Our 1997-era selves would die with envy right about now. Fraunhofer has developed a new generation of infrared transceiver that can transfer data at 1Gbps, or well above anything that our vintage PDAs could manage. While the speed is nothing new by itself -- we saw such rates in 2010 Penn State experiments -- it's the size that makes the difference. The laser diode and processing are efficient enough to fit into a small module whose transceiver is as large as a
