Compare 433 MHz and 915 MHz for range, antenna size, regulations and IoT links.
RF design depends on wavelength, antenna geometry, ground plane, cable loss, enclosure material, matching network and installation height.
Use calculators for first estimates, then validate with measurement, datasheets, VNA or field testing.

The result is based on the displayed formula and input values. Real hardware can be affected by tolerances, temperature, layout and component limitations.
Use it as an engineering estimate. Always verify final production designs with datasheets, simulations, manufacturer recommendations and measurements.
Start with electrical requirements, then check datasheet limits, thermal behavior, availability, safety margin and compatibility with your project.
Cheap modules can work for prototypes, but you should verify real current rating, heat, protection features, documentation and long-term reliability.
Yes. Use related calculators to estimate current, voltage drop, power loss, heat, range or runtime before selecting parts.
Range depends on antenna design, frequency, link budget, path loss, cable loss, installation height, interference and receiver sensitivity.
Yes. RF performance changes with enclosure material, ground plane, placement, nearby objects and installation height.
