TopoWave: RF Link Planner

Plan radio links with terrain, not guesswork. TopoWave helps amateur-radio operators, mesh-network builders, wireless installers, and field teams evaluate terrain between sites before heading out. Place two points on the map, enter antenna and radio details, and run a terrain profile to inspect line of sight, 60% first-Fresnel-zone clearance, obstructions, free-space path loss, and an estimated link budget. EXPLORE TERRAIN VISIBILITY Place a transmitter, choose range, direction, frequency, antenna height, and receiver height, then generate a color-coded terrain-visibility map. Choose overview, standard, or detailed sampling for studies from 1 km to 100 km. KEEP A PLANNING LIBRARY Save sites, targets, equipment profiles, link setups, coverage setups, and frozen analysis results on your device. Compare saved links or terrain-visibility studies without rerunning the calculation. EXPORT USEFUL RESULTS Create PDF reports and share data as CSV, GeoJSON, KML, PNG, or a concise text report for documentation and field work. DESIGNED FOR PRACTICAL RADIO PLANNING - Presets for common amateur-radio, LoRa, mesh, Wi-Fi, and ISM bands - Custom frequencies from 0.1 MHz to 100 GHz - Adjustable transmit power, antenna gains, cable and connector losses, polarization mismatch, clutter allowance, receiver sensitivity, and planning reserve - Height recommendations for difficult paths - Apple Maps with manual coordinates or optional current location - Terrain-source details and attribution in every completed result - No advertising or cross-app tracking TopoWave is a planning aid. It does not model every building, tree, weather condition, interference source, diffraction effect, antenna characteristic, or local rule. Terrain and elevation resolution vary by location. Confirm regulations, equipment specifications, and critical links in the field. Guest access includes a limited number of terrain analyses. Optional Sign in with Apple provides 10 terrain analyses per day. Saved planning data stays on your device.
