"CAD" stands for Comuter Aided Drawing. It helps in creating massive piles of drawings, as people love it since it has been absolutely great. As a starter, you can read more about it
Modern vehicles are no longer just machines on wheels. Through Vehicle-to-Everything (V2X) communication , they are becoming active participants in intelligent transport systems, enabling safer driving, smoother traffic, and progress toward automation. DSRC: The First Step The earliest V2X technology was Dedicated Short-Range Communications (DSRC) , based on IEEE 802.11p. Operating in the 5.9 GHz band , it allowed onboard units (OBUs) in vehicles to exchange safety and infotainment data with roadside units (RSUs) . While DSRC was effective for short-range messaging, it faced limits in coverage, data rate, and quality of service (QoS) . These challenges motivated researchers to explore new solutions. D2D and the Cellular Shift A key breakthrough came with Device-to-Device (D2D) communication , where vehicles exchange information directly without always relying on infrastructure. This reduces latency, eases network congestion, and helps maintain reliability in crow...
