Over the years, cities represented places with a large concentration of population. As cities tend to grow, they are eventually transformed into large centers of consumption. This leads to an increasing difficulty in organizing a city. As a result, local authorities need to find ways to increase their city’s efficiency by anticipating problems and coordinating resources in the best possible way. Therefore, the application of information technology and communication (ICT) becomes essential and is reflected in the Smart City concept. Some of the areas that smart cities focus on are urban mobility, energy efficiency, management of resources, management of the city’s infrastructure, public safety as well as health, culture and education. However, the real challenge is the ability to achieve the aforementioned in a realistic and coordinated way. Until today, many projects of real smart cities have been carried out across the globe having a common goal: to solve real problems, give smart support to their infrastructure and improve quality of people’s lives. The main aim of this Thesis is to present the concept of smart cities, identify the initial steps that need to be taken by a city towards this direction, using a real case scenario and highlight the benefits involved as well as propose a business model that will assist in such a transition. In more detail, the most important characteristics and applications are presented along with the benefits applied to citizens, businesses and public authorities in a smart city environment. Moreover, the benefits associated with PPPs are examined along with financing options for smart city developments and a business model is proposed. Finally, different Wi-Fi network implementation scenarios for the municipality of Kalavrita are evaluated, resulting in the costs associated with the specific implementations as well as the formation of a viable proposition for the assumption of such a deployment by a private company.
