A Giga-IR transceiver module embedded with a mobile phone communicating with a transceiver module on the PC side. Transmission and reception ports are separated. The hole on the left of the two holes on the right of the mobile phone is for transmission, whereas the one on the right one is for reception.Bluetooth has been at the top for quite sometime now, but I still can’t stop thinking about the new KDDI technology (GIGA-IR) that allows you to copy a full cd in a second. 1Gbps speed simply blows past anything we have right now in Bluetooth or any other mainstream technology. Now this is the technology for the speed demons!
