Wi-Fi (ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our attention. As there is 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 in Gbps ,less power consumption and low cost for short range transmissions.
Gi-Fi?? which is developed on a integrated wireless trnsceiverchip.In which a small anteena 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 with in seconds.
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 man?s 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 5gigabits 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 2watts 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. In this we present a low cost, low power and high broadband chip, which will be vital in enabling the digital economy of the future.
