Technology assumes a core part of our day-to-day lives. We have made greater progress in terms of technology.one technology that is part of our day today activity is the Wi-Fi.
The smartphone and the internet we use today wouldn’t have been possible without wireless communication technologies such as Wi-Fi. In 1995 if you wanted to “surf” the internet at home, you had to chain yourself to a network cable like it was an extension cord. In 1997, Wi-Fi was invented and released for consumer use. With a router and a dongle for our laptop, we could unplug from the network cable and roam the house or office and remain online.
Over the years, Wi-Fi’s gotten progressively faster and found its way into computers, mobile devices and even cars. Wi-Fi is so essential to our personal and professional lives today that it’s almost unheard of to be in a home or public place that doesn’t have it.
Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smart phones and wearables), and other equipment (printers and video cameras) to interface with the Internet. It allows these devices–and many more–to exchange information with one another, creating a network.
Internet connectivity occurs through a wireless router. When you access Wi-Fi, you are connecting to a wireless router that allows your Wi-Fi-compatible devices to interface with the Internet.
Wi-Fi is not an acronym. It is a brand name created by a marketing firm that’s meant to serve as an interoperability seal for marketing efforts.
In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most IEEE 802.11 products are sold.
Wi-Fi uses multiple parts of the IEEE 802 protocol family and is designed to work seamlessly with its wired sibling, Ethernet. Compatible devices can network through wireless access points with each other as well as with wired devices and the Internet. Different versions of Wi-Fi are specified by various IEEE 802.11 protocol standards, with different radio technologies determining radio bands, maximum ranges, and speeds that may be achieved.
A wireless access point (AP) allows wireless devices to connect to the wireless network. Having a Cisco wireless network makes it easy to bring new devices online and provides flexible support to mobile workers.
Wi-Fi’s radio bands have relatively high absorption and work best for line-of-sight use. Many common obstructions such as walls, pillars, home appliances, etc. may greatly reduce range, but this also helps minimise interference between different networks in crowded environments.
