摘要:
A wireless communication interface for a portable wireless terminal and a system for wirelessly communicating by a portable wireless terminal with another device via a free space. The interface facilitates aligning the portable wireless device with another devices for improved communication. The interface including: a light source for generating a data-modulated visible light signal and outputting the visible light signal to the free space; an optical detector for generating an electrical signal by photoelectrically converting the visible light signal input from the free space, and for outputting the electrical signal. A demodulation unit demodulates the electrical signal input from the optical detector, and outputs a data signal.
