Z-Wave

A wireless network for controlling lights, heating and air conditioning, appliances, home security and home theaters from Zensys, Inc. (www.zen-sys.com). Z-Wave is designed for low-speed controls such as turning a device on and off or raising or lowering a function, and it operates in a mesh topology. Each Z-Wave device can relay signals from another device for better reception. Working in the unlicensed 902-928 MHz band, Z-Wave devices do not interfere with Wi-Fi and other products that use the 2.4 GHz band. See home control network.

A Z-Wave Remote

This high-end NevoS70 remote control from Universal Electronics sends Z-Wave signals to a base station that outputs infrared signals to various A/V components (see RF remote control). The S70 also includes Wi-Fi for viewing Web data, IP cameras and controlling one's own digital media. (Image courtesy of Universal Electronics Inc., www.mynevo.com)
