Use case 1e: Indoor Healthcare System (Comment)
In indoor healthcare system, the terminal device should be more flexible, low mobility should be supported.
AP/STA’s will be deployed at home.
Several users can share one AP/STA if possible.

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 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).

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
Medical terminal devices\Environment monitoring devices\Other devices
Differs from s 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).

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
