Gi Fi Or Gigabit Wireless

Gi Fi Or Gigabit Wireless Gi-Fi will helps to push wireless communications to faster drive. For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt, introduction of Wi-Fi wireless networks has proved a revolutionary solution to last mile problem. However, the standards original limitations for data exchange rate and range, number of channels, high cost of the infrastructure have not yet made it possible for Wi-Fi to become a total threat to cellular networks on the one hand, and hard-wire networks, on the other. But the mans continuous quest for even better technology despite the substantial advantages of present technologies led to the introduction of new, more up-to-date standards for data exchange rate i.e., Gi-Fi. Gi-Fi or Gigabit Wireless is the worlds first transceiver integrated on a single chip that operates at 60GHz on the CMOS process. It will allow wireless transfer of audio and video data up to 5gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth of the cost, usually within a range of 10 meters. It utilizes a 5mm square chip and a 1mm wide antenna burning less than 2watts of power to transmit data wirelessly over short distances, much like Bluetooth. The development will enable the truly wireless office and home of the future. As the integrated transceiver is extremely small, it can be embedded into devices. The breakthrough will mean the networking of office and home equipment without wires will finally become a reality. In this we present a low cost, low power and high broadband chip, which will be vital in enabling the digital economy of the future. INTRODUCTION: Wi-Fi (IEEE-802.11b) and Wi-Max (IEEE-802.16e) have captured our attention, as there are no recent developments in the above technologies which cannot transfer data and video information at a faster rate and led to the introduction of Gi-fi technology. It offers some advantages over Wi-Fi, a similar wireless technology, that offers faster information rate in Gbps less power consumption and low cost for short range transmissions. Gi-Fi or Gigabit Wireless is the worlds first transceiver integrated on a single chip in which a small antenna used and both transmitter- receiver are integrated on a single chip which is fabricated using the complementary metal oxide semiconductor (CMOS) process. Because of Gi-Fi transfer of large videos, files can be done within seconds. Researchers of Melbourne University has come up with a wireless technology which promises high speed short range data transfers with a speed of up to 5Gbps within a radius of 10 meters. The new wireless technology is named as Gi-Fi and operates on the 60GHz frequency band, which is currently mostly unused. The Gi-Fi Chip developed by the Australian researchers measures 5mm square and is manufactured using existing complementary metal-oxide-semiconductor (CMOS) technology, the same system that is currently used to print silicon chips. The best part about this new technology is its cost effectiveness and power consumption, it consumes only 2watts of power for its operation with antenna (1mm) included and the development of Gi-Fi chip costs approximately $10( Rs 380) to manufacture. In theory this technology would transfers GBs of your favorite high definition movies in seconds. So Gi-Fi can be considered as a challenger to Bluetooth rather than Wi-Fi and could find applications ranging from new mobile phones to consumer electronics. REASONS FOR OPTING 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 GI-FI: Gi-Fi or gigabit wireless is the worlds first transceiver integrated on a single chip that operates at 60GHz on the cmos process. It will allow wirelesss transfer of audio and video data at up to 5gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. NICTA researchers have chosen to develop this technology in the 57-64GHz unlicensed frequency band as the millimeter-wave range of the spectrum makes possible high component on-chip integration as well as allowing for the integration of very small high gain arrays. The available 7GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 metres .It satisfies the standards of IEEE 802.15.3C .The Gi-Fi integrated wireless transceiver chip developed at the National ICT Research Centre, Australia A new silicon chip developed in Melbourne is predicted to revolutionize the way household