Rapid Growth Of Wireless Communication Information Technology Essay

Rapid Growth Of Wireless Communication instruction Technology EssayIt is our pleasure as a group to convey our lecturer Mr Mohd Hairi Bin Halmi for giving us the opportunity to do this question as it helped us in exploring our potentials in the filed of Communications Networks and has also taught us the various principles involved in the conceive of Wimax Network Architecture.Many give thanks go to the entire group for the time spent in discussing the job and sharing ideas.ABSTRACTThe rapid growth of radio procurer converse and its permeant use in all walks of life be changing the charge we communicate in all fundamental ways. It is one of the most vivacious areas in the communication field today. True Wireless communications earn gained a momentum in the run decade of twentieth atomic number 6 with the success of second Generation (2G) of digital cubicleular roving services. widely distri exclusivelyed successes of Global System for Mobile Communications (GSM), Int erim Standard 95 (IS-95), Personal digital Cellular (PDC) and digital Advanced Mobile squall System (IS-54/136) have enabled pervasive ways of life for the new-fangled cultivation and communication technology era. Second Generation (2G), 2.5G, and Third Generation (3G) standards of mobile systems are being deployed everywhere worldwide.Worldwide Interoperability for Microwave Access (WiMAX) is a standards- ground receiving set technology for providing high-speed, last-mile broadband connectivity to homes and businesses and for mobile wireless electronic networks. WiMAX is similar to Wi-Fi but offers larger bandwidth, stronger encryption, and better performance over longer distances by connecting betwixt receiving stations that are not in the line of sight. Internationally, WiMAX has been finding a home among emerging markets that dont have a decent wired infrastructure.WiMAX is fundamentally a next- multiplication wireless technology that enhances broadband wireless introduc tion. Therefore, it croup be said that WiMAX is a transmutationary wireless technology that, we believe, could change the wireless technology landscape considerably.CONTENTS1. Introduction ..52.

INTRODUCTION1.1 BackgroundThe development of innovative Wireless communication systems has marked the start of the new Era. The transition from fixed to Wireless genuinely started during the Internet r phylogeny. The Internet world evolved as a n exchange mechanism for electronic data, but soon sparked worldwide demand for anytime/anywhere computing and communications. In wireless technology, data is transmitted over the air, and it is an ideal platform for extending the innovation of home networking into the area of mobile devices around the home. Consequently, wireless technology is visualised as a new system that complements phone-line and power-line networking solutionsFrom the late 1970s until today, in that respect have been three generations of wireless systems based on different access technologies 1G wireless systems, based on FDMA (frequency partition multiple access) The first generation of wireless systems was introduced in the late 1970s and early1980s, and was built for voice contagion only. It was an analog, circuit-switchednetwork that was based on FDMA air interface technology. 2G wireless systems, based on TDMA (time division multiple access) and CDMA (code division multiple access) The second generat ion of wireless systems was introduced in the late 1980s and early nineties with the objective of improve transmission quality, system capacity, and range. Major multiple-access technologies use in 2G systems are TDMA and CDMA. These systems are digital, and they use circuit-switched networks. 3G wireless systems, mostly based on W-CDMA (wideband code division multiple access)The 3G wireless systems are digital systems based on packet-switched network technology intended for wireless transmission of voice, data, images, audio, and video. This started in the mid 1990s and is ongoing developments until today. The various gyrationary developments seen during this phase are the UMTS, the CDMA2000. This phase of revolution is ongoing till today where we can see various new wireless technology innovations such as the Wi-Fi, WiMax, etc.The entire evolution and progress of all these 3 generations of wireless systems has led to the internet revolution that we enjoy today. Today, we live i n a world where communication has evolved into a landscape that a person in 1990 would scarcely recognize. TALK A LIL MORE ON HOW WIMAX EVOLVED-introdn commands 2 include more abt wimax accord to WiMAX forum Wimax Technology is a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to line of reasoning and DSL. Wimax Technology will provide fixed, nomadic, movable, and, eventually, mobile wireless broadband connectivity without the need for direct line-of-sight to a base station. In a typical cell radius deployment of 3 to 10 kilometres, Wimax Forum Certified systems can be expected to deliver capacity of up to 40 Mbps per channel, for fixed and portable access applications.WiMAX has the potential to provide widespread Internet access that can usher in economic growth, better education and health care, and improved entertainment services. WiMAX can be described as a exemplar for the evolution of wireless broadband rather than a static implementation of wireless technologies. Therefore, in this era, we can consider WIMAX as a wireless technology revolution.1.2 PURPOSEObjective Through this report, our main objective is to study the WiMAX Network Architecture and the evolution of WIMAX in the internet industry as a wireless technology revolution.1.3 SCOPEOur report covers all the principal(prenominal) aspects of the network architecture of WiMAX. We mainly focussed on the practical uses of WiMAX in the world of internet hence making our scope limited to this. We used various resources for this research from internet to books to journals.2.
