Heuristic modelling of path loss inside residences at 677MHz

Abstract

This study is based on the previous works conducted for the purpose of determining the Digital Terrestrial Television (DTT) coverage of National Broadcasting Network (NBN). It is also based on the results of indoor measurements conducted at 28 residential sites using live broadcast at 677 MHz. Penetration loss and path loss were investigated and a great contributor of indoor signal reduction in the four residential classifications considered, namely Class A, B, C and D. The focus of this study is to develop a statistical path loss model by measuring indoor losses caused by penetration and path loss inside residences using fixed and portable indoor antenna at 1.5m. The indoor path loss models developed for four residential classes were further calibrated for improved accuracy using heuristic approach.
