Selection and adjustment of propagation models to compute the electric field strength for exposure assessment purposes in urban environment

This work deals with the selection of the best suited propagation models for computing electric field strength for exposure level assessment in urban environments in Colombia. The selection is based on the comparison of numerical results obtained using a well known commercial tool and measurements performed in the bands assigned in Colombia to the Digital Television Broadcasting (470 MHz-698 MHz) and Digital Radio Trunking (806 MHz-898 MHz).
