History of WiFi

Prior to the Internet, a technology called packet radio was developed at the University of Hawaii in 1970. This technology uses packets to send data for communication. ALOHAnet was the pioneer in communication through wireless technology. However, this wasn’t a commercial success. Fast forward to 1999, six companies involved in wireless communications formed the Wifi Alliance as a trade association. The first wireless standard IEEE 802.11 was renamed to Wi-fi for modern usage. Though the term wifi was derived from the word hi-fi, there are other conceptions that wifi means wireless fidelity, which is not really true. This is why wifi is called wifi. 

There are 3 layers in wireless networks namely the physical layer, data link layer, and the network layer. The Internet speed is measured in Mbps (Megabits per second) and the fastest Internet speed recorded is 178TB/s. Wifi routers is a device that acts as the access point for wireless networks. These days, every household and public place has a wifi router installed to offer Internet to the people there.
