Gi-Fi Technology
CHAPTER 1
INTRODUCTION
Wi-Fi (ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our attention. As there are no recent developments which transfer data at faster rate as video information transfer taking lot of time. This leads to introduction of Gi-Fi technology. It offers some advantages over Wi-Fi, a similar wireless technology. In that it offers faster information rate (Gbps), less power consumption and low cost for short range transmissions. Gi-Fi which is developed on an integrated wireless transceiver chip. In which a small antenna used and both transmitter-receiver integrated on a single chip, which is fabricated using the complementary metal oxide semiconductor (CMOS) process. Because of Gi-Fi transfer of large videos, files will be within seconds. Gi-Fi or gigabit wireless is the world’s first transceiver integrated on a single chip that operates at 60GHz on the CMOS process. It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. NICTA researchers have chosen to develop this technology in the 57-64GHz unlicensed frequency band as the millimeter-wave range of the spectrum makes possible high component on-chip integration as well as allowing for the integration of very small high gain arrays. The available 7GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 meters. It satisfies the standards of IEEE 802.15.3C. The reason for pushing into Gi-Fi technology is because of slow rate, high power consumption, low range of frequency operations of earlier technologies i.e., Bluetooth and Wi-Fi. The widespread availability and use of digital multimedia content has created a need for faster wireless connectivity that current commercial standards cannot support. This has driven demand for a single standard that can support advanced
