Li-Fi in the ER

Imagine if you could eliminate the tangle of wires that snake across a hospital patient's body so machines can monitor his or her vital signs. Sounds like a great idea. But wirelessly transmitting data from the patient to the machines cluttering hospital rooms creates the risk of electromagnetic interference. So one group of researchers in South Korea is proposing that some machines use Li-Fi instead.

The team used visible light communications, also known as Li-Fi, to transmit readings from an electroencephalograph (EEG) over a distance of about 50 centimeters. "It's a very much friendlier means of transmitting biomedical signals in a hospital," says Yeon Ho Chung, an engineer at Pukyong National University in Busan. The group described their work in the IEEE Sensors Journal.

Li-Fi would benefit places that experience a lot of interference from crowded wifi nodes as well, as long as there are no side effects.

    And for that matter, why do we have "wireless fidelity" for wireless?

    Huh. I.. I never thought of it before. Why the hell do we use that term??

    Wikipedia [wikipedia.org] to the rescue:

    The Wi-Fi Alliance had hired Interbrand to determine a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'". Phil Belanger, a founding member of the Wi-Fi Alliance who presided over the selection of the name "Wi-Fi", also stated that Interbrand invented Wi-Fi as a play on words with Hi-Fi, and also created the Wi-Fi logo.
