What is 802.11(a,b,g,n,ac)?

IEEE 802.11 is a set of media access handle (MAC) and physical layer (PHY) specifications for implementing wireless regional location network (WLAN) pc communication in the 2.four, 3.six, 5 and 60 GHz frequency bands. They are designed and maintained by the IEEE LAN/MAN Requirements Committee (IEEE 802). The base version of the normal was released in 1997 and has had subsequent amendments. The normal and amendments offer the basis for wireless network goods using the Wi-Fi brand. Although each amendment is officially revoked when it is incorporated in the latest version of the regular, the corporate planet tends to marketplace to the revisions simply because they concisely denote capabilities of their goods. As a result, in the marketplace location, each and every revision tends to grow to be its own normal.

802.11 and 802.11x refers to a loved ones of specifications developed by the IEEE for wireless LAN (WLAN) technologies. 802.11 specifies an more than-the-air interface between a wireless client and a base station or among two wireless clients. The IEEE accepted the specification in 1997.

802.11n, which once Apple confusingly dubbed “AirPort Extreme” — the same name the company gave to the earlier 802.11g specification — is a wireless networking common 1st supported by the original Apple Television. Starting on July 20, 2011, Apple quietly began refering to this regular just as 802.11n “Wi-Fi” for simplicity.

Apple also supports 802.11n on Macs beginning with the Core two Duo-based models (some very first require enabler software program to be installed) — with the exception of the iMac “Core 2 Duo” 1.83 17-Inch (IG). For a total list of G3 and Later Macs that support the distinct standards of AirPort, please refer to the “By Capability” section of EveryMac.com.

These are various types of Wi-Fi (or AirPort) technologies. IEEE 802.11, to give the technology its technical title, is a set of wireless specifications designed by the Institute of Electrical and Electronics Engineers. They produce a set of wireless specifications and businesses like Apple stick to them to make certain that devices (such as the iPhone) can talk to other devices (such as Net Routers).

The various diverse flavours of 802.11 Wi-Fi have distinct speeds, power requirements and so on. 802.11ac is the most recent to be ratified and delivers an estimated multi-station WLAN throughput of upwards of 1 gigabit per second 802.11ac is covered by Apple’s most current AirPort Intense wireless router.
