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.PowerPoint Presentation: Cables OpticalFiber Wireless Access Bluetooth Wi-Fi WimaxPowerPoint Presentation: 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.PowerPoint Presentation: 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 technologyPowerPoint Presentation: 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.PowerPoint Presentation: 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 NETWORKSPowerPoint Presentation: WORKING OF GI-FI It isconverted from IF range to RF60Ghz range by using 2 mixers. The incoming RF signal is first down 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 will be transferred with in secondsWHY 60 GHZ..? Millimeter wave antenna which will operate at 60Ghz frequency which is unlined band ,Because of this band we are achieving high data rates energy propagation in the 60 GHz band has unique characteristics that make possible many other benefits such as excellent immunity to co-channel interference, high security, and frequency re-use. : WHY 60 GHZ..? M illimeter wave antenna which will operate at 60Ghz frequency which is unlined band ,Because of this band we are achieving high data rates energy propagation in the 60 GHz band has unique characteristics that make possible many other benefits such as excellent immunity to co-channel interference, high security, and frequency re-use. Point-to-point wireless systems operating at 60 GHz have been used for many years for satellite-to-satellite communications. This is because of high oxygen absorption at 60 GHz (10-15 dB/Km).PowerPoint Presentation: ULTRA WIDE BAND FREQUENCY USAGE: UWB is a technology with high bit rate, high security and faster data transmission. It is a zero carrier technique with low coverage area. These features are Ultra-Wideband (UWB) is a technology for transmitting information spread over a large bandwidth (>500 MHz) that should, be able to share spectrum with other users. Regulatory settings of FCC are intended to provide an efficient use of scarce radio bandwidth while enabling both high data rate personal-area network (PAN) wireless connectivity and longer-range, low data rate applications as well as radar and imaging systems Oxygen Attenuation vs. FrequencyPowerPoint Presentation: FEATURES OF GI-FI : High speed of data transfer Low power consumption High security Cost effective Small size Quick deployment Highly portable,highmobilityPowerPoint Presentation: APPLICATIONS OF GI-FI House hold appliances : it makes the wireless home and office of the future 2. Office appliances : 3. Video information transfer:PowerPoint Presentation: 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.PowerPoint Presentation: 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.References: en.wikipedia.org www.techlivez.com www.ieee.org www.logictech.com www.technologyreview.com : References: en.wikipedia.org www.techlivez.com www.ieee.org www.logictech.com www.technologyreview.comPowerPoint Presentation: THANK YOU ALL ...PowerPoint Presentation: ANY QUIERIES ?
