Outdoor-to-Indoor Channel Dispersion and Power-Delay Profile Models for the 700 MHz and 4.9 GHz Bands

Abstract

We present outdoor-to-indoor channel dispersion results based on measurements made in several representative urban environments. Root-mean-square delay spread values of less than 90 ns were extracted from measured power-delay profiles. We represent the power-delay profiles by exponential functions that can describe the multipath profiles for 700 MHz and 4.9 GHz frequency bands and extract a power delay profile model for the 700 MHz band that utilizes seven taps
