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…show more content…
So to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology. ➢ The 802.11b and 802.11g flavours of Wi-Fi use the 2.4 GHz spectrum, which is crowded with other devices such as Bluetooth, microwave ovens, cordless phones, or video sender devices, among many others. This may cause degradation in performance. Other devices which use microwave frequencies such as certain types of cell phones can also cause degradation in performance. ➢ Power consumption is fairly high compared to other standards, making battery life and heat a concern. ➢ Not always configured properly by user. Commonly uses WEP (Wired Equivalent Privacy) protocol for protection, though has been shown to be easily breakable. Newer wireless solutions are slowly providing support for the superior WPA (Wi-Fi Protected Access) protocol, though many systems still employ WEP. CHAPTER 3 GI-FI 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
