Gi-Fi is a new wireless technology that allows data transfer speeds up to 5 gigabits per second within a 10 meter range, addressing limitations of existing technologies like Bluetooth and Wi-Fi which have slower speeds and higher power consumption. Gi-Fi uses 60GHz frequency and satisfies IEEE 802.15.3C standards for wireless personal area networks. It has potential applications for wireless transfer of high-definition video between devices in homes and offices. The technology is expected to become dominant for wireless networking within five years.

3. Introduction
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 at up to
5 gigabits per second to users within an indoor environment.
Gi-Fi is ten times the current maximum wireless transfer rate
usually within a range of 10 meters.
It satisfies the standards of IEEE 802.15.3C

5. Why Gi-Fi
 The reason for pushing into Gi-Fi technology
is because of
slow rate,
high power consumption,
low range of frequency operations
of earlier technologies i.e., Bluetooth and
Wi-Fi.

7. Disadvantages of Bluetooth & 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.

8. Architecture of Gi-Fi
 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.

9. 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 :
High bit rate
High security
Faster data transmission

11. Applications of Gi-Fi
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.

13. Technology Considerations
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 Wireless HD, an industry-led
effort to define a specification for the next generation consumer
electronics products.
Specifically, Wireless HD has a stated goal of enabling wireless
connectivity for streaming high- definition content between source
devices and high-definition displays.

14. Conclusio
n
 Within five years, we expect Gi-Fi to be
the dominant technology for wireless
networking.
which will develop wire less home and
office of future.
Gi-Fi can bring wireless broadband to the
enterprise in an entirely new way.
