RF at 300 Km/h, Part 2: When the Heatmap Looks Fine but Train Connectivity Still Fails - RF Isn't Everything | PRG 26

Following up on last year's intro to wireless onboard high-speed trains, this talk moves from design assumptions to field reality. Drawing on survey data, Wireshark traces, and Wi-Fi Explorer Pro captures, it digs into roaming behavior, airtime efficiency, spectrum reuse, interference, and failure modes invisible in design docs.

The focus: how RF analysis, packet capture, and live validation expose the gap between a network that looks correct on paper and one that performs at full train capacity. A deep dive for wireless engineers who need to design, verify, debug, and tune larger scale public Wi-Fi in production.
