Recent advances in wireless sensor networks (WSN) and wireless localization have enabled their applications in a range of systems from autonomous collision avoidance to multirobot collaboration in support of search and rescue operations. This chapter reviews concepts and models of wireless channels that are critical to the localization systems. It discusses the general concept of the impact of channel modeling on the design of radio systems. In addition, the chapter investigates important channel parameters for different localization techniques such as received signal strength (RSS). It also discusses channel parameters essential to position location methods such as time of arrival (TOA) and direction of arrival (DOA), and line-of-sight (LOS) and non-line-of-sight (NLOS) localization.
