Trabalho de Projeto apresentado à Escola Superior de Artes Aplicadas do Instituto Politécnico de Castelo Branco para cumprimento dos requisitos necessários à obtenção do grau de Licenciado em Design, Comunicação e Produção Audiovisual
The project developed aims to respond to the communication needs of a Portuguese agri-foods company called MEPS. The project emerges as a profitable opportunity for both parties (student and company) as the communication sector is often sidelined by small and medium-sized companies, due to the high cost that a communication department requires, and in this way (degree project) they do not need to invest, and the student has the chance to experience a more professional exercise. MEPS, despite being a company founded around 1920, did not present a communication that appealed to a defined public, it did not have a coherent visual identity and its digital media are out of step with current technology, so it was necessary, through a methodology, to create a new, coherent way of communicating that unifies the means of communication. It was necessary to make an analysis of the brand's competitors, from more direct competitors to inspirational cases, as well as the analysis of the current brand itself, in order to determine which aspects of communication to change, to maintain, which are the strengths, weaknesses, threats and opportunities to explore, thus helping to define the brand's concept and positioning. Having the positioning well defined, it was possible to develop some sketches of the graphic brand. These sketches would later be improved to arrive at a better graphic branding option, which in turn would be tested in terms of visibility. With the selected graphic brand, the remaining elements of the visual identity were also selected, such as textures, colours, shapes, fonts, 5th element, imagery, and graphics, organized in the form of a stylescape. After defining the visual identity, the brand book was developed as a way to standardize the applications that followed, such as product packaging, website mockup, merchandising, product´s catalog, uniforms, car fleet and stationery. It was also necessary to develop the final arts for the printing of the applications, and respective costs, which together with the labour costs, totalled the project´s price, if it was paid and applied

This paper describes the implementation and the technical specifications of a geolocation database assisted by a spectrum-monitoring outdoor network. The geolocation database is populated according to Electronic Communications Committee (ECC) report 186 methodology. The application programming interface (API) between the sensor network and the geolocation database implements an effective and secure connection to successfully gather sensing data and sends it to the geolocation database for post-processing. On the other hand, the testbed allows authorized TV white space devices to gain access to the services of the geolocation database, according to a draft implementation of Internet Engineering Task Force (IETF) Protocol to Access White Space (PAWS) Two experimental methodologies are available with the testbed: one focused on coexistence studies with commercial wireless microphones, when the testbed is used for sensing only, and another for demonstration purposes, when the testbed is also used to emulate wireless microphone signals. Overall, this hybrid approach is a promising solution for the effective use of TV white spaces and for the coexistence with digital TV broadcast signals, or dynamic incumbent systems, such as unregistered wireless microphones.

This chapter describes outdoor transmission tests and field measurements in TV white spaces (TVWS) carried out in Europe. TVWS Measurements in Germany showed that the extended Hata model is appropriate to describe the path loss over distances up to a few kilometers. During the TVWS trial in Slovenia, we combine infrastructure sensing with geo-location database access to protect not only DVB-T, but also wireless microphone (WM) signals from TVWS devices interference.
