What organization creates and manages the 802.11 standard?
Ans: The Institute of Electrical and Electronics Engineers (IEEE) is an
engineering association dedicated to fostering technological innovation and
excellence for the benefit of humanity. They develop standards, in relation to
Wi-Fi, for networking communications and operations. The 802 standards
committee focuses on developing and maintaining networking standards and
recommended practices for local, metro, and other network types. Within the
unlicensed spectrum bounds defined by the FCC in North America, the IEEE
creates the 802.11 standard. For Example, 802.11 channels as defined in the
standard must fall within the FCC unlicensed ranges. Over the years new
technology has been introduced to improve the speed and reliability of
WLANs so the 802.11 standard has been amended to include additional
features.
The Wi-Fi Alliance certifies equipment to be compliant with IEEE standards
and compatible with other Wi-Fi equipment.
Ans: The Wi-Fi Alliance further defines standards within the bounds set by
the 802.11 standard. The Wi-Fi Alliance promotes interoperability between
the vendors of WLAN equipment. The Wi-Fi Alliance is an important
organization for wireless LAN (WLAN) progress. In fact, the Wi-Fi Alliance
owns the "Wi-Fi" trademark. The Wi-Fi Alliance often takes the most
important aspects of the 802.11 specifications and tests those features and
functions for multi-vendor functionality. Devices are provided by product
vendors to be tested, and if the products pass the interoperability tests, they
become Wi-Fi certified for a specific technology.
IETF standards are defined through a document called an RFC and each one
has a number.

Ans: IETF standards are defined with several details including:
-RFC number: you can search for this number in any search engine as "RFC
###" and quickly located and read the document. All IETF RFCs are freely
available online.
-Updated by: these are RFCs that make changes or additions to the current -
RFC.
-Obsoletes: this is the old version of the currently viewed RFC. When looking
at an old version of an RFC, you will see "Obsoleted by: ####" so that you
know a newer version is available.
-Contributors: the people or companies who helped to develop the standard.
-Name: the name of the standard is given in the opening title. For example, the
old version (RFC 2284) was named "PPP Extensible Authentication Protocol
(EAP)" but the new version (RFC 3748) is simply named "Extensible
Authentication Protocol (EAP)."
Regulatory domains define the 802.11 standard PHYs for each domain.
Ans: Regulatory domains define which channels are available and other
factors such as output power settings, but they do not define the PHYs.
The correct answer is 'False'.
What does a capital letter, such as the D in 802.1D, indicate about an IEEE
document?
