Replication data for the paper titled Evaluating 5G-connected IoT for Power Line Temperature Prediction: Real-World Latency and Cost Trade-offs Between MEC and Cloud presented at the 8th International Workshop on Recent Advances for Multi-Clouds and Mobile Edge Computing (M2EC 2026) held in conjunction with the 40th International Conference on Advanced Information Networking and Applications (AINA 2026). April 8-10, 2026 in Wellington, New Zealand. Table 2: P99 Tail Latency by Cloud Region and Client Location Note: The measurement at (9388, Fjordgård) was conducted over an optical fiber connection rather than 5G.
