Abstract:
This paper presents channel measurements and modeling at 28 and 160 GHz in an industrial-style open office
environment with angular information at the receiver. Channel impulse response snapshots are captured at 135
measurement positions for both frequencies and are evaluated in terms of power metrics, delay, and angular
characteristics. Frequency-dependent models for path loss, delay, and angular spread of arrival and K-factor
are estimated, and large-scale parameter cross-correlations are evaluated. The measurements are compared to
the 3GPP TR 38.901 channel model in the Indoor-Office and Indoor-Factory scenario. Results show that delay and
angle spread are not frequency dependent in this environment although twice as many multi-path components were
identified at 28 GHz compared to 160 GHz.
