I want to get disadvantages of Gi-Fi technology.

ABSTRACT

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.

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.

In recent years, the technology has changed a-lot from wired connection to wireless connection. Weather it is wired connection of optical fibers or wireless connection of Bluetooth and Wi-Fi, the need for better bandwidth and data rates never ends. As still we used Wi-Fi for better data exchange rates and ranges having good network coverage but the needs always look-up for better. This need lets to the new technology that is more up-to-date and has standard data exchange rates named as Gi-Fi.

Gi-Fi or Gigabit Wireless is integrated on a single chip operating at 60GHz. About its transfer rates, it can transfer the audio and video at the rate of 5Gbps at one-ninth of cost that is approx. 10 times of current transfer rates. When it transfers the data over short distance like Bluetooth, it uses 5mm Squire Chip and 1mm wide antenna and consumes only 2mwatts of power.

As it uses very small antenna, it can be used in mobile device and this development can be great for wireless home equipment.

The Gi-Fi solves the problems of low data rates, high power consumption and low frequency range of earlier technologies as Bluetooth and Wi-Fi. As it has integrated trans-receiver (Transmitter and Receiver both on single chip) on single chip and small antenna, it can provide better transfer rates with low power consumption.
