The AIROC™ automotive portfolio of industry-leading Wi-Fi® and Bluetooth® combo solutions power the Infotainment and Telematics systems in today's connected cars. AIROC™ automotive connectivity solutions allow drivers and passengers to easily sync and stream content from mobile devices to the car's infotainment system and rear-seat displays, while enabling high-speed connectivity beyond the vehicle.

Infineon’s pioneering Real Simultaneous Dual Band (RSDB) solutions provide simultaneous operation in both 2.4GHz and 5GHz bands as well as Multiple-Input Multiple-Output (MIMO) support. RSDB solutions provide the necessary bandwidth and the software architecture required to support complex use-case scenarios for cars, enabling combinations of AP, Station, and P2P connections simultaneously. This allows Automakers to support several simultaneous application scenarios: Driver and passenger devices streaming high-bandwidth data and media content, mirroring phone/tablet displays (Apple CarPlay, Android Auto, and Mirrorlink), and external Wi-Fi hot-spot access for on-the-go connectivity without relying on cellular data service. All this while using Bluetooth hands-free calling with the integrated Bluetooth technology that provides coexistence support for shared Wi-Fi and Bluetooth operation in 2.4GHz band.

Automakers can leverage in-car Wi-Fi to deliver software upgrades and new features. Drivers can use a mobile device to check remotely on their car's location, gas levels and mileage. The same device can receive alerts about vehicle performance and diagnostics.

Wi-Fi is the communication technology for Electric Vehicle (EV) charging infrastructure, both for optimizing energy-transfer from the electric grid to cars and to facilitate convenient payment systems for car battery charging.

The AIROC™ automotive-qualified Bluetooth devices enable connectivity between the car and the latest mobile devices and wearable gadgets. Support for Bluetooth's Enhanced Data Rate (EDR) enables best-in-class wireless audio for hands-free calling and Advanced Audio Distribution Profile (A2DP) music streaming between a mobile device and the vehicle infotainment radio system. The portfolio supports narrow band and newer wide band speech capabilities with a variety of SmartAudio™ algorithms, including packet loss concealment and bit error correction. Bluetooth technology also enables drivers to use their smartphones to adjust seat, temperature, and infotainment settings while providing vital data on automotive performance and diagnostics.

All automotive qualified, Bluetooth devices offer an industry-standard Host Controller Interface (HCI) and can be used with almost any Bluetooth stack, operating system and host processor.
