May 2012 IEEE 802. 15 -12 -0261 -01 -004 j IEEE 802. 15. 4 j Task Group TG 4 J MAC Feature Letter Ballot 81 Submission Slide 2 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j Scope of MBAN Task Group • Draft an amendment of 802. 15. 4 for MBAN – This amendment defines a physical layer for IEEE 802. 15. 4 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. Submission Slide 3 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j FCC MBAN Rules • Allow use of the 2360 -2400 MHz band, on a secondary basis, for monitoring, diagnosing or treating patients (no voice). – 2360 -2390 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 rechannelization out of the spectrum, to accommodate the primary user Submission Slide 4 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j 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 Submission Slide 5 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j Letter Ballot 81 MAC Features • • Channel Switch Notification Coordinator Switch Multi-Periodic GTS Association Proxy Submission Slide 6 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j 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. Submission Slide 7 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j 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. Submission Slide 8 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j 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. Submission Slide 9 Raymond Krasinski, Philips

May 2012 IEEE 802. 15 -12 -0261 -01 -004 j Association Proxy Description • A method for associating a fixed set of sensors to a coordinator when not in close proximity and 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.
