This final degree thesis is an analysis of the IEEE 802.11ax standard and the two subsequent certifications, Wi-Fi 6 and Wi-Fi 6E, with the aim of obtaining information to understand these new IEEE 802.11 standards. We will start by presenting the evolution of the IEEE 802.11 standard throughout its history, detailing the main and most important features such as frequencies, bandwidths, and maximum transmission rates. Then, we will discuss the IEEE 802.11ax specification, distinguishing the mechanisms defined at the physical layer (PHY) and the medium access control layer (MAC). Afterwards, we will proceed with the performance analysis, starting with the description of the scenarios, where we will explain the specifications of the elements used (access points, and adapters) to work in this new frequency band and the dispositions of each of the scenarios. Also, with the help of a spectrum analyser, a visualization of the spectrum found in the 3 bands will be made, which will help us to see how congested they are. The analysis will consist of tests carried out in a laboratory to measure, mainly, the maximum throughput, outdoor tests to measure throughput as a function of distance and, finally, an analysis of the association time will be carried out for the different frequency bands.
