Submission Slide 4 Guixia Kang, BUPT July 2011 doc.: IEEE 802.11-11/0970r1 Use case 1i : Outdoor Healthcare System (Proposed) • In disaster region, a temporary first aid station will be built soon, and most victims will be collected in the station, and receive medical treatment. • When disaster happens, the communication network and internet infrastructure might have been destroyed, an IEEE 802.11 based wireless network should be built immediately, to support the transmitting of the medical data in the temporary first aid station . • Transmission of large amount of data should be supported, because there might be a lot of victims. • Open air environment (probably with rubble). Submission Slide 5 Guixia Kang, BUPT July 2011 doc.: IEEE 802.11-11/0970r1 Use case 1i : Outdoor Healthcare System (Proposed) • Scenario in this use case is kind of like the pipeline monitoring scenario in Use case 1d: Sensors for industrial process automation. • AP/STA will be deployed as followings: – Place at LOS position with each other – If necessary, AP uses high gain antenna • STA should support a variety of devices in the terminal network • Submission – Medical terminal devices\Environment monitoring devices\Other devices Differs from 802.11s on: – distance between AP/STA will be large (~2km) – Rural (open air) or rubble environment – STAs with low mobility. – STA/AP’s have data handling ability (handled on the spot). Slide 6 Guixia Kang, BUPT July 2011 doc.: IEEE 802.11-11/0970r1 Use case 1i : Outdoor Healthcare System (Proposed) Disaster rescue medical service Location Outdoor Environment type rural\urban area (probably with rubble) STA/AP communication 2-way (healthcare data & control) Mobility Stationary ~ low (walking ) Traffic type • Periodic: several KBytes every sub-seconds (e.g. series of blood pressure, ECG, …) • Event-based: few 100 bytes per event Security requirement Commercial-grade STA/AP capacity STA:<100, AP<10 STA/AP category STA: Stationary, walking AP: Stationary Data handling AP supports data handling/aggregation Submission Slide 7 Guixia Kang, BUPT July 2011 doc.: IEEE 802.11-11/0970r1 Straw Poll 1 • TGah shall adopt the proposed use case 1i. Comment on the two basic application scenarios of use case 1i: 1)When disaster happens, for example earthquake, where most of the network infrastructures (except satellite) are destroyed; 2)In the wide rural area of China, where there are little rural families which have the nearby internet access through one 11ah AP.
