Wi-FI

 

What does WiFi Stand for ?

Ever wonder what Wi-Fi stand for, the most common term use by tech community is “Wireless Fidelity”.  Which means a local area network that uses high frequency radio signals to transmit and receive data over distances that uses Ethernet protocol.

Well if you dig deeper “Wi-Fi” is not an abbreviation. In 1999, several visionary companies came together to form a global non-profit association with the goal of driving the best user experience, regardless of brand, using a new wireless networking technology. In 2000, the group adopted the term “Wi-Fi® as the proper name for its technical work and announced its official name: Wi-Fi Alliance®.

How it Works ?

Like mobile phones, a WiFi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection.

As the wireless network works as a two-way traffic, the data received from the internet will also pass through the router to be coded into a radio signal that will be received by the computer’s wireless adapter.

WiFi Frequencies

WiFi Transmits at frequencies of 2.4 GHz or 5 GHz. These frequencies are much higher than the frequencies uses for cellular transmission. Higher frequency means that signals can carry more data.

However, all forms of wireless communication represent a trade off between power consumption, range, and bandwidth. So in exchange for high data rates, WiFi consumes a lot of power and doesn’t have a lot of range.

There Are Many Kinds of WiFi Standards

I’m not going to details on each of the WiFi standard as below, as it will get too technical. Each of these standards comes with various pros/cons related to data speed, signal interference from outside sources, and cost. Cost is a factor because different hardware is needed for different standards, though newer versions are made to be backwards compatible with older versions.
