  2. 2. CONTENTS  Introduction  Network Evolution  Why Gi-Fi is used  Bluetooth & Wi-Fi & Gi-Fi  Architecture of Gi-Fi  Features / Advantages  Applications  Technology Considerations  Conclusion
  3. 3. INTRODUCTION  The name itself specifies its gigabit transfer rate.  Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip.  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.

  6. 6. Why Gi-Fi ? The common Wireless technologies currently used are: Bluetooth Wi-Fi The disadvantages of existing technologies; ie  Slow rate.  High power consumption.  Low range of frequency operation. gave invention to this new technology.
  7. 7. SPECIFICATION BLUETOOTH WI-FI GI-FI Frequency 2.4Ghz 2.4Ghz NA Primary Application 10 metres 91 mts 10 mts Data transfer rate 800kbps 11Mbps 5Gbps Power consumption Low Medium Low Primary Devices Mobiles phones, PDA’s,consumer Electronics etc., Notebook computers, Desktop Computers, Servers Both areas Primary Application WPAN cable replacement WLAN Ethernet Both Development Start Date 1998 1990 Under development Comparision between Bluetooth,Wi-Fi and Gi-Fi
  8. 8. Disadvantages of Bluetooth & Wi-Fi  The bit rates of Bluetooth is 800 Kbps and Wi- Fi has maximum of 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.
  9. 9. FUNDAMENTAL TECHNOLOGIES IN 802.15.3C 9  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 3. Faster data transmission GIGABIT WIRELESS PAN NETWORKS
  10. 10. Architecture of Gi-FiThe core components of a GI-FI system is the subscriber station which available to several access points . It supports standard of IEEE 802.15.3C The wireless span is computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person An 802.15.3c based system often uses small antenna at the subscriber station. The antenna is mounted on the roof. It supports line of sight operation.
  11. 11. ATTRACTIVE FEATURES High bit rate: 5 gigabits persecond, easily swapping video,audio,data files Power consumption: 2 watt power compared to 10 watt power Security: uses IEEE 802.15.3c standards
  12. 12. Small size: 5mm perside 1mm antenna at bottom uses 60Ghz millimetre wave spectrum Easily Installed Less cost: 10$ per chip
  13. 13. Applications of Gi-Fi 13 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.
  14. 14. 4. Media access control (MAC) and imaging and others:
  15. 15. Example
  16. 16. Gi-Fi Access Devices
  17. 17. HOW IT WORKS ??
  18. 18.  Here we would use a time division duplex for both transmission and receiving.  The data files are converted from IF range to RF 60Ghz range by using 2 mixers.  We will feed this to a power amplifier, which feeds millimeter-wave antenna.  The incoming RF signal is first converted to an IF signal centered at 5 GHz ,and then to normal data ranges, here we will use heterodyne construction for this process to avoid leakages due to direct conversion.  Due to availability of 7 GHz spectrum the total data will be transferred within seconds.
  19. 19. TECHNOLOGY CONSIDERATIONS  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.  mw-WPAN for ultra fast data exchange has prompted companies like Intel, LG, Matsushita (Panasonic), NEC, Samsung, SiBEAM, Sony and Toshiba.
  20. 20.  Specifically, WirelessHD has a stated goal of enabling wireless connectivity for streaming high- definition content between source devices and high-definition displays.
  21. 21. CONCLUSION : Within five years, we expect Gi-Fi to be the dominant technology for wireless networking. By that time it will be fully mobile, as well as providing low- cost, high broadband access, with very high speed large files swapped with in seconds 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.
