• Evolution of Gi-Fi

• What is Gi-Fi

• Demerits of Bluetooth and Wi-Fi

• Architecture of Gi-Fi

• Working of Gi-Fi

• Features/Advantages

• Applications

• Technology Considerations

• Conclusion

• For many years cables ruled the world, optical fibers played a dominant

role for its faster transmission but installation of cable caused a greater

difficulty and lead to wireless access.

• Foremost was Bluetooth then Wi-Fi followed it. But man’s continuous

quest for even better technology led to the introduction of new ,more

up-to-date standard for data exchange rate i.e. Gi-Fi.

• Wi-Fi(ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our

attention. However there is no recent developments that can transfer

data at faster rate, as Video information transfer taking lot of time.

This lead to the introduction of Gi-Fi technology.

• Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a

single chip that operates at 60GHz on the CMOS process.

• Gi-Fi will allow wireless transfer of audio and video data up to 5

gigabits per second.

• Gi-Fi is ten times the current maximum wireless transfer rate usually

within a range of 10 meters.

• It was developed at the National Information And Communication

Technology Research Center in Melbourne, Australia.

• It consists of a chip that is 5mm on each side.

• The core components of a GI-FI system is the subscriber

station which available to several access points.

• It is based on standards of IEEE 802.15.3C.

• The wireless pan is computer network used for

communication among computer devices close to one person.

• An 802.15.3c based system often uses small antenna at the

subscriber station. The antenna is mounted on the roof.It

supports line of sight operation.

• Initially we make use of Time Division Duplex for both

transmission and receiving.

• Then there is a conversion of data from IF range to RF

60Ghz range.

• The incoming RF signal is first down converted to an IF

signal centered at 5 GHz and then to normal data ranges.

• We make use of heterodyne principle for this process to

avoid leakages.

• And then data is transferred.

• High speed of data transfer

• Low power consumption

• High Security

• Cost-effective

• Small size

• Quick Deployment

• Interference Immunity

• Wavelength and Antenna Size

• Frequency Reuse

• High Portability, High Mobility

The Gi-Fi integrated transceiver chip may be launched

by in the next five years by NICTA, Australia will be first .

Due to less cost of the chip, there are many companies forward

to launch with lower cost.

The potential of mw-WPAN for ultra fast data exchange has

prompted companies like Intel, LG, Matsushita (Panasonic),

NEC, Samsung, SiBEAM, Sony and Toshiba to form

WirelessHD, an industry-led effort to define a specification

for the next generation consumer electronics products.

• Within five years, we expect Gi-Fi to be the dominant

technology for wireless networking, which will develop wireless

home and offices of the future.

• We also can expect the current range of 10 meters to be

expanded and used as a broadband.

• 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.
