Fraunhofer tests an LED lamp that will light up your PC at 3 Gbps

This would be really great! it opens unlimited possibilities!

Gigaom

When you think about broadband connections, you usually picture radio airwaves or wires, not ambient light. But the emerging field of LED broadband (sometimes dubbed Li-Fi) aims to turn your light bulbs into data transmitters by subtly manipulating the rate they flicker. One of the organizations researching such optical communications technology, Germany’s Fraunhofer, has hit a new milestone: a lighting system that could deliver up to 3 Gbps.

Fraunhofer’s Heinrich Hertz (yes, that Hertz) Institute said it has developed components in the lab that will allow off-the-shelf LED lights to transmit data at a rate of 1 Gbps on a single frequency. Since most commercial LEDs support three frequencies (or colors) of visible light, that gives the system a total capacity of 3 Gbps.

The institute has achieved this, in part, by expanding the size of each frequency transmission band from 30 MHz to 180 MHz. Basically, Fraunhofer has developed…

Global Unionism: The Peer-to-Peer Model | New Unionism Network

Social Network Unionism

draft3The transnationalisation of production, along with the rise of global supply chains, informalisation, financialisation, and connecting of world markets through informationalisation have all hit hard on workers. It seems to have become impossible to overcome the resulting divisions among working classes, who have been so radically abused by capital. These new structural forces have created an immense need for connected self-organisations of workers, built from the bottom up, and operating simultaneously at local, national and international levels. This article argues for a new global unionism that goes beyond the IWW experience and allows workers to connect local, national, regional and international struggles by aligning with other struggles in life.

distributed_networkPeter Waterman calls this model “Social Movement Unionism”[1]. In order to develop enough strength to turn the tide globally, we need to redistribute power to the nodes involved in collective subjectivity and action. This cannot happen without dismantling the giant hierarchies…
