Wi-Fi Abbreviation



wi-fi logoThe first time I tried using Wi-Fi at Robinson’s Galleria, I did not know what does it mean. After asking friends on what does it actually mean and not getting any answers, I tried searching it thru Google. Apparently on the search results, the term Wi-Fi means “Wireless Fidelity.” Is there such a thing as wireless fidelity? It doesn’t make sense.

Last Friday, I searched it in Wikipedia. Apparently, “Wireless Fidelity” is incorrect and has no meaning. The correct term was actually Wi-Fi Alliance. Wi-Fi Alliance is the company that created the brand “Wi-Fi” which is intended to improve the interoperability of the wireless local area network.

ADVANTAGES OF WI-FI
1. In a local area network (LAN), cabling costs are widely reduced.
2. Areas where cables cannot be reached can be accommodated with Wi-Fi.
3. Wi-Fi chipsets price continues to drop.
4. And lastly, it’s cool!

DISADVANTAGES OF WI-FI
1. Spectrum assignments and operational limitations are not consistent worldwide.
2. Wi-FI signal occupies five channels in the 2.4 GHz resulting in only 3 non-overlapped channels in the US: 1, 6, 11, and four in Europe: 1,5,9,13.
3. Wi-Fi eats up a lot of power compared to Bluetooth and Zigbee.
4. The most common wireless encryption standard, Wired Equivalent Privacy (WEP) has been shown to be easily breakable even when correctly configured.
5. Wi-Fi networks have a limited range. Wi-Fi performance decreases as the range increases.

Feel ko tama ung Wireless Fidelity na meaning. That's what I've learn since I've heard of the term Wi-Fi. Para rin kasi yang Hi-Fi, which means High Fidelity. I think the brand Wi-Fi ay sinakyan lang nila ung name to be their brand as perhaps at that time e unpatented o unregistered o di pa naoown ng isang company ang word na yan. ung lang tingin ko.
