 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
allows 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.

 The reason for pushing into Gi-Fi
technology is because of
slow rate,
high power consumption,
low range of frequency operation
of earlier technologies i.e. bluetooth and wi-fi.

 The bit rates of Bluetooth is 800 Kbps and Wi-Fi
has 11 Mbps
 Both are having power consumptions 5mw and
10mw
 The lower frequency of operation 2.4GHz.

so, to have higher data transfer rate at lower
power consumption we move onto Gi-Fi technology.

The
core component of a Gi-Fi system is the
subscriber station .
It
supports standard of IEEE 802.15.3C Wireless
PAN
An 802.15.3C based system often uses
small
antenna at the subscriber station.
It supports line
of sight operation.

FUNDAMENTAL TECHNOLOGIES IN 802.15.3C
*It transmits multiple signals
simultaneously across the
wireless transmission paths
within separate frequencies to
avoid interference.
It uses ultra wide band
Which consists of :
1. High bit rate
2. High security
GIGABIT WIRELESS PAN NETWORKS
3. Faster data transmission

1. Household appliances :
It makes the wireless home and office of
the future.
2. Office appliances :
As it transfers data at high speeds that
made work very easy .
3. Video information transfer:
We can transfer at a speed of gbps.


Due to less cost of chip so many companies are
looking forward to launch with lower cost.

Specifically, Wireless HD has a stated goal of
enabling wireless connectivity for streaming
High definition content between source devices
and high-definition displays.

 Within five years, we expect Gi-Fi
to be the dominant technology for
wireless networking.
 Gi-Fi can bring wireless broadband to
the enterprise in an entirely new way.
