ABSTRACT
Indoor wireless communications transport the vast information capacity using millimetre wave frequency band. Accurate characterization of the propagation channel is an important requirement for design and implementation of a local area network inside buildings. A tool for prediction of electromagnetic filed strength in indoor communications has been presented. A 3D ray tracing model is developed based on accurate electromagnetic theories that incorporate polarization characteristics. Propagation mechanisms for reflection and transmission are included in the model. The developed software enables prediction of the signal strength at any receiving point of the specific indoor environment. This deterministic model is compared with Motley-Keenan model. The obtained results from both models are compared with measured data. The ray tracing model is used with measured electromagnetic parameters. Non-destructive free space measurement method for the measurement of complex dielectric constant of the walls and other obstacles is used. The accuracy of the model enables the usage of it for characterization of a typical indoor environment for the performance evaluation of wireless local area network.
