Soundgraph was established in 2000 as a spinoff from Samsung. Their latest product is the SoundGraph iMON 2.4G series of remote controls. Unlike traditional infrared remotes they use 2.4 GHz wireless. The advantage of this is that it will work through walls and you don't have to point the remote at the receiver. Even though the 2.4 GHz band is used there were no problems running with an active wireless LAN nearby.
