Wireless Networks
We are witnessing a paradigm shift in communication technology and wireless communication is fast becoming the growing trend. Wireless LANs offer an entirely new level of service which cannot be supported by conventional wired communication and thereby extend the usefulness and performance of technology. Wireless networks have considerably influenced our day today life. The new applications of Wireless networks have drastically improved our connectivity from a limited to an ever-expanding world of information. The birth of cellular technology, infrared and spread spectrum radio services have revolutionized our world of communication. The continuous progress in Wireless technology has made the dream of a mobile workforce already a reality.

Wireless networks imply a wide array of technology that offer different services and operate in different ways. Wireless networks use air as the communication medium and eliminate the system tethers and the associated difficulties. Unlike the wired medium of communication, in a wireless….

To get a sense of how effective these metropolitan WiMAX networks are, it's useful to look at a WiMAX Scenario Analysis, which is shown in Figure 1. This schematic diagram shows how the various clients for a system would interact with base stations as subscribers, followed in transmission, aggregation and multi-service core aggregation of messaging. Figure 1 illustrates best practices in creating a WiMAX network across a broad metropolitan area.

Wireless ervice Providers
In the United tates there are currently more than 40 wireless service providers. Many are local while others such as Alltel and Cricket have strategies to expand farther their current networks in the Northeast, outheast and West. In looking at the competition and trends, it is likely that the large players in the industry will either acquire smaller companies or that the companies that dominate the market will simply put smaller companies out of business.

The current top-four players in the industry are Cingular, Verizon, AT& T, and print PC.

Verizon Wireless tops the list of wireless providers, serving 33.3 million customers. It covers 49 of the top-50 wireless. markets and 97 of the top-100 markets and 97 of the top 100 markets. The company's network sales and infrastructure includes 1,200 company stores and 140 switching stations (Verizon 2002 Annual Report 2).

Cingular takes second place, serving 22 million customers in….

Free ireless Networks
Since the construction of the information Superhighway, its' use to distribute information has become phenomenal. Information gathering and dissemination is the most valuable asset for a business to succeed. Demands for more and more efficient means of connecting to the Internet have driven exponential technological advances. So much so that the craze to connect has gone wireless and with this technology an entirely new set of issues, concerns and problems have arisen. One movement associated with the wireless phenomena is the free wireless internet access movement, not unlike the original free internet movement, which largely became a victim of cost burdens and an inability to increase technology with growth, the free wireless movement is a demand by individuals and communities to offer a network or global (inside city limits) connectivity system that is free of charge to the wireless user.

This paper will define and analyze the free wireless….

Wireless Networking Phenomenon
Today's world is faced with a myriad of challenging and complex issues that require advanced technological solutions. As technology becomes increasingly user-friendly and focused on the consumer, it is evident that users have become more dependent on wireless technological devices as mechanisms that promote convenience, survival, and economic prosperity. Devices such as cellular phones, laptop computers, and personal digital assistants have become absolute essential components for many consumers for personal usage as well as for businesses in order to increase communication access at all times and locations. Wireless technology has essentially replaced face-to-face communications to some degree and has dramatically improved the economic and communicative expectations of its users across the globe.

METHOD

This study will demonstrate the absolute importance of personal and business forms of wireless technology in today's increasingly complex society. Various books, periodicals and research journal articles will summarize the history of communications leading up to the….

luetooth devices use encryption security and this makes the requirement of a "unique key session key to derive per-packet keys thus avoiding frequent key reuse." (Kennedy and Hunt, 2008, p.4)
Kennedy and Hunt report that Zigee is a reasonably priced low energy consumption two-way CDMA/A-based wireless communications standard which is based on IEEE 802.15.4 which is referred to commonly as a 'Low Rate Wireless Personal Area Networks (LR-WPANs) and which is targeted primarily "at radio frequency applications requiring low data rate, long battery life and secure networking." (p.4)

LP-WANS "offer device level wireless connectivity..." And as well "they enable a range of new applications as well as enhance existing applications." (2008, p.4) These devices are low in cost and low in their energy use and due to their self-organization features are useful for public security applications as well as for tracking inventory and automation in the home and office. A wireless….

As one expert notes, "Access to patient information by healthcare professionals at the point of patient care is critical to improving patient safety. Physicians and nurses move between patients reviewing, documenting and delivering care" (Author not Available, 2007, p. 2). Using wireless technology helps improve productivity, because doctors and nurses do not have to return to a fixed computer, and they can use other devices right away. Ultimately, this reduces costs and time spent between patients, and improves the quality and effectiveness of care.

Wireless technology reduces costs because it allows personnel to be more efficient. It also reduces the need for some staff, like medical records, as these records ultimately are input into the computers. Other areas of healthcare, such as asset management, also benefit from wireless technology, as high-cost assets can be monitored electronically to reduce theft and vandalism (Author not Available, 2007, p. 3).

Using wireless technology can drastically….

Wireless Local Area Networks
The establishment of home and business networks desirous of upgrading to Wireless Local Area Network- WLAN confront with the problems of choosing from available alternatives. The vendors offer several products for sale that hovers around different wireless standards like 802.11a, 802.11b, 802.11g and Bluetooth. During the year 1997, the Institute of Electrical and Electronics Engineers -- IEEE developed the first WLAN standard. They termed it 802.11 in line with the name given to the group appointed for supervising its development. However, to our misfortune the 802.11 could support only a maximum bandwidth of 2 Mbps -- too slow for most applications. Due to these ordinary 802.11 wireless products could not be manufactured further. (802.11 Standards - 802.11b 802.11a 802.11g: Which one is right for You?)

The IEEE standard is an extension of the original 802.11 standard devised during July, 1999 generating 802.11b specification. While 802.11b was devised the….

Network/IT Communications
Selecting the type of cable to be used when developing a LAN from the ground up can be a complex process with many considerations, including issues of functionality and of cost. Twisted pair cables provide a cheaper alternative to other cable types and are also the most flexible type of cable, but they are less secure and are more prone to losses in data integrity than are other standard cable types (Hsieh, 2012). Fiber optic cables provide the best protection against interference and are the most secure cable for use in a network, but the cost can be prohibitive and the heightened performance aspects are not necessary in all applications (Hsieh, 2012). Coaxial cables come in two varieties, thinnet and thicknet, with thinnet being both cheaper and more flexible than twisted pair cables (though still more expensive and less flexible) and also provide a decent amount of security and….
