Gi-Fi is a wireless technology that provides data transfer rates of over 1 billion bits (1 gigabit) per second. It was developed by Professor Stan Skafidas in Australia to allow high-speed transfer of audio and video wirelessly up to 5 gigabits per second. Gi-Fi uses an ultra wide band architecture with integrated transceiver chips to transmit multiple signals simultaneously across separate frequencies for interference avoidance and faster data transmission rates than existing wireless technologies like Bluetooth and Wi-Fi, while achieving lower power consumption. Potential applications of Gi-Fi include wireless transfer for household appliances, office devices, video broadcasting, and inter-vehicle communication systems.
