Development of a Path Loss Model for Wave Propagation Into Selected Buildings at Universiti Putra Malaysia

In this thesis, the development of path loss prediction model for wave propagation into buildings at Universiti Putra Malaysia is described. Field strength measurements due to three base stations were carried out in three different buildings in the Universiti Putra Malaysia campus. The measuremen...
