Frequently Asked Questions What types of devices can be controlled by the Harmony 890 remote? The Harmony 890 remote can control most types of devices that come with an infrared (IR) remote control. It is also capable of extending the capabilities of conventional infrared control by being able to send IR codes via another wireless technology called RF. What's the difference between infrared and RF wireless technology? Infrared signals are actually light pulses that are too low in frequency for human eyes to see. Like any other beams of light, infrared signals are directional, and can be blocked by obstacles. RF wireless technology works on the principle of radio waves. They are not directional and not affected by obstacles, so people don't have to point RF remotes at the components they want to control, and the signals can travel through walls, floors and cabinets. Does the Harmony 890 send RF or IR signals to control my gear? It sends both. The infrared signals can control equipment in the same room, within the remote's line of sight, but the 890 can also send the IR codes via a wireless RF stream to components hidden behind closed doors or in other rooms in the house. An RF Wireless Extender receives the RF signals, and then translates them back into IR codes that the equipment can understand. The RF technology being used at this time is based on the Z-Wave standard. On which frequency does Z-Wave operate on? Z-Wave uses the 900 MHz frequency band. This band was chosen because it has a range that's approximately 2.5 times greater than the 2.4 GHz frequencies used by common household cordless phones. By working within the 900 MHz range, Z-Wave networks not only offer longer-range operation, but aren't subject to interference from cordless phones and Wi-Fi home networks. What is the Logitech RF Wireless Extender? The Logitech RF Wireless Extender is an example of what is sometimes referred to as a "bridge receiver" - it takes an RF signal and converts it to IR commands. On its own, each RF Wireless Extender will command up to eight devices through its own IR emitter
