Gi-Fi NEXT GENERATION WIRELESS TECHNOLOGY - - DEPARTMENT OF COMPUTER SCIENCE Amara Institute of Engineering & Technology Satuluru(v), Narasaraopet(Tq) -522 409. Ph. No. 08647-218185. By P.Ramya Sruthi & M Divya Bharathi

Slide 2: 

Introduction To Gi-Fi : Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS process. Gi-Fi will allow 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.

Cables OpticalFiber Wireless Access Bluetooth Wi-Fi Wimax

Slide 4: 

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.

Slide 5: 

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

Slide 6: 

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 wirelessspan 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.

Slide 7: 

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 High bit rate High security Faster data transmission GIGABIT WIRELESS PAN NETWORKS

Slide 8: 

FEATURES OF GI-FI : High speed of data transfer Low power consumption High security Cost effective Small size Quick deployment Highly portable,highmobility

Slide 9: 

APPLICATIONS OF GI-FI House hold appliances : it makes the wireless home and office of the future 2. Office appliances : 3. Video information transfer:

Slide 10: 

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.

Slide 11: 

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.
