Page 8: Terminology Used In This Guide
Terminology Used in This Guide Ad-hoc Network An ad-hoc network is a wireless local-area network (WLAN) made up of stations communicating directly with each other through their wireless interfaces. There is no central relay point, and normally no connection to a wired network. Ad-hoc mode is sometimes referred to as peer-to-peer, computer-to-computer, or Independent Basic Service Set (IBSS) mode. -

BSSID, MAC Address A Basic Service Set (BSS) is two or more wireless devices that are in communication with each other. Like every wired Ethernet device, every wireless device has a fixed, unique “media access control” (MAC) address. When wireless devices establish communication, they automatically select the MAC address of one BSS member as an identifier for the group;... -

Roaming When APs covering adjacent areas have the same SSID and encryption settings, a mobile device that also shares those settings can communicate through the APs continuously while moving from one coverage area to another. This is known as roaming. When one AP’s signal begins to weaken, the mobile device automatically searches for another AP that it is authorized to “associate with”... -
