The term "omnidirectional" refers to the ability to receive or transmit signals equally well in all directions. This concept is commonly used in various fields, including telecommunications and audio technology. For example, an omnidirectional microphone captures sound from all angles, making it ideal for recording environments where sound sources are not fixed. In contrast to directional devices, which focus on a specific area, omnidirectional devices provide a broader coverage. This feature is beneficial in applications like wireless communication, where signals need to reach multiple receivers without being limited to a specific direction.
