Should I Use 72 MHz or 216 MHz?
Frequency modulation (FM) is a means of transmitting audio using electromagnetic waves. This same technology is used by local FM radio stations to broadcast music. Listen Technologies’ Stationary FM products wirelessly transmit audio from a sound source to portable receivers with headphones; primarily for assistive listening and language interpretation applications. FM signals can travel through most barriers – walls, ceilings, and floors. 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 frequency band.
