Don't blame me for Ted Talks. Since they won't pay me a royalty for using my name, I've disassociated myself completely from them.
I'm also not responsible for Ted Airlines. https://en.wikipedia.org/wiki/Ted_(airline) I'm certainly not responsible for Ted the movie. http://www.imdb.com/title/tt1637725/ Ted Eckert Microsoft Corporation The opinions expressed are my own and do not necessarily reflect those of my employer, Ted Bundy, Ted Kacynski, Ted Cruz, Teddy Roosevelt, Ted Turner, Ted Danson or the anybody using the Ted word processor<https://en.wikipedia.org/wiki/Ted_(word_processor)>. -----Original Message----- From: Brian O'Connell [mailto:[email protected]] Sent: Monday, December 11, 2017 11:36 AM To: [email protected] Subject: Re: [PSES] Li-Fi Three observations. 1. would have side-effects somewhat analogous to BPL on EMC. And the up/down rate would probably have same problems and delay as satellite internet. 2. different modality of old tech - remember the science fair projects using laser com from bazillions years past? 3.

(IIRC, it was omni-directional infrared.) I think they were suggesting it for sharing of a printer within a multi-computer office, or for linking test equipment into a lab's mini-computer. While I can see some uses where a modulated light source, powerful yet inexpensive, would be a good data link, I can also see a few problems, the first of which is bi-directionality and the second is data capacity ahead of the optical links. As for his hints of vehicular applications, we still haven't eliminated rain, smoke and fog. Call me cynical, but whenever somebody puts a box on stage and does magic engineering, I become skeptical. Whaddya mean, you don't want to get into the details? Altogether, Li-Fi is yet another path. Ubiquitous LED's make it more attractive, but not quite a standing ovation quality concept.
