Wireless Networks

The wireless network provides flexibility and convenience while meeting the communication needs of non-wired devices. Personal Area Networks (PAN), Local Area Networks (LAN), and Wide Area Networks (WAN) are the three general categories into which these networks fall. Different technologies that are suited to particular applications are used in each category. In order to meet personal communication demands like computer-to-printer or computer-to-speaker connections, PAN networks use technologies like Bluetooth, Zigbee, and Near Field Communication. Wi-Fi technology is mostly used in LANs to connect devices in offices or buildings. With the use of technologies like cellular networks, WAN makes it possible for devices located hundreds of kilometers away to communicate with one another. This chapter provides a complete overview of each of these technologies by thoroughly examining their structures, features, access strategies, and other aspects.
