RPB868s are used in pairs, with each unit having 4 inputs and 4 outputs: the inputs from one unit are wirelessly copied to the outputs of the other unit, and vice versa. The units are used to replace simple on/off cables where it is either impossible, inconvenient or impractical to lay them. For example, an on/off switch in one location could be used to control power to a device in another location, without the need to run physical wires between the two locations. The units have a range of 2-16km (depending on the type of antenna used). |
