Clear explanations of RF frequencies, modulation, coding and wireless range.
ASK and FSK can operate on the same nominal frequency yet behave very differently around electrical noise. The modulation, receiver bandwidth, data rate and packet design must be evaluated as one radio link.
A relay’s headline current rating is usually based on a resistive test load. Motors, solenoids, lamps, and other real-world loads can demand far more at startup and are harder on contacts when switched off. Here is a practical way to size and protect a wireless controller.
