Most of us techies use Bluetooth and WiFi because it is much faster and more efficient when used to transfer data between devices, compared to IR (infrared). KDDI R&D Laboratories have found a way to make IR reach speeds of 1Gbps. In fact that is 250 times faster than the previous limit of 4Mbps. They claim that they can transfer a full music CD in under a second. We hope that there are devices in the future that offer this new IR technology. But most likely manufacturers will stick with Bluetooth and WiFi.
