The LiveCity Project effort intends to create a city-based “Living Lab” and associated ecosystem to pilot live interactive high-definition video-to-video (v2v) on ultrafast wireless and wireline Internet infrastructure for the support of appropriate public service use cases among a number of city user communities initially in four major European cities. The essential aim is to empower the citizens of a city to interact with each other in a more productive, efficient and socially useful way by using v2v over the Internet, as the latter can be considered to improve city administration, enhance education and city experiences for tourists/cultural consumers and save patients’ lives. We discuss the role that stakeholders can play in identifying appropriate KPIs to assess the progress of the LiveCity concept, covering the underlying network infrastructure, the intended services-facilities per specific case, as well as users’ satisfaction and requirements.
