RF Systems

Enable wireless connectivity

In the RF Systems research division, the focus is on innovations in relation to wireless communication and radar technologies in the radio-frequency spectrum from MHz through to the very high GHz range. RF systems provide the connection over the air for wireless communications systems (incl. RFID, WPAN, LPWAN, 4G/5G). This enables mobile broadband connection of mobile devices (such as smart phones, tablets and laptops), wireless “machine-to-machine” communication (M2M) that connects billions of IOT devices and increasingly wireless sensor networks in industrial applications. RF systems in the GHz range are also used for radar systems, which are a key element for autonomous driving, but also increasingly used in medical systems and material testing.
