Descripció del contingut i pla d'activitats:
L'especificació IEEE 802.11ax, amb les dues certificacions Wi-Fi (Wi-Fi 6 i Wi-Fi 6E), consisteix en la darrera generació Wi-Fi present als dispositius d'electrònica de consum. Wi-Fi 6E ha obert el funcionament d'aquesta tecnologia a la nova banda de 6GHz, permetent l'operació en una banda menys congestionada i proporcionant un ample de banda més extens. Aquest projecte té com a objectius, per una banda,
aprofundir en l'avaluació de l'especificació Wi-Fi 6E i els reptes de la seva operació a la banda de 6GHz. En segon lloc, el projecte pretén portar la tecnologia Wi-Fi 6/6E a l'entorn dels vehicles aeris no tripulats (drones), analitzant la seva viabilitat com a interfície de comunicacions en aquest àmbit.
 
Overview (resum en anglès):
This study examines the viability of the new IEEE 802.11ax amendment, certified as Wi-Fi 6/6E, as a wireless communication interface.

To achieve this objective, key parameters of this technology are evaluated, such as maximum throughput, scan time, and handover time, through tests with commercial Wi-Fi 6/6E devices. Additionally, the most congested frequency bands and channels are examined, particularly within the 6 GHz band, in order to minimize interference in the link between the drone and the ground control. Finally, the coverage that this technology provides in missions conducted at the DroneLab of the Parque Mediterráneo de la Tecnología is analyzed.

These goals are organized into seven chapters. The first chapter provides an overview of the IEEE 802.11 standard, reviewing its history, key concepts, and amendments to date. The second chapter focuses on drones, their flight principles, and how Wi-Fi 6/6E can enhance their operations. The following chapters encompass the experimental part, including throughput, scanning, and transfer tests in the laboratory, as well as studies on Wi-Fi network distribution in three Spanish cities. Finally, at the DroneLab, a 3D Wi-Fi coverage map is created, studying its behavior in each band. The work concludes with recommendations for future research and an analysis of the sustainability of this technology.

The results show high throughput values, reaching up to 2 Gbps. Significant improvements in scan and transfer times are also observed; however, they are not sufficient for certain drone use cases. Nevertheless, the Wi-Fi 6/6E certification is not yet widely adopted, as its presence in cities is only 0.1\%. Regarding coverage, the three analyzed bands are capable of supporting applications such as video streaming at most points in the DroneLab. However, the 6 GHz band presents certain limitations at the edges of this volume.

In summary, considering the limitations and leveraging the advantages, this technology could represent a significant advancement in the field of drones, improving the performance of their wireless communications.
