Section: 7.2.3.2 Wireless road-side infrastructure backhaul
Content: Intelligent Transport Systems embrace a wide variety of communications-related applications that are intended to increase travel safety, minimize environmental impact, improve traffic management, and maximize the benefits of transportation to both commercial users and the general public. Road-side infrastructure such as traffic light controllers, roadside units, traffic monitoring in urban areas and along highways and streets is wirelessly connected to traffic control centres for management and control purposes. The backhaul communication between the road-side infrastructure and the traffic control centre requires low-latency, high communication service availability, and high-capacity connections for reliable distribution of data. Road-side infrastructure is deployed alongside streets in urban areas and alongside major roads and highways every 1-2 km. For more information about infrastructure backhaul, see clause D.5. To support wireless road-side infrastructure backhaul the 5G system shall support the performance requirements in table 7.2.3.2-1.
