An extension to 802.11 specification developed by the IEEE for wireless LAN (WLAN) technology. 802.11n builds upon previous 802.11 standards by adding multiple-input multiple-output (MIMO). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding. The speed is 100 Mbit/s (even 250 Mbit/s in PHY level), and so up to 4-5 times faster than 802.11g. 802.11n also offers a better operating distance than current networks.
See 802.11 for a complete overview of the 802.11x family of specifications.
An extension to 802.11 specification developed by the IEEE for wireless LAN (WLAN) technology. 802.11r, also called Fast Basic Service Set (BSS) Transition, supports VoWi-Fi handoff between access points to enable VoIP roaming on a Wi-Fi network with 802.1X authentication. See 802.11 for a complete overview of the 802.11x family of specifications.
The term used to describe the family of 802.11 specifications developed by the IEEE for wireless LAN technology. 802.11 specifies an over-the-air interface between a wireless client and a base station or between two wireless clients. See 802.11 for a complete overview of the 802.11x family of specifications.
Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs) that use a point-to-multipoint architecture. Published on April 8, 2002, the standard defines the use of bandwidth between the licensed 10GHz and 66GHz and between the 2GHZ […]
Not to be confused with 802.11x, which is the term used to describe the family of 802.11 standards for wireless LAN technology, 802.1X is the IEEE standard for port-based Network Access Control for enabling restricted use of IEEE 802 LAN service access points (ports) to secure communication between authenticated and authorized devices. See 802.11 for […]
A high-resolution video standard for PCs developed by IBM in 1987. It is designed to extend the capabilities of VGA. The 8514/A standard provides a resolution of 1,024 by 768 pixels, which gives it about 2.5 times the pixels of VGA (640 by 480). Like VGA, 8514/A provides a palette of 262,000 colors, of which […]
