Free-space indoor optical communication deploying pencil beams can offer ultra-high wireless capacity individually per user device. By means of a pair of crossed grating 2D steering of multiple beams by just tuning the wavelength of each beam can be achieved by wavelength tuning from 1505 to 1630nm. With radio over fiber techniques and optical carrier from the downstream signal and upstream transmission of a 60GHz band radio signal has been shown using adaptive DMT modulation. Angular Magnification by lens system is used in future for increasing coverage area.
