Many infrared devices such as … The propagation of light waves in this band can be used for a communication system (for transmission and reception) of data. Line-of-sight and medium Laser Communications. IR communication has major limitations because it requires line-of-sight, has a short transmission range and is unable to penetrate walls. It is the use of infrared transmission technology in devices and equipments for sending data to other devices and/or controlling them wirelessly by human operators. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons It is the use of infrared transmission technology in devices and equipments for sending data to other devices and/or controlling them wirelessly by human operators. The main reason for using the IrDA protocols had been wireless data transfer over the "last one meter" using point-and-shoot principles. J    Many limitations exist, like the need to have line of sight, transmitter to receiver, however even with these limitations there are many applications for this type of wireless system. Infrared Wireless Communication The term “infrared” refers to electromagnetic waves whose wavelength is shorter than that of visible light.
