THE WAY TO 6G
Research projects at SAL in the mm-Wave/RF domain are targeting technical innovation for beyond 5G future wireless communications networks. The research team, headed by Gernot Hueber, develops specific backhaul/fronthaul application and devices operating in the 300 GHz frequency bands. Bitrates exceeding 100 Gb/s, cost-efficiency, high spectrum and power efficiency are the main features of the next generation RF front-ends. These features will be enabled by the key technologies, which are developed in SAL research projects.
High-performance systems with low maintenance costs
System topologies and RF components will be the key elements within the development envisaged together with project partners in the EU. A scalable and modular system architecture including packaging will enable cost-effective mass production of 300 GHz lens array antenna front-ends. The parallelization of data streams using multiplexing architectures such as line-of-sight MIMO, frequency carrier aggregation and polarization multiplexing will boost energy and spectral efficiency. A novel beam alignment concept by using agile lens antennas allows automatic adjustments during life time, resulting in a significant reduction of installation/maintenance cost. By considering the design of the complete architecture, from antenna down to baseband, a high-performance system is guaranteed as research outcome.
The power of sub-mm-Wave communication platforms
SAL will focus on beyond 5G scenarios: backhaul (point-to-point), fixed wireless access (point-to-multipoint), and access networks in crowded scenarios (point-to-multipoint). Demonstrations addressing these three scenarios will clearly show, how powerful and flexible the sub-mm-Wave communication platforms are.
