Manufacturers, technology providers, and national and regional governments have invested billions of dollars in connected and autonomous vehicle research, pilots and demonstrations. Underlying the potential success for these important life-saving technologies is the need for communications infrastructure and interoperability. The questions invariably remain: what communications technology best serves the most? Who will build the infrastructure on which it will operate? Who will pay for it? Building that infrastructure will, in large measure, be the responsibility of the private sector pursuing communications business opportunities.
