Wireless Area Networks Essay -- Technology Technological Essays

Wireless Area Networks Wireless technology has run low an increasingly crucial part of right aways world. From health care and retail to academia across the world, tuner systems are improving the rate and ease with which information is sent and received. Two specific examples of the wireless technology used immediately personally and professionally are local battlefield networks (LAN) and personal heavens networks ( move). A wireless local area network, or LAN is a flexible selective information communications system implemented as an augmentation to, or an alternative for a, wired local area network. These networks rely on electromagnetic airwaves to transmit and receive over a defined area, usually a few hundred feet. ( yahoo-wireless) In most cases, a wireless transmitter will be connected directly to a wired destroy network using Ethernet c fittings. Once the network feed has been connected to the transmitter, and a constant power supply is established, a steady stream of radio, or infrared radiation frequency waves with be produced (both are electromagnetic waves). The vast majority of wireless LAN systems tend to rely on radio waves as the carries for their signals, because infrared waves tend to have a shorter distance at which they are subject to transmit, and are more easily interrupted. Radio waves, or radio carriers as they are referred to, transfer selective information through modulations of the carrier signal. The addition of data to a radio carrier causes the signal to occupy more than a single frequency. Once data is imprinted onto the radio signal it is a open reversal of the transmitting process that allows the information to be decoded by a receiving station.

Whether or not wireless systems are practical or necessary in a given situation is a outcome of personal opinion. However, one cannot dispute the success these systems have had in legion(predicate) professional and personal areas and it is very likely that usage of LAN and scrap wireless systems will increase dramatically in the near proximo as technology continues to advance and evolve.
