Wideband Propagation Channel Measurements in an Indoor Office Environment at 26 GHz

In this work, useful measurement results of the propagation channel characteristics in an indoor office environment at 26 GHz are presented. The parameters of both the floating-intercept (FI) and close-in (CI) free space reference distance path loss models have been derived from channel measurements. The time dispersion characteristics have been analyzed in terms of both the root-mean-square (rms) delay spread and the coherence bandwidth. These results allow us to have a better knowledge of the propagation channel characteristics and can be also used to evaluate the performance of fifth generation (5G) networks in indoor office scenarios.
