Who invented wifi.?

Answer 1

Australian scientists working at the CSIRO patented Wi-fi in 1996, following work done by Dr John O'Sullivan in 1977 on how to sharpen the data coming from exploding black holes.

In 2009 Dell, HP, Microsoft, Intel, Nintendo and Toshiba paid $250 million to the Australian CSIRO in royalties.

Vic Hayes, from the Delft University of Technology in Delft, Netherlands, of the IEEE (Institute of Electrical and Electronics Engineers, Inc.), established the IEEE 802.11 set of wireless networking standards that would make wifi possible.

A:

WI-FI has its technological roots in the military. They were looking for methods of securing communications channels and one of the answers was called Spread Spectrum. Rather than communicate on a single channel, the transmitter and the receiver change frequency at a high rate of speed. Only the two ends of the communication know which frequency to transmit, or receive on at any given moment in time. This technology was not used much during world war two or the Korean War. However it saw widespread use in the Vietnam War. It was soon found that in addition to making it difficult to follow any one conversation, you could put multiple communications on at the same time and confuse the enemy even further. Military com specialists being what they were, started using spread spectrum communications in ham radio gear in the mid 1970's and started using the 2.4ghz "open" band at the technology became available in the early 1990's. As computers began to proliferate the security feature of "spread spectrum" became less and less usefull, the computers were plenty fast enough to figure out which channel to be on, and when. However the ability to multiplex many frequencies at once became more usefull in allowing the computers themselves to communicate and thus in the early 1990's Broadband Spread Spectum equipment flowered and became very popular. The first time I heard it called WiFi or Wireless Fidelity was in the range of 1995 I believe.
