Thus, even if the speakers need to be wired, the control system doesnt have to be. The iRemotes take advantage of mesh networking, so that even if one of them is out of range of the receiver, another iRemote will forward the message traffic. Niles wireless handheld remotes, known as iRemotes, use 802.15.4 wireless links to talk to each other, and to the central receiver, the GXR2. Control of the system, however, is wireless, using 802.15.4/ZigBee technology, which operates in the 2.4 Ghz radio frequency (RF) band. In some respects, the ICS system is conventional in that it uses a central receiver head end containing the power amplifiers and speaker wire fanning out to the various rooms to be served. Niles Audios IntelliControl ICS system is a good example of this retrofit technique in action. Without the need to wire, dealers can do substantial (six- or eight-room) installations in a day or less, depending on how elaborate an install the customer is looking for. and Canadian custom installers, who highlights speedy installation as one big benefit to wireless.
