Do you know what “Wi-Fi” stands for?

with 7 comments

I was watching Cash Cab [1], one of my favorite shows on Discovery Channel yesterday. One of the questions the host asked was “What is the full form of the abbreviation Wi-Fi [2]?” I thought I knew this for a second… yes it stands for Wireless Internet… then on second thought in a split second it did not make sense to me. I was surprised and angry that I did not know what “Fi” stands for. My guess was as good as that of the passengers in the cab and they got a second strike on that question…..

Wi-Fi stands for Wireless Fidilety according to the host of Cash cab. I was disappointed that I did not know such a simple thing after hearing this abbreviation for umpteen number of times. I did some research about this to know from background and it surprised me that the host was not entirely correct, read on, you will also know why:

Wi-Fi stands for nothing. It is a brand name, coined by a brand consulting firm called Interbrand Corporation that had been hired by the Alliance to determine a name that was “a little catchier than ‘IEEE 802.11b Direct Sequence’ [2]. Wi-Fi suggests wireless fidelity (Fidelity: to adhere to promises) and this slogan/meaning is not in use anymore.

A couple of more Fi’s:
1. Hi-Fi stands for High Fidelity
2. Sci-Fi stands for Science Fiction

Sixth sense from MIT labs

leave a comment »

I was totally amazed by watching this super cool video about the latest technological invention by a PhD candidate from MIT. Pranav Mistry [1] is the genius behind Sixth Sense, a wearable device that enables new interactions between the real world and the world of data.

This demo — from Pattie Maes’ lab at MIT, spearheaded by Pranav Mistry — was the buzz of TED [2]. It’s a wearable device with a projector that paves the way for profound interaction with our environment. Imagine “Minority Report” [3] and then some.
