  • channel modeling;
  • electromagnetic (EM) computational techniques;
  • finite difference time domain (FDTD);
  • indoor localization;
  • ray tracing (RT);
  • time of arrival (TOA)


This chapter introduces important parameters used in modelling a wireless channel. It provides a brief tutorial on the time of arrival (TOA)-based localization technique and discusses challenges presented by that technique. The chapter also focuses on measurement and simulation techniques related to the TOA-based technique. It then discusses the application of electromagnetic (EM) computational techniques in analyzing the effects of micrometallic objects and the human body on the accuracy of range estimates. The chapter uses finite difference time domain (FDTD) direct solution to Maxwell's equations as well as ray tracing (RT) using the geometric and uniform theory of diffraction. The results of computational methods are compared to the channel profiles obtained from a real-time frequency domain measurement to analyze the accuracy of the simulation methods.
