Lightbulbs next wifi hotspots?

According to Cellular-News, the College of Engineering at Boston University is launching a program aimed at developing the next generation of wireless communications based on visible light rather than radio waves. From the article:

“Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires,” said BU Engineering Professor Thomas Little. “This could be done with an LED-based communications network that also provides light – all over existing power lines with low power consumption, high reliability and no electromagnetic interference. Ultimately, the system is expected to be applicable from existing illumination devices, like swapping light bulbs for LEDs.”

Fewer wires and increased communication with all of your devices sounds like a winning advancement to me. The technology for LED-based wifi has just begun, so I’m cheering for the labs at BU to work diligently to get this to market.

Eye-Fi eliminates the need for USB wires

Eye-FiEye-Fi is an SD memory card that wirelessly uploads your photos to your computer without the need for an extra wire or stand alone card reader. This little 2 GB card will make those wires and cables obsolete. Here at Unclutterer, we are always on the lookout for products that conquer the wire beast that lurks around your desk or entertainment center.

Unfortunately, the folks over at Engadget have thrown cold water on the Eye-Fi by giving it a marginally poor review. It’s at least a step in the right direction, and we look forward to future generations of this wireless SD card.
