While IR is still quite useful for certain things, transferring data between devices is something very few people still use it for. Japan's KDDI R&D labs, however, have managed to increase the transfer rate 250 times to 1Gbps with a semiconductor laser that blinks incredibly fast. Although 1Gbps is fast, it doesn't quite transfer a full CD of music in less than a second (which is 650MB). Point is, if they can manage to put this into cellphones, we'll finally be able to get our contacts over really really fast. [Digital World Tokyo]
