Abstract: This paper presents results from the measurement in indoor office scenario at 3.5 GHz. The measurement was performed using vertical-polarized dipole antennas (VDA) and omni-directional array (ODA). Three cases including corridor-to-corridor, corridor-to-room and room-to-room, have been measured and comprehensive propagation characteristics have been investigated. Based on the measurement, large-scale, delay and spatial models are built and compared with the standard models. Path loss turns out to be 3-5 dB smaller in indoor line-of-sight condition, while it is larger in non-line-of-sight condition because of the attenuation of concrete walls. Delay spread is the maximal in corridor-to-corridor case due to a strong reflection multipath component and angular spread in space domain is much larger than standard models in indoor scenario.
