Gi-Fi TechnologyNEXT GENERATION WIRELESS TECHNOLOGY Presented by : under GUIDANCE OF : ANKIT VERMA DR. SHAHANAZ AYUB (Associate Prof.) Electronics & Comm. Engg.(3rd Year) Department Of Electronics & Communication Roll No. - 1304331007 Engineering
CONTENTSIntroduction Network Evolution Why Gi-Fi is used Bluetooth , Wi-Fi & Gi-Fi Architecture of Gi-Fi Features / Advantages Applications Technology Considerations Conclusion
INTRODUCTIONThe name itself specifies its gigabit transfer rate.It was developed in 2008 at the National Information And Communication Technology Research Center in MELBOURNE,AUSTRALIA.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.It refers to wireless communication at a data rate of more than 1 billion per second.

Why Gi-Fi ?The common Wireless technologies currently used are:BluetoothWi-FiThe disadvantages of existing technologies; i.e.Slow rate.High power consumption.Low range of frequency operation.All this gave invention to this new technology.

Comparison between Bluetooth, Wi-Fi and Gi-Fi
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.
FUNDAMENTAL TECHNOLOGIES IN 802.15.3C
8It 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 rateHigh securityFaster data transmission
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.
ATTRACTIVE FEATURESHigh bit rate: 5 gigabits persecond, easily swapping video,audio,data filesPower consumption: 2 mill-watt power compared to 10 watt powerSecurity: uses IEEE 802.15.3c standards
Small size: 5mm preside 1mm antenna at bottom uses 60Ghz millimeter wave spectrumEasily InstalledLess cost: 10$ per chip
Applications of Gi-Fi12Household 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.
Gi-Fi Access Devices
Herewe 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.
TECHNOLOGY CONSIDERATIONSThe Gi-Fi integrated transceiver chip is may be launched by starting of next year by NICTA,Australia. 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, Si-BEAM, Sony and Toshiba.
Professor Stan Skafidis The Man Behind Gi-Fi16
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.
