Some 1.2 million people are killed by car accidents every year and human errors(e.g. drunk-driving, speeding, ignoring traffic signals, texting while driving, etc.) are responsible for more than 90 percent of these fatal accidents. This loss of 1.2 million lives per year is equivalent to seven 500-passenger aircrafts crashing every day.To reduce the number of car accidents as close to zero as possible, carmakers,automotive suppliers, governments, academics, and even non-automotive technology providers are jointly developing Advanced Driver Assistance Systems (ADAS) and ultimately autonomous driving systems.
Two existing wireless communications technologies, Dedicated Short Range Communications (DSRC) and 4G-cellular LTE, are used in current and near-future automotive wireless communications. However, limitations in these technologies affect their suitability for mission-critical requirements for autonomous driving and advanced ADAS systems. Neither provide gigabit/s data rate, high-speed mobility support, massive machine communication, or ultra-reliable low latency. In this paper, we will learn how emerging 5G cellular communications solutions address the limitations of DSRC and4G-cellular LTE to truly deliver on the promise of a safer and enhanced transportation experience.
