On April 23rd, Dr. Gernot Hueber, Head of Re­search Unit RF (= Radio Frequency) at Silicon Austria Labs (SAL), gave a lively talk on tech­nical inno­va­tions for beyond 5G wire­less commu­ni­ca­tion networks in Vienna. On this occa­sion, he deli­vered expert insights in SAL's inno­va­tion approach in the field of mm-Wave & Radio Frequency.

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.
