An 802.11 wireless adapter (WNIC) can operate in two modes known as

infrastructure mode and ad hoc mode:

Infrastructure: In an infrastructure mode network the wireless adapter

needs a wireless access point or a wireless router for communication. All

wireless nodes in an infrastructure mode network connect to an access point

or a wireless router.

Ad-hoc: A wireless ad hoc network does not rely on a preexisting

infrastructure, such as routers in wired networks or access points in

managed (infrastructure) wireless networks. It typ ical ly refe rs to any se t

of network s where all devic es have equal status on a ne twor k and

are free to associate with any other ad hoc network device in link range in

peer to peer communication mode.

Appendix 2 Glossary

802.11ac: IEEE 802.11ac is a wireless computer networking standard of

802.11, currently under development, providing high-throughput wireless

local area networks on the 5 GHz band. Theoretically, this specification will

enable multi-station WLAN throughput of at least 1 gigabit per second and a

maximum single link throughput of at least 500 megabits per second (500

Mbit/s).

802.11a: 802.11a is an amendment to the IEEE 802.11 specification that

added a higher data rate of up to 54 Mbit/s using the 5 GHz band.

802.11b: 802.11b, is an amendment to the IEEE 802.11 wireless

networking specification that extends throughput up to 11 Mbit/s using the

same 2.4 GHz band.

802.11e: 802.11e is an approved amendment to the IEEE 802.11 standard

that defines a set of Quality of Service enhancements for wireless LAN

applications through modifications to the Media Access Control (MAC) layer.

The standard is considered of critical importance for delay-sensitive

applications, such as Voice over Wireless LAN and streaming multimedia.

802.11g: 802.11g is an amendment to the IEEE 802.11 specification that

extended throughput to up to 54 Mbit/s using the same 2.4 GHz band as

802.11b.

802.11h: 802.11h, refers to the amendment added to the IEEE 802.11

standard for Spectrum and Transmit Power Management Extensions. It

solves problems like interference with satellites and radar using the same 5

GHz frequency band. It was originally designed to address European

regulations but is now applicable in many other countries.

Wireless AC Dual-band USB Adapter

54

802.11i: 802.11i, implemented as WPA2, is an amendment to the original

IEEE 802.11.

802.11j: 802.11j is an amendment to the IEEE 802.11 standard designed

specially for Japanese market.

802.11n: 802.11n is an amendment to the IEEE 802.11 standard, which

improves network throughput over the two previous standards—802.11a

and 802.11g—with a significant increase in the maximum net data rate.

802.11n standardized support for multiple-input multiple-output and frame

aggregation, and security improvements, among other features.

IEEE 802.15: IEEE 802.15 is a working group of the IEEE 802 standards

committee which specifies Wireless Personal Area Network (WPAN)

standards. It includes seven task groups. Task group one is based on

Bluetooth technology.

IEEE 802.16: IEEE 802.16 is a series of Wireless Broadband standards

authored by the Institute of Electrical and Electronics Engineers (IEEE).

Although the 802.16 family of standards is officially called Wireless MAN in

IEEE, it has been commercialized under the name “WiMAX” (from

"Worldwide Interoperability for Microwave Access") by the WiMAX Forum

industry alliance.

802.16a: 802.16a, also known as WiMAX, extends throughput up to

70Mbit/s transmission rate within the distance of 30 miles.

802.20: Delivers 1Mbit/s throughput for wireless MAN (Metropolitan area

network).

IEEE 802.1X: IEEE 802.1X is an IEEE Standard for port-based Network

Access Control (PNAC). It is part of the IEEE 802.1 group of networking

protocols. It provides an authentication mechanism to devices wishing to

Wireless AC Dual-band USB Adapter

55

attach to a LAN or WLAN.IEEE 802.1X defines the encapsulation of the

Extensible Authentication Protocol (EAP) over IEEE 802 which is known as

"EAP over LAN" or EAPOL.

WEP: Wired Equivalent Privacy (WEP) is a security algorithm for IEEE

802.11 wireless networks. Introduced as part of the original 802.11

standard, its intention was to provide data confidentiality comparable to that

of a traditional wired network.

WPA: Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2)

are two security protocols and security certification programs developed by

the Wi-Fi Alliance to secure wireless computer networks. The Alliance

defined these in response to serious weaknesses researchers had found in

the previous system, WEP (Wired Equivalent Privacy) and intended as an

intermediate solution to WEP insecurities.

RSN: The Wi-Fi Alliance refers to their approved, interoperable

implementation of the full 802.11i as WPA2, also called RSN (Robust

Security Network). RSN, based on 802.1x, is introduced to supersede the

security specification, WPA.
