Overview

The R-Car W2R is a system on chip (SoC) for automotive wireless communications that supports 5.9 GHz band vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications compliant with the IEEE-802.11p communications standard for Intelligent Transportation Systems (ITS) used in Europe and North America. Through the use of Renesas' exclusive RF system design technology, the R-Car W2R is the first in the world to succeed in suppressing out-of-band transmission signal noise below the -65 dBm stipulated by the European Telecommunications Standards Institute (ETSI). This makes it possible for products that use the R-Car W2R to achieve the best noise characteristics in the world. This enables high-quality signals with little interference to be transmitted, making it possible to implement vehicle-to-everything (V2X) at a practical level in various kinds of ADAS systems for supporting safe driving.

• Helps reduce system size by integrating all communication functions, from IEEE-802.11p-compliant RF to physical layer and data link layer, on a single chip
• Small module reference design optimized for external RF components helps speed up development cycle
• Exclusive RF system design realizes world's best out-of-band transmission noise characteristics
• Combo V2X starter kit with R-Car E2 facilitates software development and verification testing
