RF remote control - Computer Definition
(Radio Frequency remote control) A handheld, wireless device used to operate audio, video and other electronic equipment using radio frequency (RF) transmission. Unlike the more common infrared (IR) remotes, RF remotes do not require line of sight and do not have to be aimed at the equipment. In fact, RF remotes can be operated from another room. RF Receivers (Base Stations) Are Required Since most equipment is IR based and comes with an IR sensor located on the front panel, the RF must wind up as IR. This is accomplished with an RF receiver, which is a base station and antenna, that accepts RF signals and converts them to IR. For use inside equipment cabinets, the receiver typically has an "IR blaster" that showers IR signals to all components by reflecting off the closed cabinet door. The RF receiver also has sockets for several IR emitters (IR flashers) that are wired to, and pasted directly over, the IR sensors in the equipment for precise aiming. See IR remote control and RF.
