Those that can use wireless mobile networks to access the Internet are some mobile phones with Internet access capabilities, laptops with built-in wireless network cards, and some tablet computers with Internet access capabilities; the wireless access point is a separate device that can be connected through a wired network Routers can also be integrated with routers to enable devices to connect wireless networks to wired networks.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
Things that can use wireless mobile networks are laptops with built-in wireless network cards, some mobile phones with Internet access capabilities, and some mobile phones with Internet access capabilities. Tablets can use wireless mobile devices to access the Internet.
Tablet computer, also called Tablet Personal Computer (Tablet PC), is a small, portable personal computer with a touch screen as the basic input device. It has a touch screen (also known as tablet technology) that allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can enter via built-in handwriting recognition, an on-screen soft keyboard, speech recognition, or a real keyboard (if the model is equipped).
Wireless Access Point (English: WirelessAccess Point, referred to as: Wireless AP) is a device in the computer network that connects the wireless network to the wired network (Ethernet), and Called a wireless base station. It usually comes as a separate device and is connected to the router through a wired network, but it can also be integrated with the router. A wireless access point is different from a hotspot, which is a physical location that can connect to a wireless LAN. Roaming is the operation of several wireless access points, connecting the data sent from one access point to another access point to expand the wireless network; conversely, if there is no access point, the entire wireless network will become a point-to-point ad-hoc networks. The wireless access point also has the function of dynamically configuring IP addresses through DHCP.
Wireless APs are mostly used in large companies. Large companies need a large number of wireless access nodes to achieve large-area network coverage. At the same time, all access terminals belong to the same network, which also facilitates company network administrators to simply Implement network control and management.
Wireless routers are generally used in home and SOHO environment networks. In this case, the coverage area and users are generally small, and only one wireless AP is enough. A wireless router can access the ADSL network and convert it into a wireless signal at the same time. Compared with buying a router and a wireless AP, a wireless router is a more affordable and convenient choice.
Extended knowledge: Wireless mobile communication
Wireless communication is divided into two categories: wireless mobile communication (will be introduced below) and wireless local area network (LAN) communication (Introduced in "Wireless LAN Communication"). Their transmission facilities are fundamentally different. Wireless LAN communications use transmitters and receivers that are placed wherever a company wants them and are owned by that company. Wireless mobile communications require telephone bureaus or other public services to provide facilities for users "out of the office" or "on the go" using packet radio, cellular networks and satellite stations to transmit and receive signals.
