INTRODUCTION
1.1 Background In this technological age, nothing is by all accounts unattainable, because of the astounding achievements in various fields of science and engineering. Day by day, the dependability of humans on technology for daily life chores is increasing enormously. For example, the rapidly increasing popularity of internet, which is an electronic data network, acting as a reliable and efficient medium for providing information, as well as, services over wide range of subjects. In this technological era, the evolution of wireless communication is rapid and it is replacing the wired communication due to its various benefits upon wired communication, such as deployment flexibility, mobility, high productivity, cost effectiveness, feasible long distance communication capability, easy service purveying methods, effortless reconfiguration, feasible installation in remote areas where installation of communication medium is a complex task, more effective in difficult situations like disaster management, emergency conditions, etc [1]. Wireless communication mediums include wireless local area network, cellular, cordless phones etc. are play an important role and have become a necessary part of people’s life. Using equipments like laptops, cell phones, tablets people can access needful information wherever and whenever required and also can communicate with each other. All these type of systems requires a fixed infrastructure. They required high

The difference between these wireless encryption is that WEP is wired equivalent privacy, a default procedure for wired security networks, WPA is an upgrade from WEP, and it is a wireless protected access to networks, whereas WPA2 is modernized into a more secure Wi-Fi from WPA. 2. With Static addressing, a computer (or other device) is configured to always use the same IP address, whereas dynamic addressing, the IP address can change periodically and is managed by a centralized network service.
Illustrate how a mobile station dynamically perform timing advance, adjust power level and perform handover operation 8. Describe advanced digital
• ICMP; is one of the main rules of the internet protocol suite. It is used by system devices, like router, to send error messages showing, for example, that a demanded service is not offered or that a crowd or router could not be touched. • DHCP; Dynamic host configuration protocol is a customer server rules that repeatedly delivers an internet rules (IP) address and other linked arrangement information such as the subnet mask and avoidance entry. • Bluetooth; Bluetooth is a wireless communication technology that lets people to usefully connect their plans with other policies “and “the character of the technology is developing to not only allow devices to talk with one another, but actually allow the all-in-one communication between devices, native requests and the cloud.” •
Wireless technology is used for data transmission. Wireless technology carries a particular information from one place to another. Examples of wireless technologies are a remote control because while you’re using it, it sends control commands information to your TV making you want to change the channel or record a particular programme. Another example of wireless technology is a wireless sound system because it sends audio information to speakers and headphones. Bluetooth is a wireless technology used for the exchanging of data over short distances.
We are now just one click away from buying a car or communicating with someone halfway across the world. “The Internet has revolutionized the computer and communications world like nothing before. ”("Internet Society."). Scientists and engineers like Roberts and Kleinrock worked very hard to put their ideas down on paper to describe this global communication through a network. The first form of the Internet was originally called ARPANET.
This report is connection with the request of The Athlete’s Shack (TAS) sporting goods store to go wireless. TAS has grown in popularity and expanded to 10 more stores in the area and now wishes to implement wireless technology to link all the stores through wireless broadband service. In addition, TAS requested installation of WLANs in each store in order to provide its employees with iPads for better customer service. Consequently, Wireless Technology Company (WTC) that supports businesses with concerns involving network preparation and development has hired me for my expertise.
Wireless service has become an important part of our daily lives. More and more people are texting, posting, streaming, and getting directions to places utilizing wireless services. Crown Castle, as the United State’s main source of wireless infrastructure, has been operating and leasing their infrastructure with wireless providers, public safety organizations, governments, property owners, and M2M businesses since 1994. In today’s society, technology and information access is essential in our daily lives.
This document belongs to the information period of United States history. This period was important to the U.S, because it was the beginning toward people from various parts of the world being able to keep connected with one another. This period in history bought the computer the internet. The internet is what enabled not only different people to stay connected with one another but it also enabled research to be done quicker.
It was used to connect academic institutions and Universities to a large data base. That way they could all exchange data. Video game consoles saw a huge surge in popularity in the 80s. The mother of them all was the Atari 2600. It didn’t get much simpler than two joysticks with big orange buttons Ralph Alessio and Fredrik Olsen received a patent for the Indiglo night light.
Our thought processes, in short, begin to mirror the way a computer processes things in terms of efficiency and data processing. Today, it seems that almost everything is on or reliant upon the Internet. It is “becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV,” Carr says (321). The Internet interconnects everything we do in the media age.
By the 1960s, computers were used for data processing, scientific research, and military operations. The development of the microprocessor led to the creation of smaller, more powerful, and more affordable computers. This enabled the development of personal computers and eventually the internet. The internet had a profound impact on communication, information sharing, and business.
Wireless networks exist everywhere in now day society,
The Internet includes commercial, educational, governmental, and other networks, all of which use the same set of communications protocols.” The Internet has rapidly taken over, not only the United States, but also in numerous other countries across the ocean. “There was an estimate of 3.5 billion
Human population started to growth steadily because people started to use their knowledge to find cure terminal illnesses. All these development change the human understand about life and this understand opened a different path in human history. Furthermore, humanity can access information at the push of a button after the many technological developments such as internet. After the Age of Enlightenment people started to find information freely and this freedom beat a path to find many other information. In 1983 some scientists build a network, which people calls it internet now, to access information all around the world.
There are two main types of broadband connection, a fixed line or its mobile alternative. Both have their strengths and potential weaknesses so you need to consider what suits your needs before you sign up on a lengthy contract. Fixed line broadband is what most people have at home. It 's a fast internet connection delivered by telephone wire (ADSL) or fibre optic cable. As the latter is now capable of speeds in excess of 100Mb, an increasing number of homes have "superfast" fibre optic connections.
