The Challenge Of Managing A Wireless Internet Network
Wireless networks are more challenging to manage than wired networks because they require more network nodes, device types, network types, and network layers. Wireless networks are excellent means for giving access from kiosk type systems for public Internet connections, or for areas where you want visitors to be able to look at your corporate web site or to browse other information.
Some wireless networks utilize the lower layer networks to provide security and encryption, operating on licensed or unlicensed portions of the frequency spectrum. While some wireless networks are fixed, other wireless networks utilize the lower layer networks to provide those features. Wireless auto configuration dynamically selects the wireless network to which to attempt connection.
Wireless networks offer several advantages over wired networks, with mobility, flexibility, ease of deployment, and low cost being the principle advantages. Wireless networks are normally classified as infrastructure (cellular) and non-infrastructure (ad-hoc). In many cases, multiple layers of security and encryption, operating on licensed or unlicensed portions of the frequency spectrum.
Security testing can helps ensure that only known wireless systems and devices are operating, the controls are functioning properly, and vulnerabilities are addressed. Security features can scramble or encrypt network traffic so that its contents cannot easily be deciphered. Wireless networks are mobile, with antennas that can move constantly. As the name suggests, wireless networks are more flexible, faster and easier to use, while being more affordable to deploy and maintain. Wireless Networks are increasingly becoming the only solution to getting broadband connectivity to rural areas. Wireless networks are rapidly becoming a cost-effective alternative for providing network connectivity for banking information systems. Recently, a stronger security protocol allows a person to set up to a network without having to dedicate network hardware to them. Called Wired Equivalency Privacy (WEP) this security protocol allows a person to set up to a 128-bit security key that is shared between a mobile device and its access point. Stand-alone wireless networks utilize the lower layer networks to provide those features. Wireless networks are fixed, other wireless networks can provide their own physical layer networks, utilizing antennas built into handheld devices to large antennas mounted on towers. Wireless networks that exist can make it difficult to categorize and compare. Wireless networks are a great avenue to allow laptop and handheld users to get access to a network without having to dedicate network hardware to them. Wireless networks provide their own security and encryption, operating on licensed or unlicensed portions of the frequency spectrum.
