What are the two networking modes of WLAN? What are their characteristics?

There are two networking modes for WLAN: point-to-point mode (point-to-point wireless network) and infrastructure mode (centralized control network).

1, point-to-point mode (point-to-point wireless network)

Peer-to-peer wireless network is a kind of peer-to-peer mobile network. Without the support of wired infrastructure, all nodes in the network are composed of mobile hosts. There is no wireless AP (wireless access point) in the network, and communication is realized through free networking of multiple wireless network cards.

2. Infrastructure mode (centralized control network)

Centralized control mode network is an application mode integrating wired and wireless LAN architecture. In this mode, the wireless network card is wirelessly connected to the wireless AP, and then connected to the wired network through the wireless AP. In fact, the infrastructure mode network can also be divided into two modes: one is the mode of wireless router+wireless network card to establish connection; One is the mode of wireless AP+ wireless network card establishing connection.

There are many WLAN implementation protocols, among which Wi-Fi, the most famous and widely used technology, actually provides a technology that can wirelessly interconnect various terminals, shielding the differences between various terminals for users. ?

In practical application, the access mode of WLAN is very simple. Take home WLAN as an example, you only need a wireless access device-router, a computer or terminal with wireless function (mobile phone or PAD), and a computer without wireless function only needs to plug in a wireless network card.

With the above equipment, the specific operation is as follows: use a router to connect hotspots (other wireless networks that have been set up and are within the receiving range) or wired networks to the home, and configure the routing according to the instructions provided by the network service provider.

After the configuration is completed, put the receiving terminal in the coverage area of the home (the stable coverage area of WLAN is about 20 m~50 m), turn on the wireless function of the terminal, and enter the user name and password given by the service provider to access the WLAN.
