1. Basic concepts

In a broad sense, wireless local area network WLAN (Wireless Local Area Network) refers to a network that uses radio waves, laser, infrared, etc., to replace some or all of the transmission media in the wired LAN.

WLAN technology is based on the 802.11 standard series, that is, wireless Lans that use high-frequency signals (such as 2.4GHz or 5GHz) as transmission media

The basic concepts of Huawei's WLAN business:

Workstation STA (Station): an end device that supports the 802.11 standard. For example, computers with wireless network cards, mobile phones that support WLAN, etc.

Wireless controller AC (Access Controller): in the centralized network architecture, AC controls and manages all AP in the wireless local area network. For example, AC can provide authentication services to WLAN users by exchanging information with the authentication server

Access point AP (Access Point): provides wireless access services based on 802.11 standard for STA, which acts as a bridge between wired and wireless networks.

Thin access point FIT AP (FIT Access Point): provides STA wireless access services in the thin access point (FIT AP) architecture of a centralized network architecture, which is different from the traditional FAT AP and only provides reliable, high-performance wireless connectivity. Other enhancements are centrally configured on the AC.

Central AP (Central Access Point): in the agile distributed Wi-Fi solution architecture of centralized network architecture, the central AP agent AC shares the centralized management and collaboration functions of RU, such as STA online, configuration distribution, and STA roaming between RU.

Remote unit RU (Remote unit): in the agile distributed Wi-Fi solution architecture of centralized network architecture, the remote unit, as the remote RF module of the central AP, is responsible for the sending and receiving of air port 802.11 messages.

Wireless access Point Control and Specification CAPWAP (Control And Provisioning of Wireless Access Points): a general encapsulation and transport mechanism defined by the RFC5415 protocol for interworking between AP and AC

Radio frequency signal: provides the transmission medium based on the 802.11 standard WLAN technology, is a high-frequency electromagnetic wave with long-distance transmission capability. The radio frequency signal referred to in this paper is the electromagnetic wave in the 2.4G or 5G frequency band.

Virtual access point VAP (Virtual Access Point): a virtual business function entity on an AP device. Users can create different VAP on an AP to provide wireless access services for different user groups.

Service set identifier SSID (Service Set Identifier): represents the identity of a wireless network and is used to distinguish between different wireless networks. For example, when we search for an accessible wireless network on a laptop, the network name displayed is SSID
