This slide summarizes the key findings regarding bandwidth configuration. The results show that increasing bandwidth consistently reduces latency and improves throughput across all tested distances. This means that allocating more spectrum resources can significantly enhance communication performance, especially in terms of transmission speed and responsiveness.
However, distance remains the dominant factor limiting communication performance, particularly at longer ranges. Even with increased bandwidth, the effects of path loss cannot be fully eliminated. Communication quality at long distances is still substantially worse than at short distances.
Overall, these findings indicate that bandwidth expansion is an effective but limited strategy. While it can alleviate performance degradation, it cannot fully overcome the fundamental constraints imposed by distance and path loss. Therefore, bandwidth allocation alone is insufficient and must be combined with distance-aware trajectory planning and energy-efficient communication strategies for practical UAV-ISAC deployment.
