November 2015 doc.: IEEE 802.11-15/1383r0 Use case for home theater (1) Home theater devices are associated with the LRLP AP Controller (indoor mobile device) LRLP AP Set top box Home theater Speakers LRLP for control data TV Submission Slide 4 Minseok OH, Kyonggi University
November 2015 doc.: IEEE 802.11-15/1383r0 Use case for home theater (2) The central controller is most likely a mobile device Pairing is performed through an LRLP AP by the central controller (mobile device) After connection setup, either Wi-Fi Direct or Bluetooth may be used for user data transfer between non-AP STAs Submission Slide 5 Minseok OH, Kyonggi University
November 2015 doc.: IEEE 802.11-15/1383r0 Use case for home security (1) Door/window sensor, Gas sensor, Smoke detector, home appliances Door LRLP AP Outdoor mobile device Window Smoke detector LRLP for control Home appliances Gas sensor mobile+cable modem/xDSL for control Submission Slide 6 Minseok OH, Kyonggi University
November 2015 doc.: IEEE 802.11-15/1383r0 Use case for home security (2) Any abnormal state sends an alarm to the mobile device Requirements Fast wakeup time: From a dormant state, the communication must be reestablished quickly through bypassing login procedure, pairing, DHCP, etc. Reconnection procedure must be secure as well Submission Slide 7 Minseok OH, Kyonggi University
November 2015 doc.: IEEE 802.11-15/1383r0 Use case for indoor device control Gas value controller, Heater/AC, Home appliances, Surveillance cameras Gas valve controller Controller (outdoor mobile device) LRLP AP Heater A/C control Washing machine LTE+cable modem/xDSL for control Submission Slide 8 Minseok OH, Kyonggi University
September 2015 doc.: IEEE 802.11-15/1383r0 Use case for manufacturing (1) Data collection from sensors in a manufacturing house A chip maker is an example LRLP AP Vibration sensor Data analysis server Vibration sensor LRLP data collection Wired/wireless connection Submission Slide 9 Minseok OH, Kyonggi University
September 2015 doc.: IEEE 802.11-15/1383r0 Use case for manufacturing (2) A chip maker monitors the vibration pattern from various facilities Use the collected data to predict possible failures of the facilities Reduces downtime of manufacturing process and improves the yield Submission Slide 10 Minseok OH, Kyonggi University
September 2015 doc.: IEEE 802.11-15/1383r0 Use case for manufacturing (3) Requirements The stable data rate must be maintained even in multipath environment due to the dense and interfering facilities The number of sensors connected to the LRLP AP at the same time must be large enough To extend the coverage, an LRLP AP may be connected to another LRLP AP (multihop) and adaptive route selection between a server and sensors for multihop environment A connection between sensors and an analysis server must be secure Fast wakeup time on sensor devices Lightweight and low-power authentication scheme for sensors Submission Slide 11 Minseok OH, Kyonggi University
November 2015 doc.: IEEE 802.11-15/1383r0 Summary For home theater use case, pairing between LRLP STAs is performed through LRLP AP by a mobile device (an LRLP STA in the same indoor) for direct connection between A/V devices For home security use case, fast wakeup and secure reconnection for LRLP STAs are required For indoor device control use case, a mobile device can control the indoor devices collocated with LRLP STAs For manufacturing house, the connection should not be interfered by the manufacturing facilities, multihop is supported, and authentication is light Submission Slide 12 Minseok OH, Kyonggi University
