This project is about smart technologies that have been developing for the last years and their implementation in the airport field. The report is divided into two parts: the first part deals with a theoretical study, whereas the second one is about the practical application of the previous analysis. In the first place, the concepts of smart technology and smart airport are defined as well as every aspect that this implementation, in a certain area, involves. Next, some examples of the considered as the best airports in the world are shown. This list is based on either the technologies development or the passengers' point of view. Also, the fields in which these technologies are mainly implemented are exposed. As it is shown along the report, the use of these technologies improves and eases the experience of both passengers and workers. But the fact that they are new means that the security to protect them from intruders' attacks is still being developed. This is the reason why the possible attacks that could happen to communication network are analysed, too. The airport chosen for the second part of the project is the Taipei Songshan Airport, Taiwan. First of all, the actual existing technologies in this airport are analysed and it is studied if this airport could be considered smart or not. Therefore, a visit to the airport will be necessary. Secondly, a new application of smart technology is thought and developed at the mentioned airport. The proposal application is a sensor network deployed along the terminal able to locate luggage carriers. After this, the network is designed and finally the approximate budget needed to invest is calculated.
