Gi-Fi : Seminar Report and PPT
Definition of Gi-Fi
Gi-Fi will helps to push wireless communications to faster drive. For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt, introduction of Wi-Fi wireless networks has proved a revolutionary solution to “last mile” problem.However, the standard's original limitations for data exchange rate and range, number of channels, high cost of the infrastructure have not yet made it possible for Wi-Fi to become a total threat to cellular networks on the one hand, and hard-wire networks, on the other. But the mans continuous quest for even better technology despite the substantial advantages of present technologies led to the introduction of new, more up-to-date standards for data exchange rate i.e., 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 up to 5 gigabits per second, ten times the current maximum wireless transfer rate,at one-tenth of the cost,usually within a range of 10 meters.It utilizes a 5mm square chip and a 1mm wide antenna burning less than 2 watts of power to transmit data wirelessly over short distances, much like Bluetooth.
The development will enable the truly wireless office and home of the future. As the integrated transceiver is extremely small, it can be embedded into devices. The breakthrough will mean the networking of office and home equipment without wires will finally become a reality.
There are many usage cenarios that can be addressed by Gi-Fi. The following are some mobility usage applications of Gi-Fi.
House hold appliances:
Consumers could typically download a high definition movie from a kiosk in a matter of seconds to a music player or smart phone and having got homecould play it on a home theatre system or store it on a home server for future viewing, again within a few seconds. high speed internet access, streaming content download
(video on demand, HDTV, home theater, etc.), real time streaming and wireless data bus for cable replacement It makes the WIRELESS HOME AND OFFICE OF THE FUTURE
Within five years, we expect Gi-Fi to be the dominant technology for wireless networking. By that time it will be fully mobile, as well as providing low- cost, high broadband access, with very high speed large files swapped with in seconds which will develop wire less home and office of future.
If the success of Wi-Fi and the imminent wide usage of WiMAX is any indication, Gi-Fi potentially can bring wireless broadband to the enterprise in an entirely new way.
