[CEATEC 2009] Sharing data among gadgets has been on KDDI’s plate for a while. While last year’s demo comprised of a prototype handset, this time around KDDI is using real handsets, even if that one is still a little thick (most cellphones are around here). At 1Gbps, the data connection should be fast enough to allow quick data transfers to and from the phone. Note that this is a theoretical speed and that measured data transfer should be much lower. IR has really gone a long way with KDDI. If you are interested in short-range communications, you might want to check our Transfer Jet post as well.
