Wi-Fi stands for Wireless Fidelity and defines a technological advancement that enables electronic devices to exchange data wirelessly over certain computer networks. The term “Wi-Fi” was first introduced in 1999 to describe a local area network that provided wireless Internet. All Wi-Fi certified products, including PCs, laptops, tablets, video-game consoles, smartphones, and digital audio players, are interoperable with each other and can be connected to any Wi-Fi network. This means that these products are no longer intended for fixed-point Internet sources.
What Is Wi-Fi Used For?
To get the best out of Wi-Fi, it’s important to understand how this technology is used. If you want to connect a device to a Wi-Fi network, it has to be equipped with a special interface controller capable to detect wireless networks. Since Wi-Fi interface controllers use a single radio channel to communicate with each other, transmissions are received by all devices packed with such controllers.
Additionally, a carrier wave must be used to tune the radio frequency constantly, pick up available transmissions, and transmit data from one device to another. As you may already know, Wi-Fi can help you complete a variety of tasks, such as:
- connect to the Internet wirelessly
- control devices connected to a Wi-Fi network with your smartphone
- send documents to your printer from your phone, tablet, or computer
- forward data from your smartphone to computers
- stream movies to any TV connected to your Wi-Fi network
- share files with nearby PCs
- tether your phone to your computer for Internet anywhere
- stream audio to speakers
- transfer photos from your digital camera to TVs or PCs wirelessly
- sync your photo library, music library, and other files with your smartphone
A great aspect is that Wi-Fi allows you to perform numerous assignments, which aren’t just related to the Internet. Another thing that you must be aware of is that the coverage of a wireless network can extend from a small area, formed from a few rooms, to very large areas. Coverage in large areas requires multiple access points, which provide overlapping networks. These days, the latest technologies make possible city-wide wireless networks, ensuring amazing Internet speeds, such as 3G and 4G.
A Few Advantages
Wi-Fi delivers some great advantages, allowing you to eliminate cabling and switches, connect to the Internet almost anywhere, get in touch with friends and family, access information easily and quickly, check emails, play games, listen to music, watch movies, and even work while on the go. In conclusion, Wi-Fi is incredibly convenient.
