Approach1) Maximise existing
network benefits 2) Invest for clear benefit3) Hypothesis & Scenarios
Government Users
SwarmUbiquitous 4G 5G/Non-Cellular
Communication
Government(Central & Local)
Users(Travelers, Operators, OEMs)
Infrastructure(MNOs, HWE, …)
Hypothesis
“Ubiquitous 4G cellular coverage is sufficient to deliver
many of the benefits which will be realised through
Connected Vehicles.”
Scenarios

Safety critical driver assist and automation functions require immediate response, but only over a local area with low range
Journey Planning requires broad coverage, over the
greatest range, but latency is not critical
In vehicle productivity and traffic management need a balance of latency and
coverage to provide viable service level
