  4.1 Video measurement

  At the topmost 17th floor, turn on one device (No. 7), place it stationary in the stairwell. Start the second device (No. 23), connect the camera (with a bitrate of 1024) and move it down the stairs. Stop when the signal-to-noise ratio of the two devices is around 20. As shown in the figure below:

At this point, start another device (52), place it at the current device's position, and proceed as the device connects to the network. Stop when the signal-to-noise ratio of the 23rd device and the 52nd device is around 20 dB, as shown in the following figure:

At this point, turn on another device (number 22), place it at the current device's position, and proceed as before after the device connects to the network. Stop when the signal-to-noise ratio of device 23 and device 22 is around 20 dB, as shown in the following figure:

At this point, turn on another device (number 24), place it at the current device's position, and proceed as before after the device connects to the network. Stop when the signal-to-noise ratio of the 23rd device and the 24th device is around 20 dB, as shown in the following figure:

At this point, turn on another device (number 21), place it at the current device's location, and proceed as before until the device disconnects. As shown in the following picture:
