Broadband connections are becoming an essential service of any home. To be connected at more than 100Mbps, to 1Gbps, or to 10Gbps, is more an economical problem, rather than a technological one. The dissertation purpose is to proof that users are the key piece of the fiber access networks – especially of Fiber to the Home – by developing a techno-economic sharing access network scenario model. Currently, the network is dominated by Top-down deployments made by telecom operators that still see in the user the consumer of their services. However, this dissertation implements a Bottom-up approach, and the user becomes a stakeholder of the access network. Moreover, he turns into one investor of the fiber work, and gets more benefits by adding more users, thus deriving into a community-shared network model. The role of State, Municipalities, and private operators are analyzed as possible factors that may help or hinder those user initiatives.
