How to Power Your Wi-Fi with LED
Everyone knows that your wifi laptops derive signal from multiple radio signals. Riding on the 2.4ghz band, these networks
make life a breeze as interconnectivity is maintained without cables. It’s a boon and has brought interconnectivity beyond the office network and straight into coffee shops and even airport lobbies. And now.. Boston University researchers have discovered a new way of shuffling data around and it takes the form of a standard LED light bulb.
The concept is nothing short of amazing. From what I read in a magazine, the technology uses low powered LED lights and then switch them on and off at a breakneck pace. The quick flashes remain visible to the user and keeps workspaces lit, but empowers gadgetry to communicate thru the flashing of shifting different patterns over time. The magazine boasts that speeds up to 10Mbps can be achieved through LED. Current draft-N technology doesn’t even reach this yet.
The researchers suggest mounting system on ceilings. With the array of lights aimed downwards you also maintain a secure network since it requires line of sight to function. Contrast this with wi-fi which leaks beyond buildings and leaves the network vulnerable to outsiders.
One thing nice about the system is that you have full control over the network. Want connectivity? Simply stride into a room lit with the wi-fi LEDS. Then to shut down the system, simply pop the switch on the wall. As the room goes dark, your network expires.
I do wonder… maybe it won’t take long for this to replace wi-fi. Many of us have fears of the detrimental effects wireless radio signals may have on our brains. Light strobes don’t carry the same risks.

I think that Draft N is considerably faster than 10Mbps

Wifi will allways be an option as long as people still pay for it
