Wi-Fi - Research Paper ExampleIt is the name given to a theatrical role of network connection that does no need any cords or physical connections to connect. Technically, it represents a lawsuit of Wireless Local Area Network (WLAN) that adheres to the 802.11network standard of the IEEE. The term Wi-Fi is often mistakenly thinking of as an acronym for Wireless Fidelity. What is its History? The AT&T Companys radio uses spread spectrum radio engine room and multi carrier OFDM radio technology. This spread spectrum technology used in Wi-Fi was first introduced in the year 1985 by the US Federal communications Commission. Vic Hayes chaired IEEE for ten consecutive years. He was involved in pattern standards 802.11a and 802.11b upon which Wi-Fi works. He is thus named as the father of Wi-Fi. The actual predecessor to Wi Fi was invented in 1990 by the NCR Corporation/AT&T in the Netherlands. WaveLan was the name given to the first wireless products that were bought into the market. They incorporated the speeds of 1Mbit/s to 2Mbit/s. Finally, the CSIRO, an Australian query body filed the original patents behind the Wi-Fi technology in the year 1986. How it works? Wi-Fi uses radio waves to transmit the study across a Wireless Local Area Network. It transmits cultivation to and from the internet. Any data transfer from a website is done when the website enraptures information to the modem. This information is then passed on to a wireless router. This device routes data (converts information to radio waves and beams it) to your computer. This information is then interpreted by the computer with the help of wireless networking specific ironware/software. Exactly the same process occurs but only in the opposite direction when the computer wants to send information over the internet. Very often, a wireless connection operates faster than a wired broadband internet connection. Who invented? An Australian research body CSIRO was the first formal inventors of Wi- Fi in the year 1996. How safe is it? bulk of the scientists who have assessed the safety of Wi-Fi networks advocate the fact that there is no particular evidence to the Wi Fi connections being speculative to health. The technology however is non very old. Thus any health hazards that may be decompress would only be evident after a certain number of years. Till then it cannot sure be judged whether a Wi Fi is safe or not. The radio waves that are used by a wireless device or network are relatively small in frequency. The 2.4GHz of radio waves used in the case of Wi-Fi are the non-ionizing type of radiation. This radiation, also used in microwaves and mobile phone communications etc., is not known to have destructive effects on human cells. There is however, one school of thought among scientists that advocates that such a frequency of radiation is harmful to chromosomes. Also, this school of thought thinks that the radiation does not precisely heat up the human atoms but does much more than that. There however is no scientific evidence to prove the above facts. Another school of thought emphasizes that characterization to microwaves and cell phones using low level radiation may scientifically be harmless as yet but the exposures to these waves in the above mentioned devices are relatively for a very short period of time as compared to the exposure to a Wi-Fi router that may be located in your office or home. The spectrum that these low radiation emitting devices secrecy is very large and is constant. The Wi-Fi routers in the vicinity of a human being are turned on twenty four hours a day and seven days a week throughout the year. though no scientific evidence may yet be present but Wi-Fi devices are hazard to me more of a risk than any other devices using the same low level frequency of radio waves.
