Vehicles are about to become a lot more communicative: with other road users, with the infrastructure they pass on their journeys, with cloud-based services, and even with the energy grid. This communication should make vehicles more economical to operate, as well as enabling new capabilities.

Making such communication possible will mean solving a series of design challenges in a rapidly evolving regulatory environment and complex engineering context.

In the second installment of our automotive series, Martin Keenan explores the ways in which connected cars will communicate with other entities, available protocols, and key considerations for component selection.
