IntroductionWi-Fi is a wireless technology in which data is communicated between two or more Wi-Fi-enabled electronic devices using microwaves. In most cases, microwaves with a frequency of 2.4 GHz are used for data communication. Wi-Fi is used to create a local network, wireless hotspot or even a home network. Wi-Fi technology is also used in many wireless devices such as wireless stereo headphones or wireless keyboards, mice, and other computer peripherals. It has many uses, from networking to pairing devices, it provides wireless connections. There are many other devices, such as smartphones, tablets, laptops, etc. equipped with Wi-Fi clients so they can access any Wi-Fi access point or hotspot to access data services or the Internet. ResearchWi-Fi is a well-known technology and works on the protocols defined by the IEEE (Institute of Electrical and Electronics Engineers) 802.11 standards. The name Wi-Fi is used synonymously with Wireless LAN or WLAN. Normally the range of any wireless access point is a few meters, however since it runs on microprocessor, the range is reduced with any type of obstacle such as a wall. If used in open area, the range could be extended. There are also range extenders available on the market. These range extenders are a combination of two devices, namely wireless client and wireless router or access point. They receive signals from an access point and transmit them, thus extending the range of the network. These extenders work as wireless repeaters. Technology Wi-Fi runs on microwaves with two widely used bands of 2.5 GHz and 5 GHz. It is based on standards according to the IEEE 802.11 standards. The technology is used for data packets transmitted wirelessly.
