RF remote control
(Radio Frequency remote control) A handheld, wireless device used to operate audio, video and other electronic equipment using radio frequency (RF) transmission. Unlike the common infrared (IR) remotes, RF remotes do not have to be aimed at the equipment.
RF Receivers (Base Stations) Are Required
Most A/V equipment is IR based and has an IR sensor on the front panel. Because RF remote control signals must wind up as IR signals at the IR sensors, an RF receiver (base station and antenna) accepts RF and converts it to IR. Receivers are wired to an "IR emitter" (flasher) pasted onto the sensor of each device or to an "IR blaster" located inside the home theater cabinet. The blaster reflects off the closed cabinet door, showering IR signals to all the devices at the same time. See IR remote control, Wi-Fi remote control and RF.
