, we help companies find the optimal 5G strategy. Additionally, we are at your side when it comes to the actual implementation by adapting your technologies to specific solutions and developing suitable prototypes. In the setup, operation, and use of 5G networks, we rely on many years of experience with our automotive test bed in Rosenheim.

Coexistence Study for the Evaluation of LTE/5G FDD and 5G TDD Scenarios

commissioned by: Vodafone GmbH

The goal of this study is to analyse the coexistence of an existing 4G/5G Mobile/Fixed Communication Network (MFCN) and the planned 4G/5G network for trains, called the Future Railway Mobile Communication System (FRMCS), also known as Railway Mobile Radio (RMR) in 3GPP context. Our study examines the conditions under which both networks can coexist with minimum interference effects.
