Site-specific modelling of indoor radio wave propagation

Abstract

Design of wireless communication systems inside buildings requires accurate site-specific characterization of indoor radio channel. In the complicated indoor communication environment, transmitting and receiving antennas are often inevitably installed close to wall corners, edges and other complex lossy scatters, where exact solution to scattering field distribution is not available. Channel models based on simplified radio propagation theories make it impossible to study effects of these generic structural features. On the other hand, application of accurate numerical analysis method to the entire modelling area is neither practical because of the computation resource required, nor is it necessary for wide open area without many indoor objects.
