The operating demo SD card is installed to a handset via SD card adapter. For now, you can't store datas in the card because it's full with radio chips and no spaces for memory chips.


The usage varies. You may connect your handset and your pc without any wires and cradles, or connect to HDD recorder to download huge video data. Currently there's no ad-hoc mode but it's soluble in principle.


There's no concrete schedule for commercialization yet. They say that technically it's practicable enough but market is not ready to accept and apply it.
