-Mobility Services, network management, network unification, access points, and clients device are component included in the cisco unified wireless network
-Wireless network use CSMA/CA protocol to Avoid collision on the network
-IEEE 802.11 is the standard that defines wireless LANs
-A 20% overlap is recommend by adjacent wireless cells
-Service set identifier (SSID) is a name that identifies a particular 802.11 wireless LAN,
-The basic service set (BSS) is the basic building block of an 802.11 wireless LAN. In infrastructure mode, a single access point (AP) together with all associated stations (STAs) is called a BSS.
-An independent basic service set (IBSS) is ad-hoc network of client devices without a controlling access point. in which case the SSID is chosen by the client device that starts the network, and broadcasting of the SSID is performed in a pseudo-random order by all devices that are members of the network.
-An extended service set (ESS) is a set of one or more interconnected BSSs and integrated local area networks that appear as a single BSS to the logical link control layer at any station associated with one of those BSSs
