Description: A Wi-Fi connectivity network is a system that allows wireless connection between different devices and systems, facilitating communication and data exchange without the need for physical cables. This technology uses radio waves to transmit information, enabling devices to connect to the Internet and to each other efficiently and conveniently. Wi-Fi networks are essential in home, business, and public environments, providing flexible and mobile access to the network. Wi-Fi standards, such as 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac, have evolved over time, improving speed, range, and security of connections. The ease of use and the ability to connect multiple devices simultaneously make Wi-Fi networks an integral part of modern life, allowing a wide range of activities from online browsing to multimedia streaming and real-time communication.
History: Wi-Fi technology originated in the 1990s when the IEEE 802.11 standard was developed in 1997. This first standard allowed speeds of up to 2 Mbps. Over the years, several improvements and new standards have been introduced, such as 802.11b in 1999, which increased speed to 11 Mbps, and 802.11g in 2003, which reached up to 54 Mbps. The arrival of 802.11n in 2009 marked a significant milestone, offering speeds of up to 600 Mbps and significantly improving range. In 2013, the 802.11ac standard introduced even faster speeds and advanced capabilities, becoming the predominant standard in modern Wi-Fi networks.
Uses: Wi-Fi networks are used in a wide variety of applications, from Internet access in homes and offices to connecting devices in public environments such as cafes and airports. They enable data transmission between devices such as smartphones, tablets, laptops, and smart home devices. Additionally, they are fundamental for the implementation of technologies like the Internet of Things (IoT), where multiple devices communicate with each other over the network.
Examples: Examples of Wi-Fi network usage include connecting a smartphone to a router for Internet access, streaming video from a laptop to a smart TV, and connecting smart home devices like thermostats and security cameras to a home network for remote control. They are also used in businesses to allow employees to work flexibly from different locations within the office.
