A convenient and economical optical channel for wireless control in the space for residents is carried out with the beam from light-emitting diodes (LEDs) while they are working for illumination. In theory, optical wireless technology can be implemented with lower cost and consumes lower power than those done by radio. However, optical communication is usually found applied in infrared. In the study, the white light of a LED lamp with the intensity for home illumination is considered to build an optical channel for wireless control of home devices. To be convenient and economical, the mature infrared technology is employed. Although data bits can only move within the channel in 2500 bps at most, the hardware to receive them is compact and cheap enough to be included in consumer electronics.