gadgets like televisions, phones and DVD players talk to each other. The tiny five-millimeter-a-side chip can transmit data through a wireless connection at a breakthrough five gigabits per second over distances of up to 10 meters. An entire high-definition movie could be transmitted to a mobile phone in a few seconds, and the phone could then upload the movie to a home computer or screen at the same speed. The Gi-Fi was unveiled today at the Melbourne University-based laboratories of NICTA, the national information and communications technology research centre. Short-range wireless technology is a hotly contested area, with research teams around the world racing to be the first to launch such a product. Professor Skafiadas said his team was the first to demonstrate a working transceiver-on-a-chip that uses CMOS (complementary metal-oxide-semiconductor) technology the cheap, ubiquitous technique that prints silicon chips. This means his team is ahead and stood in front of the competition in terms of price and power demand. His chip uses only a tiny one-millimeter-wide antenna and less than two watts of power, and would cost less than $10 to manufacture. Chip of Gi-Fi The chip shown in the above figure uses the 60GHz millimeter wave spectrum to transmit the data, which gives an advantage over Wi-Fi (wireless internet). Wi-Fis part of the spectrum is increasingly crowded, sharing the waves with devices such as cordless phones, which leads to interference and slower speeds. But the millimeter wave spectrum (30 to 300 GHz) is almost unoccupied, and the new chip is potentially hundreds of times faster than the average home Wi-Fi unit. However, Wi-Fi still benefits from being able to provide wireless coverage over a greater distance TECHNOLOGIES USED This mmWave WPAN will operate in the new and clear band including 57-64 GHz unlicensed band defined by FCC 47 CFR 15.255. The millimeter-wave WPAN will allow high coexistence (close physical spacing) with all other microwave systems in the 802.15 family of WPANs. Two Technologies that help realize GWLAN are, Multiple Input Multiple Output (MIMO) System-On-a-Package(SOP) APPLICATIONS There are many usage scenarios that can be addressed by Gi-Fi. The following are some applications of Gi-Fi . Gi-Fi access devices: Gi-Fi access devices Some of the Gi-Fi access devices are shown in fig.These access devices include termination units, internal radio modules, network interface cards ,printers, PCs,and all household electronic appliances. Broadcasting video signal transmission system in sports stadium : Broadcasting video signals Easy and immediate construction of temporal broadband network such as in sports stadium for the advertisement of information distribution can be possible as shown in fig Office appliances: Office appliances As gi-fi data transfer rate is very high we can transfer data at very high speed in offices as shown in fig 7.0.3 which made work very easy and it also provides high quality of information from the internet. Video information transfer: Video information transfer By using present technologies video swapping takes hours of time where as with this technology as shown in fig 7.0.4 we can transfer data at a speed of giga bits/sec same as that for the transfer of information from a PC to a mobile and vice-versa. FUTURE SCOPE: As the integrated transceiver is extremely small, it can be embedded into devices. The breakthrough will mean the networking of office and home equipment without wires will finally become a reality. The Gi-Fi integrated transceiver chip may be launched by the starting of next year by NICTA. Due to the less cost of chip so many companies are coming forward to launch the chip. The potential of mmwave range for ultra fast data exchange has prompted many companies like intel, LG, Panasonic, Samsung, Sony Toshiba to form wireless HD. Specifically wireless HD has a stated goal of enabling wireless connectivity for streaming high definition content between source devices and high definition devices. CONCLUSION: Within five years, we expect Gi-Fi to be the dominant technology for wireless networking. By that time it will be to provide services with low-cost, high broadband access, and with very high speed large files swapped within seconds which will develop wireless 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.

