Nowadays, the deployment of  Smart City biggest challenge  is to find a solution that allows a fast and cheap service/equipment rollout. Cities need to have a global view of the services they need and where and when they need them, in order to plan a global rollout or to deploy base infrastructures. Since a global rollout plan is something almost impossible to achieve (investment, clear view of service needs, available technology and management solutions, amongst other reasons). Cities should start thinking in deploying a base infrastructure that allows service/equipment integration, utilities sharing, and that is technological agnostic. This will allow them to reduce service/equipment deployment time and cost. And will have the advantage to integrate any existing or future equipment with minimal or no impact. This is a big concept change, nowadays everybody thinks about technology but no one is thinking how implement it in the real world in a massive way. Cities have limited budgets therefore they need to have a first smart decision, a modular, upgradable and technological agnostic base infrastructure. And of course, an associated business model to make it sustainable.
