Scenarios 16 is designed to study indoor blockages. It has two stationary units, namely Unit 1 and Unit 2, as shown in Fig. 5. Unit 1 hosts a 60 GHz mmWave receiver equipped with a 10-degree beamwidth (20 dBi) horn antenna and an RGB camera, while Unit 2 hosts a 60 GHz mmWave transmitter with an omni-directional antenna. The 60 GHz transmitter and receiver are controlled by two laptops and the transmit/receive signals from the laptops and the transmitter/receiver pass through two 2901 NI USRPs. The two units coordinate the data collection using an IEEE 802.11-based control/communication channel. The transmit/receive waveform adopts an OFDM structure with 20MHz bandwidth and 64 subcarriers. The total transmit power from Unit 2 is limited to 30 dBm. Please refer to the detailed description of the testbed presented here. 

Conference Room Moving Blockage: This is an indoor scenario where the DeepSense Testbed 2 and a moving metal blockage in the shape of a cylinder are deployed in a large conference room, as depicted in Fig. 5. The transmitter and receiver are placed facing each other (have LOS connection) with a separating distance of ≈ 8 m between them. The blockage moves back and forth between the transmitter and receiver in two straight trajectories spaced 1 m apart and at a speed of 0.0625 m/s. In order to get different signal propagation conditions and increase the variance in the collected measurements, the testbed is rotated around the center of the blockage path on the x-y plane as shown in Fig. 6, and the blockage is set to move again between the TX and RX in two trajectories with the same 1 m spacing. The testbed collects data samples at a rate of 1.13 samples/s. Each data sample contains (i) an RGB image and (ii) the receive power value, both collected from Unit 1.
