Wireless Fidelity
Wireless fidelity is a term that has become popular in the technology space as the full version of the abbreviation Wi-Fi, though that is a misconception and not true in any sense. Wi-Fi as a term is not even an abbreviation. It refers to the IEEE (Institute of Electrical and Electronics Engineers) 802.11 wireless LAN standards. The idea of Wi-Fi being the abbreviation of Wireless Fidelity came from the abbreviation hi-fi leading to high fidelity. Apart from this play on words, there is no other possible definition for the term wireless fidelity.
In the year 1999, an alliance, known as Wireless Ethernet Compatibility Alliance (WECA) entrusted the marketing company Interbrand with the work of coming up with a captivating brand name and logo for IEEE 802.11b direct sequence. The company delivered a list of names, among which was the chosen name Wi-Fi, apart from discarded names like Trapeze, Skybridge, Hornet, and Dragonfly.
Wi-Fi networks are not linked by any physical wired connections between sender and receiver. Using Radio Frequency Technology, which is a frequency within the electromagnetic spectrum; an RF current is supplied to an antenna which generates an electromagnetic field and transmits through space. The crux of Wi-Fi is an access point (AP) because the job of an access point is to propagate a wireless signal that computers can perceive and tune into. This type of connection to an access point requires the computers or devices to be outfitted with wireless network adapters. According to the ‘Wi-Fi alliance’ – the organization behind the registered trademark of Wi-Fi defines it as any “wireless local area network (WLAN) products that are established on the IEEE 802.11 standards.
Home networks, PDAs, video game consoles, mobile phones, major operating systems and other types of consumer electronics support Wi-Fi. As long as the product is tested and certified by the Wi-Fi alliance, it is interoperable with each other. Even if the manufacturers differ. Products that pass this test should ensure that they carry a distinguishing seal on their packaging that reads – “Wi-Fi Certified” along with the partnering RF.
