Description: A WLAN card, or wireless network card, is a hardware component that allows a computer to connect to a wireless network. This device integrates into the system to facilitate communication without the need for cables, using technologies like Wi-Fi. WLAN cards can be internal, installed directly on the motherboard, or external, connected via USB ports. Their primary function is to receive and send data through radio waves, enabling users to access the Internet and local networks conveniently and flexibly. WLAN cards are essential today, as wireless connectivity has become a standard in most environments, from homes to offices and public spaces. Additionally, these cards often include features such as support for different Wi-Fi standards (like 802.11n, 802.11ac, and 802.11ax), as well as security capabilities to protect transmitted information. In summary, the WLAN card is a key element in modern network infrastructure, enabling mobility and connectivity in an increasingly digital world.
History: Wireless networking technology began to develop in the 1970s, but it was in 1997 that the 802.11 standard was established, allowing for the creation of the first commercial WLAN cards. Over the years, standards have evolved, improving the speed and security of wireless connections. In 1999, the 802.11b standard was introduced, popularizing the use of Wi-Fi in home and commercial environments. Since then, more advanced versions have been released, such as 802.11g, 802.11n, 802.11ac, and 802.11ax, each offering significant improvements in performance and capacity.
Uses: WLAN cards are primarily used to connect devices to wireless networks, allowing access to the Internet and communication between devices on a local network. They are common in laptops, desktops, tablets, and other mobile devices. Additionally, they are used in various environments to facilitate connectivity in offices and collaborative workspaces, as well as in homes to provide Internet access to multiple devices without the need for cables.
Examples: Examples of WLAN cards include the TP-Link Archer T6E, which supports the 802.11ac standard and offers speeds of up to 1300 Mbps, and the Intel Dual Band Wireless-AC 7260, which is popular in laptops and provides high-speed connectivity with low power consumption.
