Wireless Networks :: Networks Telecommunications

radio set services symbolizes a development of technology, and perhaps a new era of telecommunications, but these services have been used for all over a century and remain identical with the tuner. The modest set about of wireless services takes us back to the 19th century at time when Guglielmo Marconi, the father of radio made his mark in the public of wireless technology. When Marconi started experimenting with radio waves (Hertzian Waves) in 1894 his idea was to produce and detect radio waves over long distances. In 1896, Marconi was successful and obtained a patent and naturalized the receiving set Telegraph and Signal Company Limited, the commencement radio factory in the world. In 1901, signals were received across the Atlantic and in 1905 the first wireless distress signal was sent using Morse Code. Wireless technology ultimately progressed as an invaluable tool used by the U.S. Military. The Military configured wireless signals to transmit data over a medium that h ad complex encryption, which makes unauthorized access to network traffic around impossible. This type of technology was first introduced during World War II when the regular army began sending battle plans over enemy lines and when Navy ships instructed their fleets from shore to shore. Wireless proved so important as a secure communications medium many businesses and schools thought it could expand their computing arena by expanding their wired local field of battle networks (LAN) using wireless LANs. The first wireless LAN came together in 1971 when networking technologies met radio communications at the University of how-do-you-do as a research project called ALOHNET. The bi-directional star topology of the arrangement included seven calculating machines deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. And so, wireless technology, as we know it, began its handing over into every house, classroom, and busines s around the world.Wireless network technology has been use for a number of things including carrell phones, PDAs, and personal and business computers. There are three types of wireless networks, wide area networks (WAN), wireless local area networks (WLAN), and personal area networks (PAN). Wide area networks include the networks provided by the cell phone carriers. Wireless local area networks are networks set up to provide wireless connectivity within a certain coverage area. person-to-person area networks are networks that provide wireless connectivity over distances of up to 10m or so.Wireless networks have many advantages, but also has many disadvantages to.
