The early predecessor of WiFi was launched in Hawaii in 1979. The ALOHAnet was a computer networking system that allowed the first public demonstration of a wireless packet data network. Just like any other product launch, the timing is very important nevertheless how advanced the technology may be. It took 20 years before AT&T Corporation and NCR Corporation developed WaveLAN, which is now being considered the true predecessor of WiFi unlike the ALOHAnet. Following after, the IEEE 802.11 wireless protocol has been released.
