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.

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.

Exploring the Basics of Wireless Local Area Networks
Introduction

In today's digital age, connectivity plays a crucial role in how we communicate and interact with the world around us. One of the technologies that enable this connectivity is Wireless Local Area Networks, commonly known as WLAN or Wi-Fi.

A Wireless Local Area Network is a type of network that allows devices to connect and communicate wirelessly within a limited area, such as a home, office, or campus. This technology has become essential in our daily lives, as it allows us to access the internet, share files, and connect with other devices without the need for physical cables.

Wireless Local Area Networks operate using radio waves to transmit data between devices, such as computers, smartphones, and tablets, and a central access point, known as a Wi-Fi router. This access point serves as the bridge between the devices and the internet, providing a seamless connection for…...

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).

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…...

Conclusion

The purpose of this discussion was to examine the network security measures that are available. The research found that the proper configuration provides the first line of defense as it relates to securing a network.

In addition, firewalls serve an essential role in securing networks against outside intrusions. The research also indicates that anti-virus software, encryption software and biometrics allow organizations to secure networks in a more comprehensive manner. There are also specific strategies and technologies that should be considered if an organization chooses to use a wireless network.
