  3. 3. INTRODUCTION • Gi-Fi stands for Gigabit Wireless and it is worlds first transceiver integrated on a single chip. • It operates at 60 GHz on the CMOS process. • Allows wireless transfer of audio and video data at up to 5 GB per second.
  4. 4. LITERATURE SURVEY 1. Gi-Fi: Future of Wireless Technology Author : Shikhar Bahl, Rishabh Rai ,June 2015  Proposed a model in which they implement a technology which gain flexibility of infrastructure, reduce capital expenditure, gain advantages over competitors and to solve business problems. 2. Effective GI-FI Wireless Technology Author : M.karthika, A.K.SathiyaBama ,Jan 2016  Proposed that wireless dual band router and wireless dual band USB adapter are based on the next generation Wi-Fi technology, which is a new wireless computer networking standard in the 802.11 ac family.
  5. 5. 3. Gi-Fi Technology: A Technology with Standard Features Author :Rakesh Kumar Jha ,Pooja Kharga, 2015  Proposed a model that MIMO (Multiple input Multiple output) increase the capacity 10 times and the system enables significant reduction of latency on the radio interface using the low numbers. 4. A Survey on GI-FI Technology Author :Sonali B. Maind, Pravin V. Khawse, May 2015  Proposed a model that the introduction of Gi-Fi wireless network has proved a solution to Bluetooth and Wi-Fi problem, the limitations for data exchange rate and range.
  6. 6. HISTORY  It was developed at the National Information And Communication Technology Research Center in MELBOURNE,AUSTRALIA.  It can have a span of 10 meters.
  7. 7.  19th cent uary NETWORK EVOLUTION: Cables Optical Fiber Wireless Access Bluetooth Wi-Fi Wimax
  8. 8. 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.
  9. 9. COMPARISON WITH BLUETOOTH , WIFI AND GI-FI
  10. 10. Disadvantages of Bluetooth & Wi-Fi  The bit rates of Bluetooth is 800Kbps and Wi-Fi has 11Mbps .  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
  11. 11. Architecture of Gi-Fi  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.
  12. 12. 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 : 1. High bit rate 2. High security 3. Faster data transmission GIGABIT WIRELESS PAN NETWORKS
  13. 13. WORKING OF GI-FI  Use of Time Division Duplex for both transmission and receiving.  Conversion of data from IF range to RF 60Ghz range.  The incoming RF signal is first down converted to an IF signal centered at 5 GHz and then to normal data ranges.  Then use heterodyne principle for this process to avoid leakages.  And then data is transferred.

  15. 15. FEATURES OF Gi-Fi  High speed of data transfer  Low power consumption  High security  Cost effective  Small size  Quick deployment  Highly portable, high mobility
  16. 16. GI-FI CHIP
  17. 17. BENEFITS OF GI-FI  Removing cables  Low cost chip  Security  Simplicity  Enabling the future of information management
  18. 18. APPLICATIONS  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.
  19. 19. Continued….  Inter-vehicle communication system:  Broadcasting video signal transmission system in sports stadium:
  20. 20. TECHNOLOGY CONSIDERATION  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.
  21. 21. FUTURE SCOPE  Easily Embedded Into Devices  Wireless Office and Home Equipment  Great Reliability And Ability  Greater Potential  Wireless HD
  22. 22. 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 files can be swapped within seconds.  Gi-Fi can bring wireless broadband to the enterprise in an entirely new way.
