Li-Fi Scrubs Into the Operating Room

IEEE Spectrum  March 13, 2020
An international team of researchers (Germany, Czech Republic) set up multiple Li-Fi transmitters and receivers in a neurosurgery operating room in Prague. In a series of tests, the Li-Fi system managed to transfer data quickly and without complete signal loss. They achieved data rates of up to 600 megabits per second. Because Li-Fi uses higher-frequency light than Wi-Fi does, it could, in theory, have a higher bandwidth and therefore transmit data more quickly. Unlike Wi-Fi’s radio frequencies, which can pass through walls, optical light is easily blocked by humans or objects. To get around this issue, they used four transmitters and six receivers around the operating room, for a total of 24 channels between transmitters and receivers. Proponents claim that Li-Fi could deliver more reliable data transmission at faster rates than Wi-Fi….read more. TECHNICAL ARTICLE
