Li-Fi technology: Transfer rate up to 224 Gbps!

What is Li-Fi?

Li-fi is a new way of communication between mobile devices. It is based on the fact that intensity of a light emitted through an LED can be modulated. It can be increased or decreased in such a way which can be used to transfer data. This modulation is performed in such a way that it can’t be seen with a human eye.
Li-Fi technology was introduced by Professor Harald Haas of the University of Edinburgh. He demonstrated this technology in his TED talk in 2011 which has attracted more than 1.7 million viewers.

How does Li-Fi work?

LED are small diodes which emit photons when current is applied. If current is varied, the intensity of LED also varies. Photons are emitted from LED which can be received by a receiver unit. If this beam of photon is modulated, it can be used to send information at the speed of light which can later be demodulated. Because LED are semiconductor devices, this modulation can take place at much higher speed than what a human eye can perceive.
Such LED devices can be fixed in ceiling which will provide us light for daily use and a light fast internet connection as well.

Li-Fi


Features:

Li-Fi provides much better features than Wi-Fi technology.
High speed data transfer
Since light is the medium through which data is being sent, it is the fastest way of data transfer . It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second. Parallel data transfer is also possible which makes it even more efficient and faster.
Low cost implementations
If costs lower than Wi-Fi and other radio devices. It uses fewer component to transfer data.
Efficiency and safety
LED are already efficient semiconductor devices and requires very low voltages to operate. Like Wi-Fi it doesn’t spread waves with signals and data everywhere in the environment which can be picked up by other devices and that makes it much more safer.

Conclusion:

Li-Fi will revolutionize the world by providing lightning fast data transfer speeds to a normal users. With this technology it is estimated that you will be able to download more than 20 movies of 1Gb size each in just 1 second. Wow!

Why am I getting I/O Error #2038 in dailymotin when uploading to My Files?

 
 
 
This error has to do with the way security is handled inside of the Adobe Flash Player browser plugin.  There are multiple versions of the plug-in that behave differently depending on which browser you use (Internet Explorer, Firefox, Chrome, etc.).  Our uploader uses the Flash plugin to make uploading multiple files at once possible.  If the Flash Player is not installed on your computer, or your Flash browser plugin is disabled, you will only be able to upload one file at a time.
 
Our uploader is configured to bypass Adobe's internal security handling procedures (which is part of the reason this error occurs), however, from time to time updates to the Flash Player can apparently interfere with this.  The fun part is that it doesn't affect everyone or every browser the same way, or even at all and unfortunately there is nothing we can do from our end when this occurs.
 
Here are some possible solutions:
  1. Make sure your internet browser is up to date by checking its About page (usually found under the "Help" option on the main menu).
  2. Try using another internet browser that is already installed on your computer (or get Firefox, Chrome, or Safari).
  3. Close any open internet browser windows.  Go into your computer's programs area where you can see what all is installed and uninstall Adobe Flash Player and any references to Flash Plugin (may have the name Shockwave or Macromedia), then go to http://get.adobe.com/flashplayer/ to download and install the latest version of it.
  4. If all else fails, go into the settings, extensions, or plugins area of your internet browser(s) and disable the Flash Player plugin so you can at least do single file uploads until a patch or update to the Flash Player is released (you'll usually know because your computer will visibly remind you about the update).
