Descripció del contingut i pla d'activitats:
Aquest treball de final de grau, té com a objectiu, l'anàlisi de les comunicacions sens fils en les bandes de 2,4 GHz i 5 GHz dins de la fàbrica de SEAT a Martorell.

Es desenvoluparà tant a les zones interiors de tallers, orientant-se a la comunicació de dispositius electrònics enfocats especialment a IoT, tenint en compte també dispositius mòbils; com a espais exteriors de la planta, on s'avaluarà la cobertura de la xarxa Wi-Fi.

L'anàlisi consistirà en el reconeixement de la cobertura de la zona, així com la qualitat del senyal capturat, aconseguint d'aquesta manera, la identificació de punts febles de les instal·lacions per tal de proposar millores i esclarir les raons d'aquests punts febles.

Per dur a terme el treball, es planteja la utilització d'eines com Acrylic Wi-Fi Heatmap o, NetSpot, les quals permeten generar mapes de calor que poden ser de gran utilitat per la realització de l'estudi.
 
Overview (resum en anglès):
Given the unceasing increase of smart and connected devices in industrial environments and considering the high scalability and reconfiguration flexibility enabled by wireless networks in a dynamic infrastructure, it has been decided to analyze the current state of the Wi-Fi communications at SEAT Martorell factory. The aim is to verify if the current conditions are optimal for minimizing operational errors and ensuring communication between devices that use Wi-Fi frequency bands, and whether this existing operative scenario allows an appropriate adaptation to the current and future wireless evolutions or if, on the contrary, substantial changes are required.

To fulfill this goal, the situation of both production and office networks is analyzed across several of the workshops from the industrial plant. The structure followed includes, firstly, predictive studies using the company's software, from which preliminary data regarding signal quality is shown for registered access points, along with channel utilization and noise information. Secondly, data measurements are carried out on-site by walk-through surveys using a Wi-Fi networks analysis program, obtaining SNR and RSSI heat maps, among others. Finally, on the one hand, short, medium and long-term improvement measures are proposed for the factory in general; on the other hand, specified topology reconfigurations are proposed in the different evaluated locations.

Based on the captured and processed data, it is concluded that the present circumstances of the factory heavily limit any upgrade in Wi-Fi technologies, since the majority of terminal devices and infrastructure components are not compatible with standards such as Wi-Fi 6, 6E or 7. Although the observed coverage and signal quality are generally sufficient for the present-day functionalities, this fact does not remove the necessity to ensure a more consistent performance margin across the workshops in order to overcome sudden disabling levels of noise that could limit satisfactory communication; furthermore, it does not eliminate the need to plan the restructuring of multiple infrastructure elements of the factory to enable the capacity to face future applications and requirements.

Overall, the results highlight the importance of a strategic and forward-looking approach as a key factor in enabling reliability and readiness for future technological use cases.
