Common Mistakes to Avoid
Common failures come from choosing the wrong modeling depth, under-managing scenario inputs, or spending too long on setup for studies that require faster iteration.
Choosing full-wave EM for coverage-style iteration without accounting for compute cost
HFSS and CST Studio Suite can sharply increase compute time for large propagation scenes and fine meshes, so these tools should be reserved for high-fidelity scenario studies. SPLAT and Predict are better aligned when faster coverage-style iteration and side-by-side scenario comparisons are needed.
Treating propagation models as plug-and-play without validating inputs and boundaries
HFSS and CST Studio Suite both require careful EM setup with correct boundary and port definitions to avoid nonphysical results. SPLAT and SPEKTRA still require correct environmental assumptions and parameter setup because outputs depend directly on the chosen modeling inputs.
Running propagation analysis without a repeatability mechanism for scenario comparisons
Predict’s scenario management is built for automated propagation runs and side-by-side comparison, which prevents result drift across iterations. RFS Wireless Assessor solves a similar repeatability problem using assessment workflow templates that standardize propagation inputs for consistent coverage studies.
Separating circuit design from propagation and link analysis when the workflow needs to stay coupled
Keysight ADS avoids disconnects by integrating propagation modeling with RF circuit co-simulation in one environment. NI AWR Design Environment reduces workflow fragmentation by coupling schematic-driven RF design to EM characterization and system-level RF simulation.
