**Narrative**

RF scenario 12350 emulates a wireless environment where nodes 1 ~ 9 are in a fixed 3-by-3 grid mounted on the ceiling, while nodes 10 ~ 12 serve as flying UAVs moving in a circular trajectory repeatedly every 240 seconds.

- For scenarios 12351/12352/12353, the only difference to 12350 is the increased channel gain by 20/40/60 dB.
- For scenario 12353, the only difference to 12350 is the channel changed from single-tap channel to 3-tap fading channel.
- Scenario 12356 has 15 nodes where the first 12 nodes are the same as all other scenarios while the last 3 nodes serve as fixed UEs. The channel condition of 12356 is the same as 12352.

**Nodes Position and Trajectory**

The figure below shows the anechoic chamber environment together with the positions and labels of the 9 base stations and UAV-1. The trajectory of UAV-1 is also shown. UAV-1 performs an 8-shape around the two racks with goods, and it comes back to its original position.

The figure below shows the anechoic chamber environment together with the positions and labels of UAV-2 and UAV-3 for all scenarios, and of the three UEs of scenario 12356. The trajectories for the UAVs are also shown. UAV-2 performs a circle on the left rack, while UAV-3 makes the circle on the rack on the right. The speed of the three UAVs is the same, meaning that UAV-2 and UAV-3 perform twice their trajectories while UAV-1 makes it once.
