We first noted it back in 2008: the possibility of using LED light bulbs for secure and directional wireless internet access. Well, the Fraunhofer Heinrich Hertz Institute is claiming that speedy data rates of up 3Gbps have proven feasible in its labs. The boost comes from its latest enhancements, allowing the 180Mhz frequency to be used over the usual 30Mhz, which apparently leaves extra room for moving data. If you'll recall, that's a significant leap over the 800Mbps top speed
