Internet Networks: Wired, Wireless, and Optical Technologies (Devices, Circuits, and Systems) (English Edition) 1第一 版本, Kindle电子书
In the not too distant future, internet access will be dominated by wireless networks. With that, wireless edge using optical core next-generation networks will become as ubiquitous as traditional telephone networks. This means that telecom engineers, chip designers, and engineering students must prepare to meet the challenges and opportunities that the development and deployment of these technologies will bring.
Bringing together cutting-edge coverage of wireless and optical networks in a single volume, Internet Networks Wired, Wireless, and Optical Technologies provides a concise yet complete introduction to these dynamic technologies. Filled with case studies, illustrations, and practical examples from industry, the text explains how wireless, wireline, and optical networks work together. It also:
- Covers WLAN, WPAN, wireless access, 3G/4G cellular, RF transmission
- Details optical networks involving long-haul and metropolitan networks, optical fiber, photonic devices, and VLSI chips
- Provides clear instruction on the application of wireless and optical networks
Taking into account recent advances in storage, processing, sensors, displays, statistical data analyses, and autonomic systems, this reference provides forward thinking engineers and students with a realistic vision of how the continued evolution of the technologies that touch wireless communication will soon reshape markets and business models around the world.

Sadly, one chapter is marred by an elementary physics mistake. It discusses satellite communications, and has a Figure 7.1 showing a satellite orbiting the Earth. A centripetal force is shown, and so too is a centrifugal force. The accompanying text says correctly that the centripetal force is due to the Earth's gravity. But then it goes on to assert that the centrifugal force is "due to the circular (more specifically elliptical) motion". Wrong. In an inertial reference frame, there is no centrifugal force on the satellite. There is only one net force acting on it, the centripetal force. The satellite is not in equilibrium, so it is not moving in a straight line. This is one of Newton's laws. The very fact that it is moving in an ellipse means that it is acted upon by a net force.
Another way of looking at it is to consider that if the centrifugal force exists, what object is causing this? From this standpoint, you can see that the above quote about the centrifugal force is rubbish.
