Wireless Technology

The idea of wireless data is far not new. In 1901, Guglielmo Marconi established telegraph communication between the ship and the coast. Nowadays digital wireless technologies are more powerful; but they are based on same idea. The changes that happened in wireless technology for the last five years and the future of this technology are discussed in this paper.

“Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path” (Wireless technology explained with examples, n. d.). Everyone knows about Wi-Fi and almost everyone uses Wi-Fi every day. Until 2010, for the exchange of data using the Wi-Fi between devices one had to use the access point. Development of new standard of wireless communication, such as Wi-Fi Direct, accelerated use of virtually all devices for data exchange. Thus, “mobile phones, cameras, printers, PCs, and gaming devices can now connect to each other directly to transfer content and share applications quickly and easily” (Wi-Fi Alliance and Wakefield Research, 2010). Use of this standard made it possible to connect different devices to each other without an access point. Additionally, Wi-Fi Direct can be used for all kinds of applications in any device (Wi-Fi Alliance and Wakefield Research, 2010). The connection between devices is performed directly without intermediate link. This has greatly simplified the process of exchanging data as everything can be wirelessly connected (Coughlin, Johnson & Lo, 2012).

Major breakthrough in wireless technology in the next five years will be the use of visible light for the data transfer. Many organizations, such as Casio, Toshiba, and Samsung etc., are engaged in researching in this area. Use of the light emitting diodes in the wireless data transfer systems will possibly lead data transfer to the new level of speed. The basic principle of using the visible light for the data transfer lies in the imposition of information on the flow of visible light by modulation. Although, according to Wood (2013), visible light communication technology is still in the introductory phase, it is going to be one of the greatest changes and achievements in future it will. Also, the use of visible light communication technology would help to decide a number of technological problems (Jamieson, n. d.).

The evolution of the wireless technologies is one of the ways to get the very high speed of data transfer. The wires are disappearing. Maybe one day, people will become little parts of the biological data network with very high speed of data exchange. Perhaps, the use of visible light soon will become commonplace like use Wi-Fi today. Thus, an ordinary light bulb might be a source of information in future due to the development in wireless technologies.
