Low-power apparatus (LPA): Examples of low-power apparatus (LPA) include wireless microphones and wireless cameras, systems for cue and control communications, as well as synchronization of video camera signals. Low-power FM transmitters may also be included in this category, but their use is restricted and is only authorized for operation under specific conditions. LPA may be limited to a particular location (fixed) or used on a Canada-wide or province-wide basis (Electronic News Gathering (ENG) type), depending on its licence.
