Renesas Electronics Corporation, Murata Manufacturing Co, Ltd., and Ubiquitous Corporation today announced that they have started a technological collaboration on development of high-speed network connection technology targeting the IVI (In-Vehicle Infotainment) market, which is expected to expand in coming several years led by the progress of IT and networking and the accelerated adoption of cloud computing system.

With the explosive spread of smartphones, there is a growing demand for network servicing also in automotive environment. Amidst this situation, standardization of connection between smartphone and IVI is in progress and such technology is assumed to be more complex and high performance in the near future. Therefore in the state-of-the-art IVI platform, high-performance network OS (operating system) originally used in information system is more likely to be adopted instead of the OS dedicated to embedded system. Although these general-purpose, high-performance OS require certain amount of time for activation, quick start-up of the system is strongly demanded for quick display of back camera or quick output of radio sound. Assuming that high-speed Wi-Fi linkup between IVI and smartphone would be essential for comfortable use of in-car network servicing, Renesas, Murata and Ubiquitous have come to collaborate in creating a platform solution leveraging their advantages of respective technologies.

Trend of IVI Network Support

As the popularity of the smartphone grew rapidly, adoption of in-car network servicing system has been eagerly considered. Meanwhile, implementation of Wi-Fi system to IVI is about to go into stride and the average annual growth rate of the implementation is expected to grow rapidly.. Some of the smartphones now comply with the IEEE802.11ac, the next-generation standard succeeding the IEEE802.11n, and the IEEE802.11ac standard is now expected to be adopted to automotive environment.

The high-speed throughput realized by the IEEE802.11ac standard not only contributes to a comfortable network servicing, but also enhances automotive infotainment system by enabling smooth replay of movie contents such as Miracast. Moreover, the IEEE802.11ai standard is expected to play a part in improvement of user convenience with quick initial connection and authentication.
