Infrared Based Wireless Optical Audio Transmission

In the modern world, a huge amount of information is exchanged and the confidentiality of information must be emphasized when communication takes place. Infrared communication has high directionality and can identify the person with whom you are communicating, which is different from wireless communication in which information diffuses, allowing for high confidentiality to be maintained. Hence, we attempt to build an Audio/Voice Transmitter that is receiver-selective due to high directionality. Infrared communication has no harmful effect on the human body. It is therefore not necessary to worry about using IR in crowded places. Compared with the wireless communication with a maximum speed of about 100 Mbps, the infrared communication has a potential of 1 Gbps. It also has a much shorter wavelength than wireless communication, which is easily enough for broadband communication. It is optimal for when large-volume data such as video must be sent at a high speed.
