Wireless vehicle control : A study of the application of 5G
In this day and age, with highly available and fast networks, many tasks are being performed remotely. However, certain tasks cannot be flawlessly executed remotely, for instance, the tasks performed by professional drivers. Their jobs demand a lot of visual cues, fast actions, and low response time...
