Wi- Fi – You Use It, But Do You What It Is, Really?

Although it is an increasingly popular technology, there are some Net users who don’t have a clue as to what Wi-Fi is. This guide will explain Wi-Fi technology, what it can do, and its many advantages.

Summary of Facts

Wi-Fi (WiFi and wi-fi are also acceptable) is a technology that makes it possible for you to use an electronic gadget without wires over networks like a high speed web connection. With it you can exchange data with ease. All Wi-Fi technology is set upon the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards. Because the majority of WLAN (wireless local area networks) use Wi-Fi, WLAN and Wi-Fi are used interchangeably.

Many electronic devices can use Wi-Fi including digital audio players, tablets, smartphones, video gaming consoles, laptops, desktop computers and various gadgets. All you have to do is hook up to a hotspot or wifi access point. Most have a range of 65 feet (20 m) or more. A hotspot’s coverage may be confined to a single room or it can cover an entire city. Large scale coverage is made possible by access points that overlap.

Accessing the Internet

As long as the device is Wi-Fi enabled, it can link up to a wireless hotspot. Once confined to experimental areas, wireless connections are now available in public spaces, independent businesses, high street chains and homes. Wireless services may require payment or be free of charge.

Places with high traffic like restaurants, hotels and airports frequently have wireless services to entice people. Services may be provided by private companies or the government. In many homes and establishments, routers are used with a cable modem or line modem and a wireless access point so they have Internet access.

Some routers are powered by batteries and have a wireless access point and cellular mobile Internet radiomodem. Used in conjunction with a mobile phone carrier, you’ll be able to access 3G and 4G networks. This feature is available in popular smartphones like iOS and Android.

Benefits of Wi-Fi

Wireless connections make LAN deployment more affordable. Furthermore, wireless connections eliminate the need for cables. This is one of the most attractive features of Wi-Fi, as cables cannot be used in places like historical buildings and the outdoors. Because of its popularity, most laptop manufacturers have wireless network adapters built in.

Unlike the earlier versions, Wi-Fi Protected Access encryption (WPA2) is regarded as secure as long as the passphrase is robust. There are now mechanisms built in so battery life is extended and new protocols are put in place so applications like voice and video can be supported.


If the wireless access point is 802.11g or 802.11b, the range will be from 120 ft to 300 ft outdoors. With IEEE 802.11n the range is doubled. The range will also be influenced by the frequency band. The 2.4 GHz frequency block has a superior range to the 5 GHz frequency. If your router has a detachable antenna, you can get a better range by upgrading the antenna. There are high range antennas that can extend wireless signals by a significant amount.

Now that you know what Wi-Fi is, you will be in a better position to buy the device. There are different types of routers and they have various specs. But knowing the facts will help you understand the jargon better.
