Wireless data has become the technology of the future. Data is being passed from one location to another without the human eye detecting this transaction. Wireless data is transferred in many forms from home networks, business networks, and cellular networks. Each of these networks operates on a different scale and technology.
Home networks have been steadily growing over the years as manufacturers have developed new and easier to use devices that install quickly and give the owner the ability to manage their own wireless internet at home. Wireless routers have become the standard at home and many users are installing these to allow the growing number of computers and laptops in their household to access the World Wide Web. Wireless routers use high-frequency radio waves to transmit data across the home network to a laptop or desktop wireless network card. First, the computer uses the wireless network card, also known as a wireless adapter, to translate the data into radio signals then broadcasts the signal using the built in antenna. The wireless router receives the signal, decodes the information, then sends the request of information to the World Wide Web through the router’s own wired connection to the Internet Service Provider (ISP.)
These routers currently transmit in the frequency range of 2.4 GHz or 5 GHz allowing the signal to carry more data than other lower frequency devices such as cell phones, walkie-talkies, and televisions. (Brain and Wilson) Currently, wireless routers operate in the 802.11 standard as established by the Institute of Electrical and Electronic Engineers of which it has four commonly used versions: 802.11a, 802.11b, 802.11g, and 802.11n. Each of these standards allow for different data connection rates and distances achieved from the router to access the signal. For example, 802.11g offers up to 54Mbps and uses the 2.4 GHz frequency to transmit and deliver its data. It also allows for backwards compatibility with the 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters. (Mitchell) On the other hand, 802.11n offers up to 100Mbps with an increased signal range and, like 802.11g, is backwards compatible. Home networks are commonplace in today’s society, but wireless networks in business have been around for years as companies tackled the challenges of connectivity in large offices and multiple locations.
Most businesses today use wireless technologies in one form or another. They use wireless access points to deliver the network to the local building for laptops and other devices. They also have the ability to connect sensors that monitor heat/cooling, door access, and cameras. One form of wireless technology implemented by businesses is the use of a wireless controller for connecting multiple access points to create a Wireless Local Area Network (WLAN.) This is accomplished by configuring the wireless controller with the necessary information such as Service Set...
