This is not an advise how to secure your wireless network but rather a call to use the correct terminology, although using Wi-Fi with 802.1X in an enterprise is good practice.
The term Wi-Fi, commercially used at least as early as August 1999 was coined by brand-consulting firm Interbrand Corporation. The Wi-Fi Alliance had hired Interbrand to determine a name that was “a little catchier than ‘IEEE 802.11b Direct Sequence'”. Phil Belanger, a founding member of the Wi-Fi Alliance who presided over the selection of the name “Wi-Fi”, stated that Interbrand invented Wi-Fi as a play on words with hi-fi, and also created the Wi-Fi logo. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability. He also stated “Wi-Fi doesn’t stand for anything. It is not an acronym. There is no meaning.”
The only reason that you hear anything about “Wireless Fidelity” is that some of the founders at the Wi-Fi Alliance were afraid and they didn’t understand branding or marketing. They could not imagine using the name “Wi-Fi” without having some sort of literal explanation. So there was a compromise and there was a tag line “The Standard for Wireless Fidelity” included along with the name. This was a mistake and only served to confuse people and dilute the brand. Please note that the Wi-Fi Alliance doesn’t invent standards; the IEEE is responsible for the 802.11 standards. For the first year or so( circa 2000) , this would appear in all Wi-Fi Alliance’s communications. Later, when Wi-Fi was becoming more successful and they got some experienced marketing and business people from larger companies on the board, the alliance dropped the tag-line. But unfortunately the damage was already done and there are still tons of references to the tag-line.
The name is often written as WiFi, Wifi or wifi, but these are not approved by the Wi-Fi Alliance. Wi-Fi is the correct spelling.
Having this said people seem to like to spell it without the dash, as evidenced by the Google Trends search volume which currently indicates about 20x more searches without the dash than with the dash: http://www.google.com/trends/explore?q=wi-fi%2C+wifi#q=WiFi%2C%20Wi-Fi
This jumps to the conclusion that although Wi-Fi is the correct spelling it’s not generally used and we have to accept this. However, for all people professionally involved with wireless networks it is advisable to use Wi-Fi in all (formal) circumstances.
PS How it is pronounced should also be obvious: Wi-Fi should be pronounced as“Why-Fi” but I hear “Wiffy” a lot ; certainly in The Netherlands.
So what’s up with 802.1X? People(manufacturers, colleagues, customers and even networking professionals) spell it wrong a lot of times. Let me first explain something about the Institute of Electrical and Electronics Engineers (IEEE) and how the standards are numbered and named. The IEEE is best known for its networking standards: the IEEE 802 project. IEEE projects are subdivided into working groups to develop standards. So we have the 802.11 working group who is responsible for creating the WLAN standard. Within a particular working group, a number of task groups may be formed. For example, the “n” task group (as in 802.11n) deals with HT (High Throughput).
In the IEEE nomenclature, lowercase letters(802.11n and 802.11ac) are reserved for add-on specifications or amendments that revise an existing standard(eventually rolled into a base document). Uppercase letters or no letters are used for standalone base documents or protocol specifications.
The IEEE 802.1 Working Group is chartered to concern itself with and develop standards and recommended practices in the following areas: 802 LAN/MAN architecture, internetworking among 802 LANs, MANs and other wide area networks, 802 Security, 802 overall network management, and protocol layers above the MAC & LLC layers.
The 802.1X standard: For the purpose of providing compatible authentication, authorization, and cryptographic key agreement mechanisms to support secure communication between devices connected by 802 LANs, this standard: a) Specifies a general method for provision of port-based network access control. b) Specifies protocols that establish secure associations for IEEE Std 802.1AE MAC Security c) Facilitates the use of industry standard authentication and authorization protocols.
Don’t write 802.1x it is wrong! And please do not use 802.11x it is non-existent within the IEEE standards and sometimes used as a shorthand for the most common flavors of Wi-Fi: 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac.
802.1X is the working group that created the 802.1X standard. If you referring to this standard spell it right: with a capital X.
