‍

One of the key factors that contribute to the high-speed data transmission in V2V and V2I communication is the use of dedicated short-range communication (DSRC) technology. DSRC operates in the 5.9 GHz frequency band and allows for the exchange of information between vehicles and infrastructure within a range of up to 300 meters. This technology enables vehicles to send and receive data at high speeds, ensuring that critical information reaches its destination without significant delays.

‍

Moreover, advancements in wireless communication protocols, such as 5G, have further enhanced the data transmission speed in V2V and V2I communication. With its low latency and high bandwidth capabilities, 5G technology enables vehicles and infrastructure to exchange large amounts of data in real-time. This is particularly crucial in scenarios where split-second decisions need to be made, such as when a vehicle is approaching an intersection or encountering a sudden obstacle on the road.
