SmartSantander proposes a unique in the world city-scale experimental research facility in support of typical applications and services for a smart city. Tangible results are expected to greatly influence definition and specification of Future Internet architecture design from viewpoints of Internet of Things and Internet of Services.This unique experimental facility will be sufficiently large, open and flexible to enable horizontal and vertical federation with other experimental facilities and stimulates development of new applications by users of various types including experimental advanced research on IoT technologies and realistic assessment of users' acceptability tests.The facility will comprise of more than 20,000 sensors. It will utilise the results of two major EU-funded projects, SENSEI and WISEBED, in creating a secure and open platform of heterogeneous technologies.The city of Santander was chosen in response to offer of full support received from regional Government of Cantabria with real cash contribution of 500,000 €. Thereby strengthening their chance of winning the 2016 election of the city as the Cultural Capital of Europe.To efficiently achieve the goals of SmartSantander, three phases of deployments have been envisaged. It is also planned to issue two Open Calls for the experimental facility to be used by researchers from outside the project and involvement of various types of users to develop new applications.Such a unique facility with practical experience gained and feedbacks received, enables better understanding and insight into issues of: 1) Required capacity, 2) Scalability, 3) Interoperability 4) Stimulation of faster development of new and innovative applications and 5) Influence specification of FI architecture design.The SmartSantander project will enable the Future Internet of Things to become a reality.
