Dedicated short-range communications (DSRC) is a technology for direct wireless exchange of vehicle-to-everything (V2X) and other intelligent transportation systems (ITS) data between vehicles, other road users (pedestrians, cyclists, etc.), and roadside infrastructure (traffic signals, electronic message signs, etc.). [1]

The DSRC Service involves vehicle-to-vehicle and vehicle-to-infrastructure communications, helping to protect the safety of the traveling public. It can save lives by warning drivers of an impending dangerous condition or event in time to take corrective or evasive actions.

What is DSRC? DSRC (Dedicated Short-Range Communications) is a wireless communication technology that enables vehicles to communicate with each other and other road users directly, without involving cellular or other infrastructure. DSRC is based on WiFi technology.

DSRC and C-V2X are technologies used for very high-speed and high-frequency data exchange (up to 10 times per second with millisecond latency). This communications infrastructure can enable red-light running warnings, rear-end crash protection, curve speed warnings, road weather warnings (like black ice), eco-driving, and personalized traveler ...

May 22, 2019 · Dedicated Short Range Communication (DSRC) is an 802.11p-based wireless communication technology that enables highly secure, high-speed direct communication between vehicles and the surrounding infrastructure, without involving any cellular infrastructure.

May 18, 2023 · DSRC is an IEEE 802.11p-based WAVE technology, developed from standard Wi-Fi specifically for automotive and transportation applications. DSRC uses WLAN technology to establish short-range communication between vehicles and infrastructure, allowing them to send and receive information directly.

DSRC is a wireless communication technology that enables fast and secure data exchange between vehicles and roadside infrastructure. DSRC can support various applications for road safety, traffic management, toll collection, parking guidance and more.

DSRC Basics Dedicated Short-Range Communications The “commonly” deployed V2V technology Used in European Union, the US (very limited, <0.0057%of the 274 million vehicles on the road), and Japan Based on Wi-Fi technology (IEEE 802.11p or 802.11bd) Layers 1 & 2 (PHY and MAC) Network/transport layers and security: IEEE 1609 family

DSRC uses orthogonal frequency division multiplexing (OFDM), sometimes based on the wireless local area network (WLAN) standard known as the IEEE 802.11a standard. In a direct comparison with IEEE 802.11a, the DSRC has robust interference sturdiness and can adapt to continuous and fast transition conditions.
