Intelligent Wireless Systems

The “Intelligent Wireless Systems” division focuses on innovations in wireless communication and radar technologies across the frequency spectrum ranging from MHz to the very high GHz range. RF systems provide wireless connectivity for wireless communication systems (including RFID, WPAN, LPWAN, and 4G/5G). This enables mobile broadband connectivity for mobile devices (such as smartphones, tablets, and laptops), wireless “machine-to-machine” (M2M) communication—which connects billions of IoT devices—and, increasingly, wireless sensor networks in industrial applications. RF systems in the GHz range are also used in radar systems, which are a key component of autonomous driving, but are increasingly being used in medical systems and materials testing as well.
