SSID employee: SSID hiding is enabled for this SSID, and only users who know the SSID can join the network employee after being authenticated.That is, a WLAN can be divided into many subnets with different SSIDs, and each subnet provides customized services for its user group.įor example, an enterprise network is divided into two subnets for employees and guests:

Each VAP targets at a specified user group, and has a unique SSID as well as customized configurations of security policies, access authentication, rate limiting, access control, multi-user multiple-input multiple-output ( MU-MIMO), and orthogonal frequency division multiple access ( OFDMA). With this function, multiple VAPs can be created on an AP. With the growth of WLAN users, a single network cannot meet the requirements of users with different identities.Ĭurrently, APs support the multi-SSID function. BSSID is not perceived by users, and is used for managing and maintaining wireless networks, and locating problems.ĭividing a Network into Subnets Based on Multiple SSIDsĮarly 802.11 chips in APs support only a single SSID, providing only one WLAN for users. Generally, the so-called SSID refers to an ESSID, which is a wireless network name in the SSID list.

SSID is classified into BSSID and ESSID, which identify the basic service set (BSS) and extended service set (ESS), respectively. For example, in an enterprise network, the administrator can configure the SSID employee for employees and the SSID guest for guests to provide different services for enterprise employees and guests. This distinguishes between access permissions and network functions of different users and enhances the WLAN flexibility and security.

The administrator can divide a WLAN into subnets with different SSIDs and configurations to allow users of different identities to access corresponding networks based on the SSIDs.

The same SSID can be configured for different APs in a WLAN to implement the roaming function, which enables users to move freely in the area covered by these APs without interrupting network services.In the SSID list, an easy-to-understand SSID helps users to easily find the wireless network to access.Appropriate SSIDs will improve the Internet access experience for terminal users:.
