Scenario-9: Multiple Fixed Single Mobile (MFSM)

This experimental setup will be an extension of the previous two scenarios, i.e., a drone moves through the coverage area of several fixed nodes, either through pre-defined waypoints or through autonomous navigation, as shown in the adjacent figure. The towers may be within the same site or different AERPAW sites, e.g., one fixed node each in LWL, Town of Cary, and Centennial Campus, which may have sufficient coverage for high drone altitudes for long-range IoT links.

In this experiment mode, the example experiments may include: 1) Handover optimization for drones by semi-statically or dynamically changing handover parameters; 2) Triangulation and tracking of the drone at the base stations; 3) LTE cell association based on RSRP/RSRQ; 4) Interference characterization to other terrestrial cells/users; 5) Evaluating different frequency reuse patterns; 6) Observe the behavior of the drone with fake BS(s). Experimental insights from Scenario 3 and Scenario 6 will play a critical role especially in characterizing the drone handover/mobility and cell association process. This experimental setup could be a forerunner of a fully operational autonomous drone setup, where a UAV can move autonomously while maintaining connectivity to a certain network service provider.
