Wireless networks are designed for all home and business networking applications and are used in both local area networks (LANs) and wide area networks (WANs). In Chapters 2, 3, and 4, we reviewed some fundamentals of wireless communication media at the link layer and at the LAN scale. In this chapter, we explore the concept of wireless networks at the WAN scale. The main topics of the chapter are:
• Infrastructure of wireless networks
• Cellular networks
• Mobile IP management in cellular networks
• Long-Term Evolution (LTE) technology
• Wireless mesh networks (WMNs) with LTE
• Characterization of wireless channels
We start with an overview of wireless communication systems at all levels, ...
