Introduction Gi-Fi stands for Gigabit Wireless. Worlds first transceiver integrated on a single chip. It operates at 60 GHz on the CMOS process. Allows wireless transfer of audio and video data atupto 5 GB per second. Gi-Fi has ten times the current maximum wirelesstransfer rate usually within a range of 10 meters.
Why Gi-Fi ? The common Wireless technologies currently usedare: Bluetooth Wi-Fi The disadvantages of existing technologies; ie Slow rate. High power consumption. Low range of frequency operation.gave invention to this new technology.
Disadvantages ofBluetooth & Wi-Fi The bit rates of Bluetooth is 800 Kbps and Wi-Fi has11 Mbps Both are having power consumptions 5mw and10mw The lower frequency of operation 2.4GHz. So, to have higher data transfer rate at lower powerconsumption we move onto Gi-Fi technology.
Architecture of Gi-Fi The core component of a Gi-Fi system is thesubscriber station . It supports standard of IEEE 802.15.3C WirelessPAN. An 802.15.3C based system often uses smallantenna at the subscriber station. It supports line of sight operation.
Features of 802.15.3C It transmits multiple signals simultaneously acrossthe wireless transmission paths within separatefrequencies to avoid interference. It uses ultra wide band which consists of: High bit rate. High security. Faster data transmission.
Applications In wireless PAN networks. Inter-vehicle communication system. Household appliances. Office appliances. Video information transfer.
Advantages High speed of data transfer. Low power consumption. High security. Cost effective. Small size. Quick deployment. Highly portable, high mobility.
Conclusion Due to less cost of chip so many companies arelooking forward to launch with lower cost. Within five years, we expect Gi-Fi to be the dominanttechnology for wireless networking. Gi-Fi can bring wireless broadband to the enterprisein an entirely new way.
