6. WHY Gi-fi?
 The reason for pushing into
Gi-Fi technology is because of
 high power consumption,
low range of frequency
operations of earlier
technologies i.e.,Bluetooth
and Wi-Fi.

The performance improvements resulting from the use of
MIMO
systems are due to
• 1. Array gain
• 2. Diversity gain
• 3. Spatial Multiplexing Gain
• 4. Interference Reduction

14. SAFETY CONCERNS OF 60GHz
WIRELESS DEVICES
• a)mm Wave systems have low power levels, millimeter-wave
systems do not penetrate the human body
• b)High frequency emissions such as 60GHz are absorbed
by moisture in the human body and thus cannot penetrate
beyond the outer layers of skin
• c)Exposure to 60GHz acceted exposure levels in the 1.5-
100 GHz band is 1 mW/cm2 averaged over 30 minutes.
• e)The occupational/controlled exposure in the same band
is 5 mW/cm2 averaged over 6 minutes.

19. TECHNICAL CONSIDERATION
• The Gigabit wireless fidelity (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 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.

20. CONCLUSION
 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.
 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.
