Wireless Networks :: Networks Telecommunications

intercommunicate service symbolizes a development of engine room, and perhaps a new eon of telecommunications, but these services discombobulate been used for over a atomic flesh 6 and remain identical with the radio. The modest beginning of tuner services takes us back to the 19th century at time when Guglielmo Marconi, the perplex of radio made his mark in the world of radio set technology. When Marconi started experimenting with radio waves (Hertzian Waves) in 1894 his idea was to produce and detect radio waves over longsighted distances. In 1896, Marconi was successful and obtained a patent and established the radio telegraphy and Signal Company Limited, the first radio factory in the world. In 1901, signals were received across the Atlantic and in 1905 the first wireless regret signal was sent use Morse Code. Wireless technology in the end progressed as an invaluable tool used by the U.S. Military. The Military piece wireless signals to transmit data over a mediu m that had abstruse encryption, which makes unauthorized access to network traffic almost impossible. This type of technology was first introduced during World War II when the Army began sending booking plans over enemy lines and when Navy ships instructed their fleets from shore to shore. Wireless proved so important as a secure communications medium some melodic linees and schools thought it could expand their computing arena by expanding their wired local anesthetic landing field networks (LAN) using wireless LANs. The first wireless LAN came unneurotic in 1971 when networking technologies met radio communications at the University of Hawaii as a research project called ALOHNET. The bi-directional star topology of the system included sevensome computers 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 passage into every house, classroom, and business arou nd the world.Wireless network technology has been implemented for a number of things including cell 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. Personal 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.
