Frequency Modulation (FM) Technology Overview
Frequency modulation or (FM) is a means of transmitting audio using electromagnetic waves. This same technology is used by local FM radio stations to broadcast music. FM signals can travel through most barriers
–walls, floors, and ceilings. The distance a signal travels has many different variables such as Radio Frequency (RF) output power, the type and placement of the antenna, and the broadcasted frequency. Unlike infrared, FM transmission are not secure. This enables a receiver to travel further distances from the source. This section of the manual will help you design a system that will get the best range and least amount of interference.
