WHY WE GO FOR GI-FI

The reason for pushing into Gi-Fi technology is because of

1. slow rate

2. high power consumption

3. low range of frequency operation of earlier technologies.

i.e. bluetooth and Wi-Fi

WIRELESS NETWORK GENERATION

APPLICATIONS

• Inter-vehicle communication system

FUTURE SCOPE• The Gi-Fi integrated transceiver chip is may be launched by

starting of next year by NICTA,Australia will be first .

• Due to less cost of chip so many companies are 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.

CONCLUTION

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

for wireless networking.

• By that time it will be to provide services with low-cost, high

broadband access, and with very high speed large files swapped

within seconds which will develop wireless 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.
