Description: Wi-Fi access systems are methods and technologies used to connect devices to a wireless network. These systems allow devices such as smartphones, laptops, tablets, and other equipment to connect to the Internet or local networks without the need for cables. They use radio waves to transmit data, providing flexibility and mobility to users. Wi-Fi access systems are based on standards established by the IEEE, with the most common being 802.11, which has evolved over the years to offer higher speeds and better coverage. Additionally, these systems may include security features such as WPA2 and WPA3, which protect the information transmitted over the network. The implementation of Wi-Fi access systems is essential in home, commercial, and public environments, facilitating connectivity in a variety of situations. Their ability to support multiple devices simultaneously and their ease of use have made them a preferred solution for Internet access today.
History: The development of Wi-Fi access systems began in the 1990s when the IEEE established the 802.11 standard in 1997. This first standard allowed speeds of up to 2 Mbps. Over the years, several improvements have been introduced, such as 802.11b in 1999, which increased the speed to 11 Mbps, and 802.11g in 2003, which reached up to 54 Mbps. In 2009, the 802.11n standard was released, offering even higher speeds and better coverage. More recently, 802.11ac and 802.11ax (Wi-Fi 5 and Wi-Fi 6, respectively) have taken the technology to new heights, allowing gigabit speeds and better handling of multiple devices.
Uses: Wi-Fi access systems are used in a wide variety of applications, from home networks to business and public environments. At home, they allow devices such as computers, smartphones, and smart devices to connect to the Internet. In businesses, they facilitate communication and access to shared resources without the need for cables, improving employee flexibility and mobility. In public places, such as cafes and airports, Wi-Fi access systems provide connectivity to customers, enhancing the user experience.
Examples: Examples of Wi-Fi access systems include home routers that allow multiple devices to connect to a local network, access points in offices that extend network coverage, and public Wi-Fi networks in places like libraries and shopping centers that offer free Internet access. Additionally, technologies like Wi-Fi Mesh allow for broader and more uniform coverage in large areas, enhancing the user experience.
