For many years, cables ruled the world. Optical fibers played a dominant role because of 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 9-10metres. Wi-Fi followed it having coverage area of 91metres. No doubt, introduction of Wi-Fi (Wireless Fidelity) has brought a revolutionary solution to â€œlast mileâ€ 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 one hand, and hard-wire networks, on the other. But the manâ€™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 .It will help to push wireless communications to faster drive.
Gi-Fi(Gigabit Fidelity) 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 mw of power to transmit data wirelessly over short distances, much like Bluetooth.
The development will enable the truly wireless office and home in 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 paper we present a low cost, low power and high broadband chip, which will be vital in enabling the digital economy of the future.
