802.11 (sometimes rename 802.11x, but not 802.11X) is the generic identification of a family of stas well asards for wirenot increase netjob associated to Wi-Fi.
The numbering scheme for 802.11 comes from the Institute of Electrical as well as Electronics Engineers (IEEE), who applications "802" similar the identification of a committee for netjob stas well asards that becomposedofs Ethernet (IEEE 802.3). "11" refers to the wirenot increase native area netoperations (WLANs) job group inside their 802 committee.
IEEE 802.11 stas well asards tellthedifference detailed rules for WLAN communication. The optimum kpresentn of these stas well asards becomposedof 802.11g, 802.11n as well as 802.11ac.
The First 802.11 Stas well asard
802.11 (with no letter suffix) wsimilar the original stas well asard in this family, ratified in 1997. 802.11 setuped wirenot increase native netoperation communication similar a primestream revisenative to Ethernet. Being early production technology, 802.11 had serious ceilingations that holdbacked it from appearing in companies products – information rates, for example, 1-2 Mbps. 802.11 wsimilar rapid pickupd on as well as made obsolete within two years depend on both 802.11a as well as 802.11b.
Evolution of 802.11
Each novel stas well asard within the 802.11 family (often rename "amendments") receipts a identification with novel letters appended.. After 802.11a as well as 802.11b, novel stas well asards were bethecaused, successive productions of the primary Wi-Fi protocols rolled out in this order:
802.11g (ratified in 2003)802.11n (ratified in 2009)802.11ac (ratified in 2013)
In contrast with these most common updates, the IEEE 802.11 job group befoundedoned the number of other associated protocols as well as other alters. The IEEE allinall similarsigns identifications in the order job groups are kicked off more important questions the stas well asard is completed. For example:
802.11c – operation of bridge links (moved to 802.1D)802.11d – global compliance with regulations for application of wirenot increase signal spectrum (2001)802.11e – Quality of Service (QoS) insupportof (2005-2007)802.11F – Inter-Access Point Protocol recommendation for communication between entryway points to insupportof roaming clients (2003)802.11h – enhanced version of 802.11a to insupportof European regulatory needments (2003)802.11i – security pickupments for the 802.11 family (2004)802.11j – enhancements to 5 GHz signaling to insupportof Japan regulatory needments (2004)802.11k – WLAN system managementment802.11l – skipped to avoid confusion with 802.11i802.11m – primetenance of 802.11 family evidence802.11o – skipped802.11p – Wirenot increase Access for the Vehicular Environment802.11q – skipped802.11r – fsimilart roaming insupportof via Bsimilaric Service Set transitions802.11s – ESS mesh netjob for entryway points 802.11T – Wirenot increase Perappearsance Prediction – recommendation for testing stas well asards as well as metrics802.11u – internetjob with 3G / cellular as well as other appearss of external netoperations802.11v – wirenot increase netoperation managementment / device configuration802.11w – Protected Man social backgroundment Frames security enhancement802.11x – skipped (generic identification for the 802.11 family)802.11y – Contention Bsimilared Protocol for disruptnce avoidance
The Official IEEE 802.11 Working Group Project Timelines p social background is published depend on IEEE to reveal the status of each wirenot increase stas well asard recently under befoundedonment.
