Wireless Communication Systems

 Wireless Communication Systems:

Wireless communication systems based on light currents utilize light signals for data transmission. Infrared (IR) communication is commonly used in remote controls, while visible light communication (VLC) enables high-speed data transfer using LED lights. Topics in this area include the principles of IR and VLC, modulation schemes, line-of-sight requirements, channel capacity, and applications such as indoor positioning and data communication in environments where radio frequency (RF) signals are restricted.
