As times change, the conventional ways of setting up a network has become more or less tedious. The fact is that with the expanse of communications and telecommunications making the world a very small place, it is impossible to connect any two or more global networks via cables only. The global village of which we are all residents now demands the use of wireless networking protocols and systems. As such, wireless communications have literally taken over every aspect of how we keep in touch. Almost everything we do today depends on some form of wireless interaction.

Let us look at the whole picture logically. If you wish to speak via web cam to a friend in another country, at some point during the whole process some wireless device plays a role. So, if you are in the United States and have a friend in the North Pole, it is very easy to talk to that person (audio and video). The simple process goes like this:

^ You are connected to the internet via your ISP, whether dial up or broadband (can be hard wired or wireless connection)
^ The ISP is connected to either their own VSAT (Very Small Aperture Terminal) or uses the service of a phone company or other private entity
^ The VSAT points into space at a communications satellite with which it exchanges data and information (this is wireless, of course)
^ The communications satellite is linked to an earth station that also sends and receives information between itself and the satellite
^ The earth station sends its data to Central Stations of telephone companies which in turn connect the computers on the network to the person you wish to speak to

Pretty cool, huh?! Wireless networking is indeed here to stay and as time goes by it gets more and more sophisticated. The quality of the transmitted media is also getting better and better and we can expect to see some fantastic changes in media and communications.
