Abstract: Industrial automation has created a high demand for private 5G networks, thedeployment of which calls for an efficient and reliable solution to ensurestrict compliance with the regulatory emission limits. While traditionalmethods for measuring outdoor interference include collecting real-world databy walking or driving, the use of unmanned aerial vehicles (UAVs) offers anattractive alternative due to their flexible mobility and adaptive altitude. AsUAVs perform measurements quickly and semiautomatically, they can potentiallyassist in near realtime adjustments of the network configuration andfine-tuning its parameters, such as antenna settings and transmit power, aswell as help improve indoor connectivity while respecting outdoor emissionconstraints. This article offers a firsthand tutorial on using aerial 5Gemission assessment for interference management in nonpublic networks (NPNs) byreviewing the key challenges of UAV-mounted radio-scanner measurements.Particularly, we (i) outline the challenges of practical assessment of theoutdoor interference originating from a local indoor 5G network whilediscussing regulatory and other related constraints and (ii) address practicalmethods and tools while summarizing the recent results of our measurementcampaign. The reported proof of concept confirms that UAV-based systemsrepresent a promising tool for capturing outdoor interference from private 5Gsystems.
