3. Submission doc.: IEEE 11-11/0333r1 Internet Access from Train at Station Actor(s): - Handset users Device sets: - Handset  Access Point  Internet Goal: - Let large # of STAs access to the Internet within a limited time Scenarios: - A crowded train stops at a station - A large # of STAs access to the Internet to download contents (e.g. Podcast, Tickets, etc…) during train staying at the station - STAs complete contents downloading. Users enjoy the downloaded contents inside the train Slide 3Akira Yamada, NTT DOCOMO, Inc. March 2011

4. Submission doc.: IEEE 11-11/0333r1 Information / Ads. Distribution Actor(s): - Handset users Device sets: - Handset  Access Point  Internet or specific server Goal: - Let large # of STAs access to the Internet within a limited time - Ability to update contents unknowingly Scenarios: - Distribute floor maps/ parking information / advertisement to handset users walking or driving by shops/digital signages/parking. - Owners of shops/digital signages distribute cooking recipe at supermarkets. - Users get advertisement or train timetable around LCD displays in train Slide 4Akira Yamada, NTTDOCOMO, Inc.
