What are the two network structures of WLAN?

Decentralized topology (peer-to-peer network) and centralized topology (structured network).

The basic structure of WLAN can be divided into two types: non-central topology and central topology. Non-central topology is also called no infrastructure.

Wireless LAN with central topology is also called wireless LAN with infrastructure.

Extended data:

1. In a topology without a center, any two wireless stations can communicate directly. Main characteristics of wireless local area network without central topology structure

Features: no wiring, easy network construction and good stability, but limited capacity, only suitable for interconnection communication between single user stations, not

Can be used to develop public wireless access services.

2. There is a central topology that requires a wireless access point (also called wireless AP or wireless hub) as the center.

This station is used to receive, cache and forward data between wireless workstations and wired networks, and the access of other stations to the network is provided by the central station.

To control. Each site only needs to be within the coverage of the central station (usually it can cover dozens to hundreds of users with a coverage radius of several hundred).

Meter) can communicate with other sites. The disadvantage of this structure is that the overall performance of the network depends on the central node.
