Why bother with it? CAT 5e or CAT6 can hit 1 to 10 Gigabits (Gb/s), waay faster this tech. Heck, 500Mb/s is slower than 1394b which by the way can be used to make home networks.]]>Jan 23rd 2010 12:25AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/

this is true, line of sight is to be assumed, but try to think of some positives, say you have a bunch of metal warehouses that all have some PCs inside that all need to stay in sync, running cable in this scenario isn't feasible because there is probably going to be mostly concrete around them and if you ran the cables in the air from roof to roof, that probably wouldn't look good either. take some of these babies and pop them on top of each warehouse with some type of weatherproofing and bam...there you go.]]>Jan 21st 2010 6:24AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/these are nieche applications.

I do not want flame but a white LED with decent output power is as dangerous as a sub 1mW IR laser.
Also remember that LEDs would need to be specially designed to support such modulation speeds, while it is much less of a problem in case of DFBs]]>Jan 21st 2010 8:11AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/
Does the available bandwidth depend on the light's wavelength? Or do they just want it to look cool (but annoying after a minute of use)?]]>Jan 21st 2010 6:45AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/the higher the frequency of the modulating wave, the higher the data capacity of the channel - telecommunication 1:1. IR has longer wavelength than visible light (see http://en.wikipedia.org/wiki/Electromagnetic_radiation) so data carrying capacity of visible light should be higher. The problem is the power level, intensity as well as the fact that human eyes happen to be sensitive to this light.
Looking cool does not have anything to do with it. I guess they are just looking for low cost transmission sources for home use. I'd still think that there are better solutions with longer reach and similar bandwidth

thanks for that info :)

Anyway i think radio waves such as in wifi are still the way to go, the bandwidth is ok, they go through walls and they do not disturb people.]]>Jan 21st 2010 8:22AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/Jan 21st 2010 8:11AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/
A fire has broken out in an office building. Sirens blare and warning lights flash. But now because of work by the people of Siemens, those flashing lights are encoded with vital information about where the fire is and what the closest exit is. Want to know where the hot spot is? It's the giant blinking light.

Not every technology exists for you to sit on your ass and access the Internet faster.

If such requirements existed for your example about the fire then it would already be in place. The technology for this (morse code) has been around for a fair time.]]>Jan 21st 2010 9:08AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/
Wrong.

1- Morse code (even sped up) is amazingly slow (It's called binary).
2- Wheres the hot spot? Wifi can accomplish what I envision accept in my version the fire men aren't wasting precious seconds look for the hotspot. They find it intuitively.
3- To say that because this system I envisioned hasn't been instituted, therefore it can't be instituted is illogical.

Hand held devices have only been around a few years. Give it time. We'll eventually figure out how to properly employ them.

It doesn't therefore there is no need for this technology to be applied in this way.

Regarding all of you points there - why couldn't they do it over WiFi?

Last point because I'm bored at work - wouldn't a fire (heat and light) completely disrupt this technology? Communication by pulsing light would be useless in a fire-rescue scenario.]]>Jan 21st 2010 9:33AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/
Ok. You got me. Environmental conditions would disrupt this technology. You mentioned fire/light, but smoke would be far more crippling (so you get half credit).

In response to you inability to understand: a wifi signal is not a visible signal, so harder to locate than a visible light (b/c you can see light) Do you really want a bunch of people running around during an emergency w/their eyes glued to their handheld's as they frantically search for a hot-spot?

My point is this: We already use lights to convey information, to add another level of information to what already exists is not revolutionary, just logical.

Our needs don't dictate adoption of new technology. Capital does (It's called capitalism).]]>Jan 21st 2010 10:03AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/You don't need to physically locate a WiFi signal to use it so I don't understand how this is advantageous. If you did for whatever reason then some kind of light bulb (or laser?) attached to the router/access point would do the trick.

Human's don't really use lights to convey information. It is possible (morse code on Navy ships circa WWI) but not really common in today's age.]]>Jan 21st 2010 11:30AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/You're right. I totally forgot about:

Stoplights, taillights, warning lights, power indicator lights, Etc.

Just b/c the messages are simple- "Stop", "Power is off", "I am braking"- doesn't mean that they aren't being used to communicate. ]]>Jan 21st 2010 12:22PMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/ Wireless power]]>Jan 21st 2010 9:26AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/Jan 21st 2010 11:40AMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.youtube.com/watch?v=sH0R01gP3m0#t=1m41s]]>Jan 21st 2010 1:45PMhttp://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/http://www.engadget.com/2010/01/21/siemens-gurus-hit-500mbps-with-white-led-lights-dare-you-to-bli/Jan 21st 2010 1:54PM
