Press Release

IRVINE, Calif —Thurs, December 5, 2013, 8 AM EST (5AM PST) -- Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced a new Automotive Bluetooth® software stack, enabling seamless in-car connectivity with Android-powered devices.  As an extension to the company’s Bluetooth software stack (Bluedroid) contribution to the Android Open Source Project (AOSP), Broadcom’s Android Automotive Bluetooth software stack ensures seamless, end-to-end interoperability between in-car applications and mobile Android devices.

Android has captured ~80 percent market share in global smartphone shipments(1) and demand for automotive device connectivity is on the rise. Until now, the fragmentation of Bluetooth software has resulted in poor audio performance and interoperability barriers across a range of devices. Broadcom's Android Bluetooth software removes these barriers, delivering a significant improvement in audio quality for hands-free calling and streaming music. Integrated Bluetooth Smart Ready technology syncs easily with wearable devices to monitor driver health and biometric indicators such as driver fatigue and blood alcohol content.

“The choice of in-vehicle technology is becoming more important as consumer demand for seamless mobile and wearable device connectivity continues to rise. Auto makers and tier one suppliers are looking for robust, feature-rich and flexible operating systems that are relatively painless and easy to deploy,” said Richard Barrett, Broadcom Director of Wireless Connectivity. “Our automotive Bluetooth software stack combines Broadcom’s proven expertise in software development and widely deployed wireless connectivity with high performance profiles optimized for use in the evolving automotive environment.”

“Open platforms continue their march forward in automotive with more and more car makers and tier one suppliers transitioning to open source platforms such as Android,” said ABI Research VP Dominique Bonte. “The automotive industry is set for a number of dramatic paradigm shifts and the adoption of open source platforms is just one example. In this regard, the automotive industry can mirror and keep pace with trends in mobile.”
