Fixed wireless terminal refers to the wireless local loop application.When a wireless terminal enters the signal coverage area of a wireless LAN, the access point in the area must first authenticate the wireless terminal and check the identity information provided by it to prevent illegal user access. After that, the AP is associated with the wireless terminal, through which the AP accepts the wireless terminal and uses it as a wireless node of the wireless LAN to communicate with it. Wireless terminals rely on wireless communication technology for data transmission and signal reception. These technologies include cellular mobile communication technology, Wi-Fi technology, Bluetooth technology and so on. These technologies enable wireless terminals to communicate and transmit data without connecting any cables, providing users with great convenience and flexibility. Individual users can use wireless terminals to access the Internet anytime, anywhere, to obtain information, communication, entertainment, etc. At the same time, wireless terminals are also widely used in the enterprise field, such as the Internet of Things applications, a variety of intelligent devices through wireless communication technology data interaction, improve production efficiency and management efficiency. In addition, in the field of smart home, wireless terminals also play an important role in bringing users a more intelligent and convenient life experience.
