INTRODUCTION
Communication is one of the essential parts of science that has always been a point for exchanging information among parties at location actually apart wireless technology permits services such as long-range communication. For many years cables ruled the world, optical fibers played a dominant role for its higher bit rates & faster transmission. Due to its drawback in installation caused great difficulty that forced to step into the need for wireless which can cover 9-10 meters. Next, wifi having coverage area 91 meters has brought a revolutionary solution to the problem faced by Bluetooth technology. To overcome all the present difficulties a new technology that transfers data and video information at a faster rate, we move on with new technology namely Gi-Fi. Gi-Fi provides some advantages over wireless technologies such as fast information rate in Gbps range communication.
Gi-Fi or Gigabit Fidelity is the world’s first transceiver integrated on single-chip operation at 60GHz on the devices. The world's first Gi-Fi wireless network chip developed at Australia pear federal technology incubator has entered its commercialization phase.

The GiFi chip is good news for personal area networking because there is no internet infrastructure available to cop it with. It can have a span of 10 meters. With the help of Gi-Fi chips, the video-sharing can be possible without any hurdles. The Gi-Fi chip is one of Australia's most lucrative technology. Integrated on a single chip that operates at 60GHz on the CMOS process. Gi-Fi is a wireless transmission system that is ten times faster than Wi-Fi and it’s chip delivers short-range multi-gigabit data transfer in an indoor environment. It will allow wireless transfer of audio and video data up to 5 gigabits per second, low power consumption, usually within a range of 10 meters. The size of the Gi-Fi chip is 5×5 millimeters and can be placed in different devices such as mobile phones. The best part about this new technology Gi-Fi is its cost-effectiveness and power consumption, it only consumes 2 watts of power for its operation with antenna (1mm) included and the development of Gi-Fi chip costs approximately $10 (Rs380) to manufacture.
ARCHITECTURE OF GI-FI
The core component of the Gi-Fi system is the subscriber station which available to several access points. It supports the standard of IEEE 802.15.3C. The wireless span is a computer network used for communication among computer devices close to one person. An 802.15.3C based system often uses a small antenna at the subscriber station. The antenna is mounted on the roof. It supports the line of sight operation.
