Scope of MBAN Task Group
Draft an amendment of for MBAN
This amendment defines a physical layer for IEEE in the 2360 to 2400 MHz band which complies with Federal Communications Commission (FCC) MBAN rules. This amendment defines modifications to the MAC needed to support this new physical layer.

FCC MBAN Rules
Allow use of the MHz band, on a secondary basis, for monitoring, diagnosing or treating patients (no voice).
MHz MBANS operations limited to health care facilities (indoor use only), which are outside exclusion zones
Must yield use of the band for the primary user
In exclusion zones, usage of the band may be for a limited time, on a scheduled basis and allowing for use of only part of the band
Healthcare facilities must file a Transition Plan that manages re-channelization out of the spectrum, to accommodate the primary user

5. May 2012
FCC MBAN Rules (cont)
An entity, called a FCC Band Coordinator, manages use of the band for Healthcare applications
Manages relationship with primary user and hospitals to determine what spectrum is available and at what time
Keeps track of which hospitals are within exclusion zones

7. Channel Switch Notification
May 2012
Channel Switch Notification
Description
A method for switching channels at a scheduled time
Use Case
The primary band user is scheduled to use the part of the band a healthcare device is using at a specific time. Usage is normally scheduled by the primary user many days in advance. The device must vacate the portion of the band the primary user requires at the scheduled time.

8. Coordinator Switch Description
May 2012
Coordinator Switch
Description
A method for switching a set of devices from one coordinator to another in a controlled manner.
Use Case
A patient with an array of sensors is located in a ward with a fixed coordinator near the patient. The patient must be moved to a different, known, room for a test. This room also has a fixed coordinator. The patient will be moved past multiple other coordinators that are inappropriate for association.

9. Multi-Periodic GTS Description
May 2012
Multi-Periodic GTS
Description
A enhancement to GTS which allows for a defined period between time slots (greater than the beacon interval), resulting in more efficient resource allocation for long interval, periodic traffic applications.
Use Case
As wireless monitoring proliferates, sensors will remain on patients for longer periods of time, requiring more efficient use of power (maximizing battery life) for low duty cycle applications with periodic data.
Raymond Krasinski, Philips

10. Association Proxy Description
May 2012
Association Proxy
Description
A method for associating a fixed set of sensors to a coordinator when not in close proximity or where there are multiple coordinators in proximity.
Use Case
A patient upon admission to the hospital is assigned a room. Before being moved to the room the patient is first taken to a central station where sensors are applied and are associated to the coordinator in the patient room using a proxy device.
