Technology keeps on changing. Decades ago there were no support for technology and due to the lack of infrastructure many technology laggex behind. Many times people had strong belief on their thoughts and cultures. They were not ready to accept or were no ready to implement the technologies back then, but today everything has changed. Today without technology all work seems incomplete.
As the time went on there were more and new inventions that took place. As result there were a lot of changes in existing technology. Among that one major change is wireless technology.
Wire, an important part of any electronic device, transmits power as well as data too. Have you ever thought that there will be a technology that is wireless. Yes today this wireless technology is ruling the world. In the most basic sense, wireless refers to communications sent without wires or cables. However, the term may refer to a broad range of technologies and mediums, from cellular networks to Bluetooth devices to local Wi-Fi networks.
Wireless is a broad term encompassing all sorts of technologies and devices that transmit data over the air rather than over wires, including cellular communications, networking between computers with wireless adapters, and wireless computer accessories. Wireless communications travel over the air via electromagnetic waves.
Cordless phones are wireless devices, as are TV remote controls, radios, and GPS systems. Other wireless devices include phones, tablets, Bluetooth mice and keyboards, wireless routers, and most devices that don’t use wires to transmit information.
The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications.
The term wireless has been used twice in communications history, with slightly different meanings. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. Radio sets in the UK and the English-speaking world that were not portable continued to be referred to as wireless sets into the 1960s. The term wireless was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires. This became its primary usage in the 2000s, due to the advent of technologies such as mobile broadband, Wi-Fi, and Bluetooth. Wireless operations permit services, such as mobile and interplanetary communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems.
The first wireless telephone conversation occurred in 1880 when Alexander Graham Bell and Charles Sumner Tainter invented the photophone, the telephone that sent audio over a beam of light. The photophone required sunlight to operate, and a clear line of sight between the transmitter and receiver.
In 1894, Guglielmo Marconi began developing a wireless telegraph system using radio waves, which had been known about since proof of their existence in 1888 but discounted as a communication format since they seemed, at the time, to be a short-range phenomenon.
The wireless revolution began in the 1990s, with the advent of digital wireless networks leading to a social revolution, and a paradigm shift from wired to wireless technology.
Today, wireless technology encompasses such diverse communication devices as garage-door openers, baby monitors, walkie-talkies, and cellular telephones, as well as transmission systems such as point-to-point microwave links, wireless Internet service, and satellite communications.
