Determine about the infrared spectrum
(1) The spectrum for infrared is virtually unlimited, which shows the possibility of achieving extremely high data rates.
(2) The infrared spectrum is unregulated worldwide, which is not true of some portions of the microwave spectrum.
(3)Infrared light is diffusely reflected by light-coloured objects; therefore it is possible to use ceiling reflection to achieve coverage of a whole room.
what are the main problems of signal propagation?why do radio waves not always follow a straight line?why is reflection both useful and harmful?
