3e–525C–2 Wireless Access Point Glossary Glossary 802.11 802.11 refers to a family of specifications developed by the IEEE for wireless LAN technol- ogy. 802.11 specifies an over-the-air interface between a wireless client and a base station or between two wireless clients. The IEEE accepted the specification in 1997. 802.11b (also referred to as 802.11 High Rate or WiFi) 802.11b is an extension to 802.11 that applies to wireless LANs and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. - Page 80 3e–525C–2 Wireless Access Point Glossary SNMP Simple Network Management Protocol SSID A Network ID unique to a network. Only clients and access points that share the same SSID are able to communicate with each other. This string is case-sensitive.
