What is the distance range of wireless microphones?
Rather than quote a specific maximum operating distance, most manufacturers of wireless microphone systems give a “typical” range. For most systems with a transmitter output power between 10-50mW, the typical range may vary from 100 ft to 300 ft. The lower number represents a moderately severe environment (lots of RF in the area) while the upper figure might be achieved in absolute ideal conditions. (very little RF in the area) Extremely poor conditions could result in a range of only 50 feet or less. It is impossible to accurately predict the range of an arbitrary wireless microphone system in an arbitrary application.
