# What solutions, if any, are there for visible light transmission (VLC)?

I want to know what ways are there to transmit data using LED's that are available to us today.

I currently can find only one reasonable resource for this topic, which is this: http://www.siemens.com/innovation/en/news_events/ct_pressreleases/e_research_news/2010/e_22_resnews_1002_1.htm

Is there any other information about this or resources I can use? What is the highest frequency can you blink a under $5 led at? What about a photo diode or photo transistor that can respond at such frequencies for under$5?
