  3. 3. Introduction To Gi-Fi : Gi-Fi or Gigabit Wireless is the worlds firsttransceiver integrated on a single chip thatoperates at 60GHz on the CMOS process. Gi-Fi will allow wireless transfer of audio andvideo data up to 5 gigabits per second. Gi-Fi is ten times the current maximumwireless transfer rate usually within a range of10 meters.
  4. 4. Evolution of Gigabit Technology : WiMAX Bluetooth Wi-Fi Wireless Access Cables Optical Fiber
  5. 5. Man Behind Gi-Fi: Professor Stan Skafidis of Melbourne University.
  6. 6. 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. 7. Disadvantages of Bluetooth & Wi-Fi The bit rates of Bluetooth is 800Kbps and Wi-Fi has 11Mbps Both are having power consumptions 5mw and 10mw  The lower frequency of operation 2.4GHz.For transferring large amount of videos, audios, data files take hours of time. so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology
  8. 8. Architecture of Gi-FiThe core components of a GI-FI system isthe subscriber station which available to severalaccess points .It supports standard of IEEE 802.15.3CThe wireless span is computer networkused for communication among computerdevices (including telephones and personaldigital assistants) close to one personAn 802.15.3c based system often uses smallantenna at the subscriber station. The antennais mounted on the roof. It supports line ofsight operation.
  9. 9. FEATURES OF GI-FI : High speed of data transfer Low power consumption High security Cost effective Small size Quick deployment Highly portable,highmobility
  10. 10. Gi-Fi ACCESS DEVICES:
  11. 11. APPLICATIONS OF Gi-Fi 1. House hold appliances : it makes the wireless home and office of the future 2. Office appliances : 3. Video information transfer:

  13. 13. 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. 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 WirelessHD, an industry-led effort to define a specification for the next generation consumer electronics products.  Specifically, WirelessHD has a stated goal of enabling wireless connectivity for streaming high- definition content between source devices and high-definition displays.
  14. 14. CONCLUSION :Within five years, we expect Gi-Fi to be thedominant technology for wireless networking. Bythat time it will be fully mobile, as well asproviding low- cost, high broadband access, withvery high speed large files swapped with in secondswhich will develop wire less home and office offuture.If the success of Wi-Fi and the imminent wideusage of WiMAX is any indication, Gi-Fi potentiallycan bring wireless broadband to the enterprise in anentirely new way.
  15. 15. Future Work :As the range is limited toshorter distances only we canexpect the broad band with samespeed and low power consumption.
