What organization creates and manages the 802.11 standard? -
| | | | | | | | |
CORRECT ANSWER✔✔-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. - CORRECT
| | | | | | | | |
ANSWER✔✔-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. - CORRECT ANSWER✔✔-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. -
| | | | | | | | | | |
CORRECT ANSWER✔✔-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? - CORRECT ANSWER✔✔-In addition to the terms
| | | | | | | | |
standard, draft, amendment and standard as amended, it is important
| | | | | | | | | |
to know that the letters used can have significance. For example, 802.1X
| | | | | | | | | | |
|is an important standard related to modern WLAN security. It provides
| | | | | | | | | | |
the port-based authentication we used in our enterprise WLANs.
| | | | | | | | |
However, it is often mistakenly called 802.1x, when it should be 802.1X.
| | | | | | | | | | | |
What is the difference? | | |
-A lowercase letter indicates an amendment to a standard.
| | | | | | | |
-An uppercase letter indicates a standard in and of itself.
| | | | | | | | |
-802.1X is not an amendment to some earlier port-based authentication
| | | | | | | | |
standard, but it is a standard for port-based authentication.
| | | | | | | | |
In the end, an x is not an X.
| | | | | | | |
What characteristic of an RF wave defines its strength or power? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-The amplitude defines the strength of the signal.
