Background: Accredited RF certification campaigns for millimeter-wave wireless systems incur substantial execution overhead that is not addressed by existing measurement uncertainty literature. Above 60 GHz, waveguide-based measurement chains introduce three principal sources of latency: measurement chain reconfiguration overhead between sub-bands, unstructured calibration practice leading to unnecessary recalibration events, and setup-induced rework from late detection of measurement errors. These factors extend campaign duration and constrain laboratory throughput in a market where certification schedule is a competitive variable. Methods: A systematic methodology comprising three procedural elements is proposed and implemented in an ISO/IEC 17025 accredited RF test laboratory. The first element treats sub-band measurement sequencing as a technical optimization problem over a hardware transition graph, minimizing total reconfiguration cost. The second element replaces conservative overcalibration with explicit trigger criteria derived from chain stability thresholds. The third element introduces a structured four-step pre-measurement verification procedure that detects setup errors before measurement begins rather than after results are obtained. The methodology was implemented across seven millimeter-wave fixed wireless access certification programs conducted at 60–80 GHz under FCC Parts 15 and 101. Results: Mean campaign execution time was reduced by approximately 29% relative to a matched baseline (mean reduction 6.4 working days per program; paired t-test: t(6) = 31.82, p ≪ 0.001; 95% CI 5.93, 6.92 days). All seven programs showed execution times below the baseline mean. No setup-induced rework cycle of the targeted type was recorded during the methodology period. Conclusion: The proposed methodology achieves a measurable and statistically significant reduction in certification campaign execution time without modification to measurement instrumentation or calibration infrastructure. Replication across additional laboratories and frequency ranges above 110 GHz is identified as the primary direction for future validation.
