One of the issues related with any field of study is the use of Acronyms. My wife is a Labor & Delivery Nurse, and they have their own set of acronyms. I grew up as an Army/AirForce brat – and so was surrounded by acronyms my entire life. Then to top it off, I went through MBA school and picked up an entire other set of terms, all shortened and ‘acronymized’.
Now I’m in the Wireless LAN field and inundated by even more of these terms, terms shortened and turned into a quick way of discussing complex issues, but only referring to them in simple acronyms.
A couple of examples…we easily drop the term CCI or CCA – sometimes incorrectly interchanged even. But the huge amount of time and energy needed to design OUT Co-Channel Interference from our WLAN designs is quickly swept away with just a simple three-character acronym.
Last week’s Wireless Tech Field Day #7 was a prime example of how we all sink into the morass of even more acronyms. Ones we start using internally to quickly shorten our communications with each other, and soon we are thinking everyone knows about these and we forget that not all our communication shortcuts are shared by everyone in our audiences.
My suggestion is at a minimum to define each acronym at least once – the first time you use it – and that is just a minimum. The more times you can link the shortened name to a more descriptive name… the better your audience will be able to understand.
Sometimes these might be industry terms that are new and sometimes they can be more vendor specific and have more meaning than the simple shortened name implies.
Here are some examples in random order… with just a wee bit of my attitude thrown in for good measure:
Signal to Interference plus Noise Ratio. A better way to view how well a client will connect and be able to send data – includes interference in the equation.
Creates a consistent, flexible identiy and policy architecture when communicating with Cloud API’s.
Shore for Common Internet File System – a protocol that defines a standard for remote file access – or a very simple way to get Stephen Foskett’s blood pressure to climb.
Just as confusing as free… free as in beer, or free as in speech, or Open as a proprietary standard… yep – we are all confused – but people still like calling thing open if they want their standard to be followed by others.
Something people who work at Best Buy or Radio Shack used to call Access Points. A simple way to determine if someone is a Wireless LAN Professional, or just a wanna-be…
Software Defined Networking – I’m not even going to attempt to define this… you’re on your own for this one. Ask Tom Hollingsworth for a definition…
Fabric Attached – an Avaya term for their SDN linking all their wired and wireless components to a single fabric. See their presentation here.
Usually when talking about client devices in K-12 schools. Meaning, one device per student. Some have mistakenly thought it refers to the terrible practice of putting one access point in each classroom.
Receive Start of Packet – a Cisco technique to shrink cell sizes by limiting the Clear Channel Assessment process in their Access Points.
Multi-User MIMO – a part of 802.11ac Wave 2 that might be a bit over-hyped because it allows a Wi-Fi Access Point to talk to more than one client device at the same time.
See Harvard Business Review for better description here.
1024-QAM Cell Size
A humorous example of how we could have Access Points distributed ever 2 meters or so…
A content delivery network or content distribution network is a large distributed system of servers.
Meraki CMX API used intelligent access points to delivery real-time location analytics.
Using login credentials from other social media sources, like Facebook, Twitter, or LinkedIn as way to log into a public Wi-Fi system. A way for WLAN vendors to sell their gear to retailers and the like who want to glean personal data to sell more stuff to unsuspecting customers. (too much attitude?)
Cisco Top Hat
Not Too PHAT… You know, not a black hat, not a white hat… but a Top Hat! (@CiscoTophat)
An 802.11n 2×2:2 USB Wi-Fi NIC from Proxim – used by many software tool makers in the WLAN space – some private label their own versions.
RF Obstacle Zone
Feature in AirMagnet’s Survey Pro/Planner app to designate areas of RF attenuation. Used instead of a ‘wall’.
Web-app from AirTight used to visualize 802.11 packet captures to help troubleshoot Wi-Fi issues. You can register for @wizshark beta access here:

Mini-Display Port used for high-speed transfers and displays in daisy-chain mode.
