WLAN is the abbreviation for Wireless Local Area Networks, which is a wireless local area network. wLAN utilizes radio frequency (Radio Frequency; RF) technology, which uses electromagnetic waves to replace the old-fashioned obstruction of twisted copper wires (Coaxial) to form a local area network, and make communication connections in the air, making it possible to use a simple access architecture to allow users to achieve the ideal of "information on the go, convenient to go everywhere". WLANs can utilize a simple access architecture to allow users to achieve the ideal world of "information on the go, convenience on the go" through it.

m~50 m) to place the receiving terminal, turn on the wireless function of the terminal, enter the wireless function given by the service provider, and then enter the wireless function of the terminal, and then turn on the wireless function of the terminal.
