INTRODUCTION TO GI-FI

Gigabit Fidelity or Gigabit Wireless

World's first transceiver integrated on a single chip

Fabricated using CMOS (Complementary Metal Oxide Semiconductor)

process

Wireless transfer of audio and video data within seconds

Developed at the National Information And Communication Technology

Research Center in MELBOURNE, AUSTRALIA
