Concepts

Concepts

  • Station (STA): a terminal that supports 802.11 standards. For example, a PC that has a wireless network interface card (NIC) or a mobile phone that supports WLAN.

  • Access point (AP): a device that provides 802.11-compliant wireless access for STAs. APs connect wired networks to wireless networks.

    • Fat AP: an AP that provides wireless access for STAs in the autonomous architecture. A Fat AP provides wireless connection, security, and management functions.
  • Radio signal: a high-frequency electromagnetic wave that has long-distance transmission capabilities. Radio signals provide transmission media for 802.11-compliant WLANs. Radio signals described in this document are electromagnetic waves in the 2.4 GHz or 5 GHz frequency band.

  • Virtual access point (VAP): a WLAN service entity on an AP. You can create different VAPs on an AP to provide wireless access service for different user groups.
  • Service set identifier (SSID): a unique identifier that identifies a wireless network. When you search for available wireless networks on your laptop, SSIDs are displayed to identify the available wireless networks.

    SSIDs are classified into two types:
    • Basic service set identifier (BSSID): the link-layer MAC address of a VAP on an AP. Figure 9-1 shows the relationship between VAP and BSSID.
      Figure 9-1  Relationship between VAP and BSSID
    • Extended service set identifier (ESSID): a chosen identifier for one or a group of wireless networks. For example, in Figure 9-1, SSID guest identifies one wireless network, and SSID internal identifies another wireless network. A STA scans all wireless networks and selects a wireless network based on the SSID. In general terms, an SSID refers to an ESSID.
  • Basic service set (BSS): an area covered by an AP. STAs in a BSS can communicate with each other.
