"Wireless communication was developed while wired communication was being expanded. Guilermo Marconi was one of the first to experiment with other ways to communicate besides a wired system. According to the book Marconi used Einstein's theory of relativity to create a system of wireless telegraphy. The book goes on to say that the early development of wireless communications was the stepping stone for today's wireless communications networks. (Regli) In the past wireless networks were unreliable and expensive. The old system was often criticized for not being fast enough and not providing users with the benefits associated with the traditional wired systems. However, today there have been many technological advances that have allowed these networks to become more efficient."

Abstract
Wireless communications and networks very possibly represent one of the greatest technical innovations of the twentieth century. The effect that this kind of technology is having on the development of Western society at the dawn of the twenty first society is truly fantastic, especially for those who can still remember a time before wireless networks and technology, or at least a time when they were much more a novelty than a way of life. This paper shows how wireless networks quite literally have integrated themselves with many aspects of society from work to play to communications. The paper examines some of the basic history of wireless networks, the simpler-than-it-sounds operation of these networks, and some of the applications that these networks have to offer.

Abstract
The nature of communication and social interaction has undergone a substantial change in the past 20 years-and the change is not over. More and more, technology has facilitated social interaction. More recently, the usage of computer networks has indeed represented the biggest change in the nature of social interaction as they have become yet another option to keep in touch with people, both close and far away. Computer networks have in fact changed the nature of social interaction; from trust issues to anonymity, from reduced communication costs and the ability to keep in touch with people who are geographically thousands of kilometers away from home to de-personalization and sometimes isolation.

Using computer networks for social purposes: how it changes the nature of social interaction A social network consists of all the people - friends, family and others - with whom one shares a social relationship. On a macro level, a social network demonstrates how a large group of people are connected to one another (as cited in Golder, Scott, Wilkinson, Dennis and Huberman, Bernardo (2007), page 2). The nature of communication and social interaction has undergone a substantial change in the past 20 years--and the change is not over. More and more, technology has facilitated social interaction.

"At present there are a range of protocols in use for wireless technology. Perhaps the most common is 802.11b. It is moderately cheap in using equipment 802.11b. The free 2.4 Ghz is the frequency range in which 802.11b wireless communication standard works. But there are many systems like cordless phones and baby monitors which obstruct the wireless traffic. For 802.11b communications, the maximum speed is 11 mbps. The new 802.11g standard is an improved version of 802.11b. Though it uses the same busy 2.4 Ghz shared by other common household wireless devices, 802.11g is competent of transmission speeds up to 54 mbps. The equipment intended for 802.11g communicates with 802.11b equipment, but combination of two standards is not suggested. (Quick Tip: Wireless Networking Protocols)"

Abstract
This paper considers how the widespread use of computer networks might contribute to social separation rather than community, though the idea that this could just be a new community is also noted. It looks at how, as these technologies are used more widely, fears grow that people are not communicating directly as they once did and that this technology keeps people apart rather than bringing them together. It also examines how there is an opposing view, holding that this technology allows for more immediate communication in real time and so creates a new sense of community, a community online.

From the Paper
"Many social critics believe that the widespread use of the Internet and other computer networks is having a detrimental effect on human social interaction, reducing the power of community and separating people rather than bringing them together. They see the unity of both the family and the community as threatened by electronic communications, meaning e-mails, chat rooms, websites, and the like. As these technologies are used more widely, fears grow that people are not communicating directly as they once did and that this technology keeps people apart rather than bringing them together. There is an opposing view, of course, holding that this technology allows for more immediate communication in real time and so creates a new sense of community, a community online."

Abstract
This paper discusses how the computer has contributed to the development of new online ocial networks online, which have replaced some systems and supplemented others. In particular, the paper examines the impact of Facebook. The paper then traces how these social networks first developed from the early use of message boards and then extended to the Web with blog sites and other forms of communication.

"The computer has contributed to the development of new social networks online, replacing some systems and supplementing others. Though the computer seems to be a technology that isolates the user at home typing on a screen rather than interacting with people in face-to-face, in truth this technology also allows for more immediate communication in real time and so creates a new sense of community, a community that exists online. A number of online social networks have been created, notably Facebook and My Space, both quite popular and with millions of users each. The idea of online social networks first developed from the early use of message..."

Abstract
The internet has allowed much in the way of increased freedom for information collection and exchange. As a public medium of communication, transactions conducted over the internet are often subject to the scrutiny of unauthorized individuals. The paper explains that the ease with which the internet is utilized has forced the issue of secure communication and secure transaction down to the smaller size enterprise. Unfortunately, to obtain the same level of security brings with it a high cost of investment and continued ownership. The Virtual Private Network (VPN) has changed all of this. VPNs are able to connect remote users and remote LANs into functional networks. This paper describes the VPN in terms of what it is, how it functions, the protocols utilized and its future direction.

"More specifically, two architectures exist for setting up a tunnel. They are client-initiated and client-transparent. The client-initiated tunnel requires tunneling software reside both at the client end as well as on the associated gateways, although the software could reside as well at the ISP POP that serves as the central site. Client software initiates the tunnel and the gateway-resident software terminates the tunnel. In this scenario, the ISP would not have to support the tunneling and the client and tunnel server establish the tunnel using authentication that is based upon a user ID and password. Similarly, the tunnel server and client can also negotiate an encryption sequence. Regardless, once the tunnel is set up, the communication proceeds as if the ISP were absent."

"I believe that it is not unreasonable to hold corporations to the same, if not a greater, responsibility toward the rest of society. The actions of corporations can affect, quite literally, millions of people. We only need to look at the Nestle Infant Milk Formula controversy for an especially distasteful example. Here, Nestle used misleading marketing to sell artificial infant formula to third-world children, resulting in the death of millions of these babies. See Dobbing (1988) for a detailed description of this case. Closer to home, the recent Enron scandal is another example how the actions of a corporation can damage millions of lives."

Abstract
The paper examines the General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology. The paper also discusses the approaching transition to third-generation (3G) networks, which are the third generation of mobile phone standards and technology, superseding 2.5G. 3G is based on the International Telecommunication Union (ITU) family of standards under the IMT-2000, the paper explains, and enables network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. The paper notes that 3G services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. The paper concludes that 3G mobile communications systems are capable of bringing high-quality mobile multimedia services to a mass market.

From the Paper
"One of the major new third-generation (3G) mobile systems being developed within the global IMT-2000 framework is the Universal Mobile Telecommunications System (UMTS), which has been standardized by the European Telecommunications Standards Institute (ETSI). UMTS makes use of UMTS Terrestrial Radio Access (UTRA) as the basis for a global terrestrial radio access network. Europe and Japan are implementing UTRA in the paired bands 1920-1980 MHz and 2110-2170 MHz. Europe also has decided to implement UTRA in the unpaired bands 1900-1920 MHz and 2010-2025 MHz. UMTS combines key elements of Time Division Multiple Access (TDMA)--about 80 percent of today's digital mobile market is TDMA-based--and Code Division Multiple Access (CDMA) technologies with an integrated satellite component to deliver wideband multimedia capabilities over mobile communications networks."
