The document discusses Gi-Fi (Gigabit wireless) technology, which allows wireless transfer of data at speeds up to 5 gigabits per second within a 10 meter range. It provides advantages over existing Bluetooth and Wi-Fi technologies by offering higher data rates, lower power consumption, and operating at 60 GHz frequency for better security and interference immunity. The document outlines the network evolution leading to Gi-Fi, its architecture based on IEEE 802.15.3c standard, working principles, advantages, applications in home appliances and vehicle communication, and concludes that Gi-Fi will become the dominant wireless technology for networking within five years.

GIGABIT WIRELESS TECHNOLOGY NEXT GENERATION WIRELESS TECHNOLOGY
CONTENTS o Introduction o Network Evolution o Why Gi-Fi is used o Bluetooth and Wi-Fi o Architecture and Fundamentals technologies of Gi-Fi o Working o Features /Advantages o Disadvantages o Applications o Technology Considerations o Conclusion
Introduction to Gi-Fi:  Gi-Fi or Gigabit wireless is the world’s first transceiver integrated on a single chip that operates at 60 GHz 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
Network Evolution
Man Behind Gi-Fi Technology:  Professer stan stefieds of Melbourne university
Why Gi-Fi ? o The reason of 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.
Comparison :
Disadvantages of bluetooth and Wi-Fi  The bit rates of Bluetooth is 800 Kbps and Wi-Fi has maximum of 11Mbps  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
Architecture of Gi-Fi  The core component of a Gi-Fi system is the subscriber station  It supports standard od 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 802.25.3C  It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference. It use ultra wide band which consists of: 1. High bit rate 2. High security 3. Faster data transmission
WORKING  Time division duplex  Intermediate frequency  Radio frequency  Heterodyne principle
Why 60 GHz?  Immunity to co-channel interference  High security  Frequency reuse  High oxygen absorption at 60 GHz attenuates signals over distance
Features of Gi-Fi  High speed of data transfer  Low power consumption  High security  Cost effective  Small size  Quick deployment  Highly portable
Disadvantages  The main draw back of this technology is data transfer in short distance, rane of 10 meters.  The Gifi signals are easily blocked by objects due to lesser operating wavelength.  It is less secure compare to LiFi system.
Applications of Gi-Fi • Household appliances: it makes the wireless home and office of the future. • Office appliances: as it transfers data at high speeds that made work very easy. • Video information transfer: we can transfer at a speed of Gbps . • Inter vehicle communication system:
Technological considerations  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 definitions displays.
Conclusion  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.
