Principles of Wireless Networks - Essay Example

The electromagnetic energy involved in communication is the microwave-high frequency radio waves that are transmitted from the source to the receiver through the radio transmitter. Information is transmitted from the source to the receiver through transforming energy from one state to another. When using any communication device, the sound waves generated lead to vibration of the diaphragm in a magnetic field. The vibrations are then changed into electrical impulses that are conveyed through a wire to the receiver.

In the receiver, the impulses cause the magnetic fields to vary causing vibration of the diaphragm. The diaphragm then produces sound similar to the original (Caloz & Itoh, 2005). The flow of the energy in communication is presented in the chart below. One of the main differences between wired and wireless communication is that whereas wired communication uses cables in connection, the wires communication do not use any form of connection via cables but rather uses radio waves. Wireless communication, the internet, and smartphone technology are major breakthroughs in the process of communication.

These technologies have not only facilitated the link between one individual to another but also it has improved the link between world economies. It is now very possible to acquire property at the comfort of our homes. This has lead to immense growth in the world economy (Pahlavan, 2011). In my day to day life, I often use wireless communication, the internet and the smartphone in passing my information to other people. The underlying scientific concepts used in this technology transmission of electromagnetic waves from the source to the receiver.

The wireless and wired network options have to lead to the current growth in the communication infrastructure. With the current growth in these options, communication in society will be a lot easier and cheaper in the future as compared to the current state.
