Wi-fi can be said to be the most widely applied wireless network transmission technology at this stage, which is supported by almost all network equipment, such as mobile phones, tablet computers, etc. Wi-fi technology can simply be understood as having a wire network signal converted to a wireless network signal that allows equipment to be interconnected through wireless signals, with the greatest advantage that it does not need to be connected by cable, and that it has low launch power and is highly suitable for both office and household environments。
As wi-fi is a technology included in wlan, it can be said that wlan applications are very extensive, ranging from home to business to urban networks. The home wireless wlan can be seen as the simplest application, with equipment to access internet resources through wireless hotspots generated by routers. Enterprises are also allowed to form a cross-construction wlan network through bridges in multiple buildings。
Wlan can use a combination of two or more of the components to form multilayered, wireless and wired computer networks. Wi-fi actually provides a means of interconnecting various terminals with wireless connections, while shielding users from differences in equipment。
In our practical applications, the way to connect and use wlan is particularly simple. In the case of family wlan, we simply need to be equipped with wireless access, usually by wireless routers, a device with wireless functionality such as a mobile phone, a laptop, etc., and if we use wireless devices such as desktops, we need to connect with a wireless card. You can access the connection by entering a password。
