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 (Dublin, Athens, Luxembourg (city) and Valladolid). 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, reduce fuel costs and carbon footprint, enhance education, improve city experiences for tourists/cultural consumers and save patients’ lives. LiveCity underpins technology which has the ability to massively scale while it integrates the necessary ingredients in an efficient low-cost manner and provides a proper testing ground for a mass market deployment to the cities in Europe.
