One of the first items to clear up about this topic is when talking about wireless communications we are just not talking about wireless computers networks. Wireless communications also covers wireless phone networks as well as our wireless computer networks. While writing this paper I will try to keep it on just the wireless computer networks, but you will have to keep in mind that this all was started with the telephone and branched out toward computers and other handheld devices. Me like everyone else probably had never really look at wireless as a very vast network which started in 1876 when the phone was invented by Alexander Graham. In 1877, Charles Williams of Somerville Ma had the first private telephone was installed in the home. Four years later over 47,850 telephones were in use in the U.S. (Fowler, 2009). This was the start of the evolution of Wi-Fi, Guglielmo Marconi, an Italian inventor took it a step closer nine years later, and he proved the feasibility of radio communications by sending and receiving the first radio signal. Then in 1869, the first wireless signal across the English Channel was flasher by Marconi. (Fowler, 2009) This should not be confused with the Birth of Telecommunication as some people have linked Telecommunication with wireless communications as John M Shea, an associate Professor of electrical and Computer Engineering from the University of Florida did in an article were he stated in “The History of Wireless Communications” that The first telegraph? Perhaps drum communication [wikipedia] or signal torches, such as those used for communication in ancient Greece [mlahanas.de] as early as 1100s BC? (Shea, 2011) First of all it was not a good source and I he did leave out the invention of the telephone. So now you want to ask why go wireless? The advantage and Disadvantages speak for themselves!
