O estudo da evolução tecnológica das redes sem fio WiFi até a geração 7

Abstract

With the evolution of the Internet, access to information is fundamental and must be available everywhere, including remote neighborhoods and regions. Therefore, it is essential that companies, schools, universities, industries, and especially the government invest in technology to improve communication and access to information, both in urban and rural areas, by providing internet services. To provide internet service in rural and remote areas several technologies are at hand such as: satellite, for example, with Starlink, microwave, optical fiber, coaxial cable, PLC (Power Line Communication), WiMax, and WiFi. One of the main notorious differentials from one company to another is how much it invests and knows how to use new technologies and innovations in software and hardware. Therefore, universities must be at the forefront in including new technologies so that students and future professionals can learn and present the technologies to society. That said, for the perfect operation of a company, it is necessary to use a network to interconnect workstations, peripherals, terminals, cell phones, iPads, and other devices. This article presents the evolution of wireless networks and a study of the art of WiFi technology, up to the most recent WiFi 7, which does not yet exist commercially but is projected, according to Qualcomm, the world's largest supplier of WiFi peer processors, to be available on the market in the second half of 2024. Given this scenario we see the importance of strengthening the knowledge about the evolution of technologies in this area and understand the improvements from one model to another.
