This paper investigates the penetration loss of an office building in indoor-to-indoor and outdoor-to-indoor mobile scenarios. The measurements were collected using our 60-GHz double- directional switched-antenna channel sounder. During measurement, the transmitter, mounted on a tripod, was placed in an office and outside of the building, while the receiver, mounted on a mobile robot, moved along an interior hallway. The penetration loss for a variety of building materials was predicted versus incident angle by electromagnetic propagation theory using the ITU-R Recommendation P.2040 model parameters and compared with the measurement results. The wooden door, plasterboard wall, and interior glass were observed to have penetration losses ranging from 26 dB to 41 dB, 12 dB to 32 dB, and 8 dB to 18 dB, respectively, while the exterior building materials exhibited even larger penetration losses, ranging from 30 dB to 67 dB.
