Appendix: Key Features of Major Wireless Network Types
Since the Internet era began some two decades ago, communication networks have been expanded to cover virtually every part of the world, reaching remote areas by wireless links. Wireless communication technology evolved over a century ago from the Maxwell equations that describe the fundamentals of electricity and magnetism (Huray, 2009):
Electric Field (E):
Magnetic Field (H):
With interrelationship:
Figure A.1 Network classification based on coverage
We shall not go through the mathematical details but what we are interested in knowing is the fact that the above Figure A.1 shows what forms the basic blocks of wireless communications utilizing the relationships between electric and magnetic fields. Technical advances throughout the twentieth century have made many wireless transmission networks possible for an endless range of applications.
In the post-war era, television broadcast was probably one of the most popular wireless communication systems which is now used by billions of people throughout the world. While traditional ...
