WIRELESS TECHNOLOGY

Wireless Technology

Introduction

It's no secret that wireless technology has become the standard for strengthening the capacity of communication, entertainment and education across the globe (Nicopolitidis 2003).

History

In 1876, Alexander Graham Bell invented the telephone. By the end of 1889 there were almost 50,000 telephones used in the U.S. only. 19 years later, Italian inventor Guglielmo Marconi sent and received the first radio signal across the English Channel(Firestone 2008).

Neglected optics, which fascinated earlier scholars for more than two thousand years ago, one could argue that the long trail of innovation that led us to the quick, cheap and (mostly) reliable wireless products and services today actually began with Benjamin Franklin and his famous snakes(Nicopolitidis 2003). It is very unlikely that in fact Franklin conducted an experiment, as is so often described, with keys associated with the kite string - he did it, he would never have survived to sign the Declaration of Independence! But Franklin did, in 1747, a model of electricity, which proved to be remarkably correct. At this point, it became apparent that electricity can actually move through the air.

In 1819 Danish physicist Hans Christian Oersted observed that a compass needle will move in an electric field, which will establish the fundamental relationship between electricity and magnetism(Yacoub 2002. We encourage all electromagnetic fields and to this day.

In 1831 Michael Faraday demonstrated electromagnetic induction and built the first DC generator. Although it is not useful for wireless communications, it provides a way to generate electricity.

Electromagnetic field

The next big step forward was the result of the theoretical work of James Clerk Maxwell, the great Scottish physicist. He published "On the Dynamic Theory of Electromagnetic Fields" in 1865, and in 1873, "Treatise on Electricity and Magnetism," which became the so-called Maxwell's equations. This is a series of very complex differential equations describing the motion of electromagnetic waves in space(Ganesh Pahlavan 2000). It is noteworthy that we use them to this day. I'm always amazed that someone working in the cold, damp houses in Scotland, with little in the way of computing technology, and probably no more than an oil lamp for lighting, has developed something so fundamental and powerful that we still use him. Maxwell, incidentally, never saw the radio, they do not exist, and he had no real experience with the radio itself. But he developed a theory paved the way for the next set of critical inventions.

Drawing on the work of Maxwell, Heinrich Hertz in 1887, invented the generator (alternator) and created the waves. Incidentally, this is the Hertz megahertz and gigahertz, not the car rental company(www.microsoft.com). I would also like to mention that the Oersted, Faraday, Maxwell were all physical units of measurement named in their honor as well.Wi-Fi

Wi-Fi, which stands for Wireless Fidelity, in a game is based on the older term Hi-Fi, a wireless network technology used around the world. Wi-Fi refers to any system that uses the 802.11 standard, which was developed by the Institute of Electrical and Electronics Engineers (IEEE) and released in 1997(Ganesh ...
