Light bulb networks could be the next WiFi

A team at Boston University’s College of Engineering is working on low-power LEDs which could utilize an optical communication system to carry data wirelessly. Using a technique which rapidly switches the LEDs on and off data transmissions could be made via imperceptible flickering patterns, and each light would be its own network entry point at speeds of 1 to 10Mbps. The concept is more secure than current RF techniques because it requires linked devices be in line-of-sight, and the technology would draw far less energy than conventional radios. Says professor Thomas Little, “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.”

Google patent keeps airwaves competitive by selecting the cheapest

September 28, 2008

Rather than be tied down to any one carrier, why not keep changing carriers in real time based on whomever’s going to give you the best deal?

A new patent filed by Mountain View’s finest proposes exactly that, bringing together heterogeneous technologies — "community-wide" networks like WiFi and WiMAX along with GSM, CDMA, and so on — and an "auction system" that would let the user select (or allow the phone to automatically select) the best deal at the moment depending on their needs (available features or minimum speeds, time limits, and so on).

I doubt it will ever be released but the idea is brilliant.


Australian Photonic Chip to increase Internet speeds by100’s of times

July 9, 2008

Here’s a bit of perky news from down under, CUDOS (Centre for Ultra-high-bandwidth Devices for Optical Systems) have developed a new material ‘chalcogenide’ – a type of glass that allows data to  be transmitted at previously impossible speeds by converting light into electricity – essentially a ‘photonic switch’ that is capable (wait for it) …of being implemented into current fibre infrastructure!

Here’ the bit where I get ranty… and shout at the Powers that Be: Australia, Rudd, Telstra- here’s your chance to correct the slowness shown in bringing Australia up to the forefront of digital. Grab this one and move fast! It looks like a golden opportunity 🙂
