Over the years wireless signals have advanced from theoretical observations to a readily applied science that plays a major role in many aspects of modern life. Wireless communication became possible thanks to the discovery of radio waves in 1880, which led to the first demonstration of telegraphic communication in England. In 1901, operators transmitted a short wireless signal between Canada and Britain, the first long distance wireless transmission. Korea launched the world’s first 3G commercial system for widespread use, and it was not until 2009 that the 4G system became widely available. This latest development also established a variety of hardware changes that would help combat 2.4 GHZ crowding, ensuring that more bandwidth became available. Experts speculate on the future developments of wireless networks, and many predict that such systems will continue being made more accessible for all users.
