3. doc.: IEEE 802.15-15-0185-00-003e Submission Technical guidelines document (TGD) (IEEE 802.15 Doc. 15/0109r2) Sub-clause 4.3 Wireless data storage Wireless storage devices include wireless flash memory devices, wireless SSD (solid-state drive) devices, game cards and other electronic devices. -- Beginning of inserted text – The wireless storage devices may be used as a smart poster located in public spaces such as signage on a street or at a movie theater, wall boards at an airport or a railway station, guidance milepost including a map, shop information in a shopping mall. The devices can also be used as a portable device to store private information or large multimedia contents. In the use case of smart posters, a user can take any data file from the standalone storage device on a billboard to her/his mobile device by means of a touching action. In the use case of portable storage devices, the wireless connection is established as soon as a user places his/her storage device on the indicated area (or a reading pad) of a TV or a PC. The wireless storage device remains linked until the user takes the device away. In order to provide good user experience, the wireless storage devices should be capable of operating with limited power source. -- End of proposed change -- Mach 2015 Seok-jin Lee (ETRI) et al.Slide 3 Proposed change for SG3e TGD
