An IR (infrared) remote control requires line of sight to control its equipment and typically has a range of about 30 feet. An RF (radio frequency) remote control signal may be sent through walls and floors and even reach inside cabinets. RF commands can usually travel at least 60 feet but some well-designed systems have been known to reach up to 200 feet in friendly environments. RF signals may also be easily repeated and/or amplified for even longer ranges if necessary. more