The Three Waves of Feminism

The Three Big Waves of Feminism First-Wave Feminism: Women’s Right to Vote In 1776, the then First Lady of the United States was the first to raise her about women’s rights, telling her husband to â€Å"remember the ladies† in his drafting of new laws, yet it took more than 100 years for men like John Adams to actually do so. With the help of half a dozen determined, and in this case white upper-middle-class, women the first-wave feminism, which spans from the 19th century to the early 20th century, finally led to their goal after 72 years of protesting. The Nineteenth Amendment, which secured the rights for women to vote finally passed in 1920.This grand victory brought other reforms along, including reforms in the educational system, in healthcare and in the workplace. Second-Wave Feminism: Personal Means Political The First-Wave was significant to feminism as it established a safe footing from where women could start off. The second wave of feminism, however, was crucial to everything that followed after. This wave marked everything the early 1960's to the late 1980's. Of course feminism didn’t die out completely, in between the first and second wave feminism, as the media tried to make many people believe.In fact feminism was still a topic among women; they just didn’t crowd at polling stations anymore. Instead many small groups of women activists were fighting for birth control or the women peace movement. Then, during the Second World War women suddenly played a major role as work forces and could get a taste of independency. Though after the war, now that the men were back with their glorified heroism, it was expected of women to silently head back into the kitchen and act out their â€Å"natural† role as mother and wife, which has been pressed onto them from the very start. You can read also WavesObviously that didn’t sit well with many of them. However before the the Women’s Liberation movement and before the Sexual Revolution in 1968, there have been the Civil Rights Movement and the antiwar movement. Those two were the first two major social movements to be displayed through television, as well as they were the forerunners of the following feminist movement. They showed that women, too, could become political. Women from Rosa Parks to Coretta Scott King made political protest seem necessary and encouraged many women all over America, regardless of race and ethnic background, to speak up for their rights.It was the feminist movement’s turn then to get real personal and by getting real personal it didn’t get any less political. Women had enough of the sexual harassment and domestic violence going on behind doors, of being kept out of law and medical schools and thus being restricted to low paid jobs, of being confined not on ly in domestic but also in public spheres. To make it short: women had enough of being looked down at. With these problems the key demands of this movement were: â€Å"the right to safe and legal abortion, the right to accessible and affordable childcare, and the equal opportunities in education and employment†.Another demand was more support of battered women's shelters, and changes in custody and divorce law. This wave of feminism brought up the most of changes regarding women and laws. Affirmative Action rights for women were extended and acts like the Women’s Educational Equity Act, which allowed educational equality for women, the Pregnancy Discrimination Act, which prohibited â€Å"sex discrimination on the basis of pregnancy†, were passed. Amongst these acts a law passed in 1975 that required the U. S.Military Academies to admit women, as well as marital rape was made illegal and the no-fault divorce legal. Even though the last two laws were not recognize d by all states, it was still considered an enormous success. In the early 1980s the biggest strength of the second wave, the grand diversity of feminism and organisations, suddenly became its biggest weakness as the media started the so called â€Å"feminist sex wars† by pitting women, especially two of them, against each other, trying to destroy the image of sisterhood pointedly.Even though the Women’s Liberation movement clearly refused to pick a leader, the media singled out Gloria Steinem as the leader of this movement. Gloria Steinem was a single and childless career woman, who compared marriage to prostitution and insisted that â€Å"if men could get pregnant, abortion would be a sacrament†. On the other side there was the media’s darling Phyllis Schlafly, who almost single-handedly brought down the Equal Rights Amendment. Also known as the ERA, this mendment demanded that the â€Å"equality of rights under the law shall not be denied nor abridged by the United States or any state on the account of sex†. It was first introduced by Alice Paul in 1923, a woman truly ahead of her time, but didn’t get ratified by enough states to get legalized. Whether this happened because of Phyllis Schlafly herself or the way media presented the feminists of that time is debatable. In the end the ERA may not have gotten legalized and women were still oppressed, but sisterhood was very much alive and blooming.In sisterhood women found strength and with this new found strength they started breaking the blockades which had been keeping them from climbing the career ladder and decided that it was long past time to start taking charge of their own lives. Third-Wave Feminism: Finally Diversity After ERA was defeated, a vast amount of media coverage over the supposed â€Å"death of feminism† appeared on the TV screen of Americans. Those who truly believed them were surely gobsmacked by the third wave of feminism which found its s tart in the mid-90’s.Caused by the Clarence Thomas confirmation hearings and the evident spite and disdain the accuser, Anita Hill, was met with by the all-male jury, women decided that once men crossed one line too many. The most obvious difference between the third wave movement and its sisters the first and second wave movements was the embracement of diversity. With feminism becoming global it became available for women of any race as well as any social class, but also threw away the mass media’s â€Å"ugly braless bubblehead† stereotype of feminists with women like Pinkfloor stating: â€Å"†It's possible to have a push-up bra and a brain at the same time. Being feminine and a feminist was no longer mutually exclusive and with the so-called â€Å"grrl† feminists, women started to show up as strong and empowering, while reclaiming everything feminine, from wearing high-heels to lipstick. The key demands of the Third Wave are much harder to pin p oint, as the range of issues grew by women not only concerning themselves with the gender oppression but with economic oppression and environmental issues as well.However one crucial aspect was the deconstruction of categorical thinking and its endless attack on unrealistic beauty ideals set for women ever since television was invented. The third wave of feminism has not ended yet. It is history in the making, as new issues to deal with arise as soon as old ones are solved. The probably greatest achievement of these waves is the awareness of oppression they’ve spread, the feeling of community between women they created as well as turning feminism from an abstract thought into a widely accepted truth.

Modern Day America By John Milton s Paradise Lost Essay

When the â€Å"Founding Fathers† of America laid the foundation of the United States, they strove to create a society in which â€Å"all men are created equal† (Jefferson, n.p.). Despite this noble ideology, however, the subordinate status of women at the time as well as a booming slave trade prevented our nation from truly achieving this utopian vision. Now, over 200 years later, modern-day America still struggles in achieving true equality for all citizens. While women in the United States have inched closer to equality than ever before and appear to possess the same rights as men, underlying issues persist. Lingering concepts of traditional gender roles, a disturbing sexual double standard effectively encouraging â€Å"rape culture,† and the fact that women still receive less than men for the same vocation combine to prevent true equality of the sexes even today. Various literary, musical, and visual forms of art reinforce and perpetuate notions of female inferiority in the minds of many individuals using a plethora of techniques. John Milton’s Paradise Lost (1667, 1674) and Temptation of Adam and Eve (1425) by Masolino, for example, appear to accomplish this by tying sexism to the Fall of humanity in the Garden of Eden. On one hand, both Milton’s epic poem and Masolino’s Fresco point to the idea that Eve, and therefore woman, should be blamed for original sin.
