But how many of us know the full history behind WiFi technology? When was WiFi invented? How exactly does it work? And just how far it has. The history of WiFi is long and interesting. In , ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE protocols, respectively. They are the ones credited with inventing Wi-Fi. Marconi and Popov started experiments with the radio-telegraph shortly thereafter, and Marconi patented a complete wireless system in It was called radio because the transmitting station radiated electromagnetic waves.

This lead to the creation of IEEE Following this, a basic specification for WiFi was established, allowing two megabytes per second of data transfer wirelessly between devices.

This sparked a development in prototype equipment routers to comply with IEEE WiFi Frequencies WiFi uses electromagnetic waves to communicate data that run at two main frequencies: Claude Elwood Shannon recognized the parallels between Boolean algebra and the functioning of electrical switching systems.

Hewlett developed the Wien-bridge Wireless history oscillator. Lindenblad of RCA developed a coaxial horn antenna.
